I'd personally do it slightly differently and have my configuration file more of a "control file". For example:
/path /path2 /laptopBackup
/tmp /test /bigmachine
etc.. 1 line per mount, 3 fields per line (source, destination, backupfoldername)
Then use something like :
while read SOURCE DESTINATION BACKUPFOLDERNAME
do
<stuff>
done < ${configfile}
(removed the cat so as not to shame myself further :( )
|
I'm having some difficulties with this. Basically, for work I need a bash script that backs up a variable number of directories that are stored in a config file.
I'm sure I need to import the list from the config file and just use a loop to copy all the directories across. I have it working for a single directory. My code is below. I've cut it down to a minimum.
#!/bin/sh
if [ ! -f ./backup.conf ]
then
echo "Configuration file not found. Exiting!!"
exit
fi
. ./backup.conf
unset PATH
# make sure we're running as root
if (( `$ID -u` != 0 )) ; then { $ECHO "Sorry, must be root. Exiting..."; exit; } fi ;
# attempt to remount the RW mount point as RW; else abort
$MOUNT -o remount,rw $SOURCEFILE $DESTINATIONFOLDER ;
if (( $? )); then
{
$ECHO "snapshot: could not remount $DESTINATIONFOLDER readwrite";
exit;
}
fi ;
# step 2: create new backup folder:
$MKDIR $FULLPATH
**Loop should go here**
#copy source directories to backup folder
$RSYNC \
-va --delete --delete-excluded \
--exclude-from="$EXCLUDES" \
$SOURCEFILE $FULLPATH;
The config file is as follows
SOURCE=path
DESTINATION=path2
BACKUPFOLDERNAME=/laptopBackup
My question is what is the best approach to do this task. i.e how should I format the config file to import a variable amount of paths to an array? or is there a better way of doing this?

You could copy it with command
select * into new_table1 from primarytable
This will create a table named new_table1 with data from primarytable.
You must of course backup the whole database.

No, the Caches directory can be deleted by the user manually. The Temp dictionary should be delete after/during the user exits the app. The Caches directory is for all data your app needs but can recreate if it doesnt exist anymore (all Data not created by the user, but by the developer)

I download some data and save it to Library/PrivateDocuments directory. every file i download in this- Library/PrivateDocuments directory i set "do not backup" attribute. and apple still says :
"In particular, we found that on launch and/or content download, your
app stores too much data (10.3 MB after app launch) in the incorrect
location. To check how much data your app is storing:
Temporary files used by your app should only be stored in the /tmp
directory; please remember to delete the files stored in this location
when the user exits the app."
p.s i need that files to stay there.. at first i check for files and if some of them doesn't exists i download them. so they aren't temp files and i don't want to delete them..
and i don't know what to do.. if you are familiar with this problem please give me a hint..
thanks.

Rejected iOS app reason : Data Storage Guidelines

If you make an image of the filesystem, you will get it exactly as it was in the moment you did the image (links and everything, these are part of the filesystem information). You're probably mistaken the filesystem itself with the logical entities it represents (files, directories...).
I personally used standard tool dd long time ago to make/restore partition backups, and it worked perfectly.
|
I have a Linux filesystem that I would like to make backups of. I want to image the entire filesystem, for later restoration if needed. However, this particular filesystem contains multiple hard links to some files, which must be preserved by the backup and properly re-linked when it is restored, exactly as they are now.
Is there a Linux tool that can efficiently image a filesystem, preserving hard links in the process? I would prefer an open source one if possible, although I'm willing to consider all options.
|

You can simply serialize and deserialize your datastructure, it certainly looks Serializable. Tip
Or if you prefer more robust solutions, you can create DB tables with simple DBs (outside the process of your app), so it can survive the crashes, and reload your datastructure. (For example some simple Java based DBs: JavaDB, h2, HSQLDB)

in my JAVA program I scan folders every hour an check those for changes. If there's a change I receive a unique number to identify this file. These data are stored in a field variable. So I need to store the data locally for the case of restart or crash.
My Datastructure:
Map<String, Long> currentFiles = new HashMap<String, Long>();
Map<String, Long> prevFiles = new HashMap<String, Long>();
Which backup should I use? The data should be save against modifications. The data aren't confidential.

To configure s3cmd in order to be able to run in in your scripts run:
s3cmd --configure
Run this command from the user who has to run the backup script or copy the generated file to that user home directory.
To delete file with s3cmd you use the del command, so, in your script you should call s3cmd like this:
s3cmd del s3://bucketname/file
Of course, you can also use wildcards:
s3cmd del s3://bucketname/file*
You can name you backup files with the date:
db.backup.20130411.tgz
and use the date in order to delete previous backups.
Btw, in the s3ql project there is an expire_backups script that might be doing already what you want to do.

I need a script for s3cmd that sends the deletion command for some files in my Amazon S3 bucket. I know there's this method built-in but it's not useuful. Let's see why.
At the moment I have a script that backups my database every midnight and my websites files every Friday and Tuesday (still at midnight).
The script I'm looking for should delete files in order to have on the bucket only: 1 backup per month (let's say, of the 1st day of every month) of both db and files.
And leave all the backups (every day for db and tuesday and friday for files, so the "default" behavior) for the last 7 days.
Example, if I'm on june 17th 2012 the situation should be:
1st January 2012: db and files
1st february 2012: db and files
1st march 2912: db and files
1st april 2012: db and files
1st may 2012: db and files
10th june 2012: db
11th june 2012: db
12th june 2012: db and files
13th june 2012: db
14th june 2012: db
15th june 2012: db and files
16th june 2012: db
Then on july 2nd 2012 the bucket should contain:
1st of jan, feb, march, apr, may, june: both db and files
last 7 days: "default" backups untouched (files backup only on tuesday and friday and db every midnight).
The script would automate what I'm doing manually right now (I already have just 1 backup per past month, so I have to delete backups starting from 7 days ago going back to the last 1st-of-the-month backup).
Sorry for the convoluted question, I hope it's clear enough. :D

Akeeba Backup has a database tables exclusion functionality. Refer to their documentation here for answers:
https://www.akeebabackup.com/documentation/akeeba-backup-documentation/database-tables-exclusion.html

I have a database, my_db; and I have a joomla site, my_joomla_site, that stores its tables there. However, my_db also has other tables that are UNrelated to my_joomla_site.
When I use Akeeba Backup to backup my_joomla_site, Akeeba packs all of the tables from my_db. I only want it to pack/zip the appropriate tables of course.
Is there a way to tell Akeeba to only pack the appropriate tables?
|
joomla's akeeba is backing up ALL tables on my db

There are many differences.
In A you are writing to gzip which compresses the data before writing to disk. B writes plain sql files which can be 5-10 times bigger (results from my database). If your performance is disk bound this could be the solution
-c = "full inserts" is not specified in A
-q is not specified in A
for large databases INFORMATION_SCHEMA queries can be a pain with mysql (try executing SELECT * FROM information_schema.columns. For B every dump has to do these queries while A has to do this only once.
|
I use two different ways to backup my mysql database. mysqldump with --all-databases is much faster and has a far better performance than a loop with to dump every database in a single file. Why? And how to speed up performance for the looped version
/usr/bin/mysqldump --single-transaction --all-databases | gzip > /backup/all_databases.sql.gz
and this loop over 65 databases even with nice:
nice -n 19 mysqldump --defaults-extra-file="/etc/mysql/conf.d/mysqldump.cnf" --databases -c xxx -q > /backup/mysql/xxx_08.sql
nice -n 19 mysqldump --defaults-extra-file="/etc/mysql/conf.d/mysqldump.cnf" --databases -c dj-xxx -q > /backup/mysql/dj-xxx_08.sql
nice -n 19 mysqldump --defaults-extra-file="/etc/mysql/conf.d/mysqldump.cnf" --databases -c dj-xxx-p -q > /backup/mysql/dj-xxx-p_08.sql
nice -n 19 mysqldump --defaults-extra-file="/etc/mysql/conf.d/mysqldump.cnf" --databases -c dj-foo -q > /backup/mysql/dj-foo_08.sql
mysqldump.cnf is only used for the authentication, there are no additional options there.

mysqldump with single tables much slower than with --all-databases

I think this script will be helpful to you for taking dabase backup
<?php
backup_tables(‘hostaddress’,'dbusername’,'dbpassword’,'dbname’);
/* backup the db OR just a table */
function backup_tables($host,$user,$pass,$name,$tables = ‘*’)
{
$link = mysql_connect($host,$user,$pass);
mysql_select_db($name,$link);
//get all of the tables
if($tables == ‘*’)
{
$tables = array();
$result = mysql_query(‘SHOW TABLES’);
while($row = mysql_fetch_row($result))
{
$tables[] = $row[0];
}
}
else
{
$tables = is_array($tables) ? $tables : explode(‘,’,$tables);
}
//cycle through
foreach($tables as $table)
{
$result = mysql_query(‘SELECT * FROM ‘.$table);
$num_fields = mysql_num_fields($result);
$row2 = mysql_fetch_row(mysql_query(‘SHOW CREATE TABLE ‘.$table));
$return.= “\n\n”.$row2[1].”;\n\n”;
for ($i = 0; $i < $num_fields; $i++)
{
while($row = mysql_fetch_row($result))
{
$return.= ‘INSERT INTO ‘.$table.’ VALUES(‘;
for($j=0; $j<$num_fields; $j++)
{
$row[$j] = addslashes($row[$j]);
$row[$j] = ereg_replace(“\n”,”\\n”,$row[$j]);
if (isset($row[$j])) { $return.= ‘”‘.$row[$j].’”‘ ; } else { $return.= ‘”"‘; }
if ($j<($num_fields-1)) { $return.= ‘,’; }
}
$return.= “);\n”;
}
}
$return.=”\n\n\n”;
}
//save file
$handle = fopen(‘db-backup-’.time().’-’.(md5(implode(‘,’,$tables))).’.sql’,'w+’);

$command = "mysqldump --opt -h $dbhost -u $dbuser -p $dbpass ".
"test_db | gzip > $backup_file";

You don't need to modify the method. Convert your string to URL.
NSURL *url = [NSURL URLWithString:@"your string"];
|
In order to follow the Data Storage Guidelines I must use the below method to add a flag to say to not back it up to iCloud. However, the parameter here is for a NSURL. I need to pass it a NSString like from a line like so
return [[self offlineQueuePath] stringByAppendingPathComponent:@"SHKOfflineQueue.plist"];
Here is the method that takes in a URL.
- (BOOL)addSkipBackupAttributeToItemAtURL:(NSURL *)URL
{
if (&NSURLIsExcludedFromBackupKey == nil) { // iOS <= 5.0.1
const char* filePath = [[URL path] fileSystemRepresentation];
const char* attrName = "com.apple.MobileBackup";
u_int8_t attrValue = 1;
int result = setxattr(filePath, attrName, &attrValue, sizeof(attrValue), 0, 0);
return result == 0;
} else { // iOS >= 5.1
NSError *error = nil;
[URL setResourceValue:[NSNumber numberWithBool:YES] forKey:NSURLIsExcludedFromBackupKey error:&error];
return error == nil;
}
}
Anyway, how would I modify the method above to achieve the same while taking in a NSString as a parameter?
Thanks!

addSkipBackupAttributeToItemAtURL -> NSString parameter?

Assuming that you are storing the ringtone as a content:// Uri value, I would use either openInputStream() or getType() on ContentResolver. getType() is probably "the most lightweight", but it might be prone to false negatives (e.g., ringtone exists but the MIME type cannot be determined for some reason).
|
In my app, I'm storing the user's choice of a ringtone in a SharedPreference file. When the app is reinstalled and the backup is restored, I want to check if the ringtone still exists on the device, because if it doesn't I would want to use the default ringtone (as opposed to playing nothing).
So to do so, I plan on overriding the onRestore method and checking if the ringtone is available on the device.
So how can I go about checking if a ringtone exists on the Android device (I would prefer the most lightweight method possible)?

Maybe you can include a copy of pg_dump.exe binary for Ms Windows (and required dlls) with your application. Then invoke it with proper parameters from a GUI.

You can use xcopy to recreate the file structure with the /T switch. You will also need to use the /E switch to copy empty directories and subdirectories.

I currently have a batch file which reads a filelist from folder A, if it's over a certain date copies it to folder B and deletes the original.
The problem is that I would like the batch file to recreate the file structure inside folder A, and I'm not quite sure how to do this. Here's the code:
echo off
echo REM :- THE FOLLOWING FILES ARE OLDER THAN 7 DAYS AND CAN BE MOVED TO BACKUP -:
pause
forfiles /p c:\test\one /s /m *.gif /c "cmd /c dir /b/s/t:w @path"
echo.
echo REM :- CONTINUE TO MOVE THOSE FILES TO THE BACKUP LOCATION -:
pause
forfiles /p c:\test\one /s /m *.gif /c "cmd /c mkdir c:\test\two\@relpath"
echo.
pause
forfiles /p c:\test\one /s /m *.gif /c "cmd /c copy /-y @path c:\test\two\@relpath"
pause
echo.
echo REM :- THE FOLLOWING FILES EXIST IN THE BACKUP LOCATION -:
echo.
pause
dir "c:\test\two" /a/s/b /o:gn
echo.
echo REM :- CONTINUE TO DELETE THOSE BACKUPS -:
pause
rd /s "c:\test\two"
echo.
pause
The problem is that @relpath seems to take the whole path and filename, so in folder B I end up with each filename inside a folder of its own name (e.g. 'filename.gif' inside a folder of the same name). How can I strip the filename from the path, create a file structure in folder B based on that, and then copy the file to the correct place?
Thanks

Avoid using dd; programs like ddrescue have a much better status reporting, imply noerror, and conversion is not desired on disk images at all.
|
I will be backing up a large (750GB) disk to an external USB disk using dd.
What is the most appropriate use of notrunc, noerror and sync conversion arguments? It seems some people use them in different ways, or not at all.
Also, what is the best block size? USB is likely to be the bottleneck here.
dd if=/dev/sda bs=1M | gzip -c > /mnt/sdb1/backups/disk.img.gz
gzip -dc /mnt/sdb1/backups/disk.img.gz | dd of=/dev/sda bs=1M

Don't put a space or equals sign between the -p and the password. Also, you are missing a space before the -p.
$command = 'mysqldump -h' . $dbhost . ' -u ' . $dbuser . ' -p' . $dbpass . ' '. $dbname . ' > ' . $backupFile ;

The best bet will be to use MySql Schedular, I know MySQL 5.1.6 come with this, check out this. For more on how you can backup MySql database check out
Using MySQL Schedular you can do something like
CREATE EVENT MyEvent
ON SCHEDULE AT TIMESTAMP '2011-12-30 23:59:00'
DO
SELECT * INTO MY_NEW_TABLE FROM MY_CURRENT_TABLE;

One liner to remove files more than 7 days old:
find ${path_to_files} -daystart -maxdepth 1 -mtime +7 -exec rm -rf {} \; &>/dev/null
Maybe you could adapt it to your needs, by ignoring the files exactly x%15 days old...

I am using Webmin to backup automatically every day. I want to automatically delete all backups older then 7 days, unless they are every 15 days. I guess I need to write some sort of bash script to do this, does anyone know of a way built into webmin, or a script that does this already.
Summary:
- Daily Backups are already being made.
- Backups need to be retained for 7 days from current date, and removed otherwise UNLESS it is every 15 days.
Thanks

Is there some way to remove workspaces and build controller settings from TFS backup (before it will be restored to second server)?
I'm fairly confident that the answer is, unfortunately, No.
TFS backup (including backup to restore on another server) is at the database level, and that is where all the state is held. To move only part of the data would require moving only part of the database1.
It is quite possible to use the command line to enumerate and delete workspaces (see tf workspace /delete) of other users from account with sufficient access.
1 Or database*s* is using TFS 2005 or 2008.

There are two TFS servers. We need to move data from first server to second server. We need to move all data else workspaces and build controller settings. But if to do backup of first TFS server, then it contains these data too....
Is there some way to remove workspaces and build controller settings from TFS backup (before it will be restored to second server)?
Thanks to Richard, I will specify the question: did somebody manage to find the set of sql commands for to delete from backup database (yes, TFS2010) the data about workspaces and build controller settings and break nothing?

I think you are just missing a -c on the gzip line, try:
$MYSQLDUMP -u $MYSQLUSER -p$MYSQLPASS --all-databases | $GZIP -c9 > $BACKUP_DIR/$NAME.sql.gz

I am trying to make a bash script to backup my sevrer, however it is creating empty tar archive and empty sql files and I don't know why. Can anyone see the problems here?
#!/bin/bash
SERVER_DIR="/var/www/vhosts/site.org"
DATE=$(date +"%d-%m-%Y")
BACKUP_DIR="/backups/$DATE"
NAME="full-$DATE"
MYSQLUSER="admin"
MYSQLPASS="pass"
MYSQLDUMP="$(which mysqldump)"
GZIP="$(which gzip)"
mkdir -p $BACKUP_DIR
tar -zcvf $BACKUP_DIR/$NAME.tar.gz $SERVER_DIR
$MYSQLDUMP -u $MYSQLUSER -p$MYSQLPASS --all-databases | $GZIP -9 > $BACKUP_DIR/$NAME.sql
find /backup/ -mtime +31 -exec rm -rf {} \;
|
Bash backup script
|
You could always just dump ALL the databases:
mysqldump --all-databases | gzip -9 > /backup/dbs.bak.gz
That'd free you from having to keep track of which dbs there are. The downside is that restoring gets a bit more complicated.
As for using root, there's no reason you couldn't create another account that has permissions to do backups - you should never use the root account for anything other than initial setup.
|
I have several websites hosted on a VPS and am currently performing database backups by running a shell script via cron that looks something like this:
mysqldump -uusername1 -prootpassword dbname1 > /backup/dbname1.bak
mysqldump -uusername2 -prootpassword dbname2 > /backup/dbname2.bak
mysqldump -uusername3 -prootpassword dbname3 > /backup/dbname3.bak
I have a couple of concerns about this process.
Firstly, I'm using the root server password to perform mysqldump, and the file is being stored in clear text on the server (not publicly accessible or anything, but there are obviously concerns if I grant other users access to the server for one reason or another). I'm using root because it's simpler than tracking everybody that creates a database down and asking them for their specific db passwords.
Secondly, this process only works if people inform me that they've added a database (which is fine for the most part, we're not doing anything super complicated over here). I would prefer to have a backup of everything without worrying that I've overlooked something.
|
How best could I optimize the way I'm backing up MySQL databases?
|
I always do this just via ssh:
tar czf - FILES/* | ssh me@someplace "tar xzf -"
This way, the files end up all unpacked on the other machine. Alternatively
tar czf - FILES/* | ssh me@someplace "cat > foo.tgz"
Puts them in an archive on the other machine, which is what you actually wanted.
|
I have a large number of files which I need to backup, problem is there isn't enough disk space to create a tar file of them and then upload it offsite. Is there a way of using python, php or perl to tar up a set of files and upload them on-the-fly without making a tar file on disk? They are also way too large to store in memory.
|
is it possible to take a large number of files & tar/gzip and stream them on-the-fly?

Do you have a timestamp field on your database? Using a timestamp with ON UPDATE CURRENT_TIMESTAMP clause would allow you to know the modification time of each row. That way, you could easily do a SELECT query on rows WHERE timestamp is greater than a given value.

I have 2 MySQL databases on the same Linux box. They aren't super large, but some tables hold around 500,000 rows, increasing by about 40,000 rows per month.
What I need to do is to write a partial backup from one database to the other once per day. This partial backup is a snapshot and apart from the backups will not have any fresh data written to it. It contains only some of the tables of the main db, and from those tables only some of the fields.
It is easy enough to write a PHP script that deletes the backup database, and then recreates it with the desired data to get a fresh snapshot, however i am wondering if there is a way to do this incrementally with PHP and only write new or changed data.

No, it is not safe to delete transaction log. But you can shrink it:
2005
backup log XXX with truncate_only ....
dbcc shrinkfile
2008
Alter database xxx set recovery simple
dbcc shrinkfile
Alter database xxx set recovery full
can I restore a transaction log backup to another server
Yes, you can, but before you need to restore LAST FULL backup to another server.

You can create a symfony task. If you pass in an environment (i.e. dev, prod) or connection you get access to the Doctrine connection manager and create a connection. You can use that connection to make a database dump or get the connection details from the connection manager.
You can use the doctrine insert sql task as template for your task. I've done similar in the past.

I have just inherited a system running on EC2, running several instances and there are some large data volumes - 2TB+. Any suggestions on best (cheapest + quickest) way to back these up and move to local machines ? I think the files will tar and zip efficiently but still be several 100g. Should I just forget about pulling the data down and build new instances based on ec2 backups.

There are lots of devices that are installed using what's called a "No Driver" INF. These INFs provide enough information such that Device Manager will have some info to show for the device (thus avoiding them appear in the "unknown devices" category) but don't actually install any drivers.
These devices do not need drivers because they are managed by either the O/S itself, the BIOS, or both. Usually these devices are all "installed" using machine.inf, which has a giant list of known no driver devices.
As for any software that claims to back the drivers for these devices up, either they're just copying the INF or they're full of it because there's nothing but the INF to back up.
-scott
|
I'm stuck. To cut long story short, the task is to enumerate all driver files for backup. For some drivers like display adapter driver, I use
SetupScanFileQueue(queueHandle,
SPQ_SCAN_USE_CALLBACKEX,NULL,
DumpDeviceDriversCallback,&count,&scanResult)
from setupapi and that's working fine as in DumpDeviceDriversCallback I can get the Source of the device driver file and then copy it to backup location one by one.
However, the same function ignore the callback for system drivers. For example for "Direct memory access controller" I can not get the list of files. Funny thing, but windows device manager also can not find any files for some of the system devices.
Some special software like DriverMax and DoubleDriver actually CAN backup those driver. So, this is the problem that may be solved.
Anyone can explain me what is going on here?

You could use the logrotate(8) tool that came with your distro. :) The manpage has an example that looks close to your need:
/var/log/news/* {
monthly
rotate 2
olddir /var/log/news/old
missingok
postrotate
kill -HUP `cat /var/run/inn.pid`
endscript
nocompress
}
Well, not the monthly bit, or restarting inn :) but I hope you get the idea that you could easily add a new config file to /etc/logrotate.d/ and not worry about it again. :)

Hello
I keep my log files under /opt/project/logs/ and I want to daily copy these to /opt/bkp by compressing them.
For this I have written this and works well:
#!/bin/bash
getdate(){
date --date="$1 days ago" "+%Y_%m_%d"
}
rm -rf "/opt/bkp/logs/myapp_log_"$(getdate 365).gz ;
/bin/cat /opt/project/logs/myapp.log | gzip > /opt/bkp/logs/myapp_log_`date +%Y_%m_%d`.gz ;
echo "" > /opt/project/logs/myapp.log ;
However it is not functional or general, I will have several applications saving files with their names ie app1.log app2.log under the same /opt/project/logs/ folder. How can I make this as a "function" where script reads each file under /opt/project/logs/ directory and taking backup of each file ends with .log extension?

If you can and are allowed to create `database links, create one and then copy the data over the database link.
That would be: on the destination db:
create database link db_link
connect to <username>
identified by <password>
using '<connection_string>";
then
insert into projects
select * from projects@db_link
where ....
Or,alternatively, try the copy command of SQL*Plus.
SQL> copy from <db_src> to <db_dest> append projects using select * from projects where ....

If you check out the assembly directory on the Win7 machine (GAC) you'll see an entry called Microsoft.SqlServer.ConnectionInfo. (Browse to %windir%\assembly) On my machine it looks like this:
In my case I'm using version 10.0.0.0. In your case, you will at least see version 9.0.242.0 as that is what your program is compiled against (I find it unlikely that you're not referencing the dll from the GAC). If you don't have the same version installed on both machines, you've spotted the problem and you need to update the client library accordingly. I think it's likely that you have a newer version running on the XP machine, since you just installed 2008 there.

There's no way to rename that directory using standard mercurial configuration options. If you're on unix, and I'm guessing your are if .hg sounds hidden, you could use a pre-backup script (or cron job) to snapshot it using cp -al into something with a different name. Using -l gets you hardlinks, so it won't actually take up extra disk.
However, most people back up their .hg repositories with a push to a different mercurial server, which can be easily scripted too.

You are going to want to look into version control. There are many options, the most popular of which are SVN, git and mercurial. The latter two are probably along the lines of what you're looking for.
It is generally good practice to use version control for projects of any real size.

The T-Log will only have portions of it marked inactive, when the database has a transaction log backup on it performed - a portion (vlf) is only marked inactive if there are no outstanding transactions within the VLF.
A full backup, whether in fully logged mode or bulk logged mode will not mark any portions of the t-log inactive.

I have clients out there running an SQL Server Express 2005 and each of these needs a backup each month and that backup needs to be moved to our server in case they lose their backup. Our software automatically backs up the database each month but we have to manually go in and copy it across. Is there any way to automate the copying of files up to 800 megs from their machine to ours each month perhaps using FTP? Also, if using FTP it has to support resume in case we lose the connection three querters through which happens quite often. I would like to write this functionality into our VB.net application that only requires the .net framework and not use any third party controls.

I've used rsync just fine with moving files around and using them on other boxes. I've never done it with the MYSQL running live, but i've restored from the files in /var/lib/mysql before with no problems. It's a good way to "copy" over databases for your "development" box. I suggest shutting down mysql, moving the files over then starting it back up again. That is how I've done it when necessary.
myqldump gives you nice neat SQL code though, good if you ever need to "tweak" something with sed along the way.
I'd have no worries about using rsync though. I use it for many purposes including pushing code updates out to client machines.
|
I've usually use mysqldump to export a database. However, when the database is really large, it seems much faster and less intensive to just gzip the database files directly without involving the MySQL deamon and copying that to the other database.
eg:
tar -czvf {db_name}.sql.tgz /var/lib/mysql/{db_name}
Is this a good method of doing this? What are the (dis)advantages?
I also read another post here that mentioned:
rsync /var/lib/mysql/ ...
Would it be a good option to just use rsync to keep a backup db in sync with the development db?

If you did a full recovery then that is the result I would expect.
The DROP SCOTT.DEPT action was applied do the database when you recovered and fed RMAN all the outstanding archived logs.
You want to do a point in time recovery to a time before you issued the DROP statement.
rman target sys/manager@db
RUN
{
SET UNTIL TIME 'Feb 3 2010 08:30:00';
RESTORE CONTROLFILE ;
ALTER DATABASE MOUNT;
RESTORE DATABASE;
RECOVER DATABASE;
}
More info here:
Oracle 10.2 Backup and Recovery Basics - Performing Database Point-In-Time Recovery
ALternately you could leave the RECOVER DATABASE step off and just RESTORE the database followed by an OPEN RESETLOGS. That would allow you to skip applying any changes in the Archived Logs.

I did that, but I was wondering what happens when some program does write to the disk nevertheless during the process.

It's interpreting your dots as different prefixes, while in fact, I'm guessing they're just part of your database name...? In that case, increasing the amount of prefixes allowed is not what you want, but rather something like this:
ALTER SCHEMA dbo TRANSFER [[email protected]].tablename
|
I am transferring a database from one hosting provider to another. The current provider uses the domain name as part of the user name. The domain name is a .co.nz domain. So some objects in the database have a fully qualified name of [email protected].
Im trying to alter the schema of these objects to put them into a dbo schema using:
ALTER SCHEMA dbo TRANSFER [email protected]
But i get Error Message 117:
The object name '[email protected]' contains more than the maximum number of prefixes. The maximum is 1.
In another database I get the same error message but the maximum number is 2. So obviously the maximum number of prefixes can be set... somewhere. How do I increase the maximum number of prefixes so I can transfer securables out of the [email protected] and into the dbo schema?

I'm using the same technique to make a backup from database. I've created a stored procedure as follows.
Create Procedure [dbo].[CreateBackup]
As
Begin
Declare @path nvarchar(256),
@filename nvarchar(256),
@currentDateTime datetime
Set @currentDateTime = GetDate()
Set @path = 'C:\DBBackup\'
Set @filename = @path + Cast(DatePart(month, @currentDateTime) As nvarchar) + Cast(DatePart(day, @currentDateTime) As nvarchar) + '.bak'
Backup Database Foo To Disk = @filename
Set @currentDateTime = DateAdd(day, -3, @currentDateTime)
Set @filename = 'del ' + @path + Cast(DatePart(month, @currentDateTime) As nvarchar) + Cast(DatePart(day, @currentDateTime) As nvarchar) + '.bak'
Exec xp_cmdshell @filename
End
To use the xp_cmdshell, you should enable it before.

Using osql command, SSQL backup of a database is created.
It is saved to Disk.
Then renamed to match the date of the day backup was taken.
All these files are saved in a single folder all the time.
for example:
Batch1.bat does the following
1) Created backup.bak
2) renamed to backup 12-13-2009.bak (this is done by the combination of % ~ - etc to get the date parameter)
This is now automated to take backup everyday by Task scheduler in Windows.
Can the batch file also be modified to delete backup files older than 7 days? if so, how ?
If it is not possible via batch file, other than manually deleting the files are there any other alternatives to automate the deleting job ?
Thanks in advance, Balaji S

I have one stored procedure to backup the database. It will backup metadata as well as data.
Is there any option to back up the database with out data. ie, back up only the schema (Empty tables).
I don't want to script the database.
|
backup SQL Server 2005 database without data

All the objects in our databases are maintained in code - tables, view, triggers, stored procedures, everything - if we expect to find it in the database then it should be in DDL in code that we can run. Actual schema changes are versioned - so there's a table in the database that says this is schema version "n" and if this is not the current version (according to the update code) then we make the necessary changes.
We endeavour to separate out triggers and views - don't, although we probably should, do much with SP and FN - with drop and re-create code that is valid for the current schema version. Accordingly it should be "safe" to drop and recreate anything that isn't a table, although there will be sequencing issues with both the drop and the create if there are dependencies between objects. The nice thing about this generally is that we can confidently bring a schema from new to current and have confidence that any instance of the schema is consistent.
Expanding to your case, if you have the ability to run the schema update code including the code to recreate all the database objects according to the current definitions then your problem should substantially go away... backup, restore, run schema maint logic. This would have the further benefit that you can introduce schema (table) changes in the dev servers and still keep the same update logic.
I know this isn't a completely generic solution. And its worth noting that it probably works better with database per developer (I'm an old fashioned programmer, so I see all problems as having code based solutions (-:) but as a general approach I think it has considerable merit because it gives you a consistent mechanism to address a number of problems.
|
We want to have our test servers databases updated from our production server databases on a nightly basis to ensure we're developing on the most recent data. We, however, want to ensure that any fn, sp, etc that we're currently working on in the development environment doesn't get overwritten by the backup process. What we were thinking of doing was having a prebackup program that saves objects selected by our developers and a postbackup program to add them back in after the backup process is complete.
I was wondering what other developers have been doing in a situation like this. Is there an existing tool to do this for us that can run automatically on a daily basis and allow us to set objects not to overwrite (without requiring the attention of a sysadmin to run it daily).

BackupRead is not a magical function that lets you read any file. For starters, you need to run as a user with backup privilege. Secondly, you must respect the FilesNotToBackup registry key. You also have to call CreateFile with FILE_FLAG_BACKUP_SEMANTICS. But even with that in mind, I'm not sure if it's the bets way to backup the registry.

So you're not using the default aspnetdb? The membership tables are contained in your database? These would be have names with the prefix aspnet_. Perhaps you also need to back up aspnetdb?

I'd do nothing. Or have SIMPLE permanently.
Changing the recovery model back to full will require a full backup anyway to preserve integrity later on. You'll have a gap in your LSN chains otherwise.
You've mentioned differential backup, so I assume your full is not each night.
So, putting this together means you'll use more disk space for your full backup than for the LDF file.
|
I have a nightly job that does a bunch of inserts. Since I have a full recovery model, this increases my transaction log size.
Currently I have my log file big enough to accommodate these transactions, but the issue is that the transaction log is mostly empty throughout the day.
Is it an issue (besides disk space) to have a huge (mostly empty) transaction log?
I'm thinking about switching the database to simple recovery before the job, running the job and then switching it back to full recovery. I can have the transaction logs just not be backed up until our nightly differential backup comes around and then i can start the transaction log backup again.
Suggestions?

One simple solution for backup:
Call mysqldump from php http://dev.mysql.com/doc/refman/5.1/en/mysqldump.html, and save the backup file somewhere convenient.
This is a safe solution, because you have mysqldump on any mysql installation, and it's a safe way to generate a standard sql script
It's also safe to save the whole database.
Be careful with blobs, like saved images inside database
Be careful with utf-8 data
One simple solution for restore:
Restore operation can be done with the saved script.
First disable access to the the site/app.
Take down the database.
Restore the database from the script with mysqlimport http://dev.mysql.com/doc/refman/5.0/en/mysqlimport.html

For the database, do a regular Microsoft SQL Server backup and restore (or whetever your hosting company lets you do).
Beyond the database, you probably want to make a copy of the Web.config, because you will be transferring some of those settings to a new machine, and you want a copy of any files that you have customized, like in the "custom" folder.

Setting up a cronjob to run a script that does a mysqldump and stores the dump on a separate disk from the database itself (or a remote server) is a quite easy and efficient way to backup a database in my opinion. You could even have it dump every database with the --all-databases switch
If you have more than one MySQL server, you could also use replication
Frequency of backups depends on how much data you are willing to lose in case of a failure.

In MySQL, what are the practices to backup databases?
|
SSARC is not really a backup tool. I wouldn't recommend it. It's more like a way to cut-n-paste segments of a VSS repository between different databases. It's also not without side effects. At minimum, items in the source database get marked as archived. At worst, they get deleted.
The best way is to take your DB offline, zip it up (or RAR, whatever), and copy the *.zip file somewhere safe. VSS was designed back in the days when file sharing was the only cross-platform protocol reliably available on PC LANs, so the filesystem is the database. Compared to modern client-server systems, VSS architecture has many flaws which I'm sure you're aware of -- but you may as well use its convenience to your advantage.

I was wondering what the best approach might be for creating a backup of my organisation's SourceSafe database, and moving it to a share on another server? Currently we have a scheduled job which runs a batch file, which in turn executes a PowerShell script.
This Powershell script creates a backup file (using SourceSafe command-line arguments), moves it to a new server (via a drive that has been mapped on the SourceSafe server), and sends the output of the SourceSafe backup to our administrator via e-mail.
This process works for the most part, but I can't help but feel there are more streamlined approaches or tools we should be utilizing. Any advice is welcomed!

SourceSafe backup script - best approach?

I use the following script to send a small dump to a dedicated mail account.
This of course assumes you can send mails from your machine using the mail command.
#!/bin/bash
gzdate=`/bin/date +%Y-%m-%d_%H%M`;
gzfile=dump_${gzdate}.sql.gz
[email protected]
dumpuser=username
dbname=mydb
mysqldump --single-transaction --opt -u ${dumpuser} ${dbname} | gzip > ${gzfile}
if [ $? == 0 ]; then
( echo "Database Backup from ${gzdate}:"; uuencode ${gzfile} ${gzfile} ) | mail -s "Database Backup ${gzdate}" ${mailrecpt};
else
( echo "Database Backup from ${gzdate} failed." ) | mail -s "FAILED: Database Backup ${gzdate}" ${mailrecpt};
fi
You just need to adapt the variables at the top.

We're running a CentOS server with a lot of MySql databases atm, what I need is a really easy way for us to back those up. Since many of them are under a couple of meg. Dumping, zipping them up then sending them to a secure Google Apps account sounds like a pretty good idea.
So what I need is: a script that will dump and zip the database, then email it somewhere, if it fails email somewhere else.

I'll try the 'soft-upgrade' way described in the documentation but do you think this will work?
I don't know enough about GEOS to say for sure, but it sounds like a good thing to try. From the docs you linked to:
If a soft upgrade is not possible the script will abort and you will be warned about HARD UPGRADE being required, so do not hesitate to try a soft upgrade first.
Otherwise, I'd just follow their "hard upgrade" directions, which appear to be functionally equivalent to the usual pg_dump/pg_restore approach used to upgrade to a new major version of PostgreSQL. There's plenty more information in the Postgres documentation about how to do that; it's a very safe procedure and, as the official migration method, is extremely well supported.
One thing you may wish to consider is upgrading to the PostgreSQL 8.4 beta while you're doing all of this work. It's beta software, true, but that might be acceptable for your environment, and if it is suitable, then you get the new features of 8.4 plus the ability to do a soft upgrade to 8.4 final (as the on-disk formats are not expected to change after the start of beta).

Current situation:
Ubuntu 8.04 server edition (live server)
Postgresql 8.3.7 (from standard repositories)
Postgis 1.3.3 (from standard repositories)
GEOS 2.3.4 (from standard repositories)
Problem:
GEOS contains bugs which are fixed in the 3.0 release.
I have encountered these and need to upgrade GEOS/Postgis to include the GEOS fixes.
Where i'm standing now:
On a test machine with nearly identical setup, i removed the postgis-packages and tried to recompile Geos 3.1.0 against Postgis 1.3.5 and Postgresql 8.3.7.
After fixing some linking and path problems this works.
My specific question:
What is the best way to migrate my databases (tables, functions, triggers, gist indexes, data...) from the 'based on older geos/postgis' version to the 'newer' one?
I'll try the 'soft-upgrade' way described in the documentation but do you think this will work?
What's the best way to make a full backup of this postgis-enabled database so i can completely restore it on the 'newer postgis version' i'm compiling?

I'm working on some documents on a laptop which is sometimes offline (it runs winXP).
I'd like to backup automatically the documents to a folder to a remote location so that it runs in the background.
I want to edit the documents and forget about backuping and once online - have it all backuped to a remote location, or even better - to an svn server or something that supports versioning.
I want something which is:
1. free
2. does not overload the network too much but only send the diff.
3. works 100%
thanks in advance

I would say just backup the entire database. That will be an easier process, and you'll more easily maintain identity integrity in case you need to restore a backup.

i am required to back up certain rows from certain tables from a database. often the criteria requires joins and such. what's a good way to accomplish this? (i don't have to use mysqldump).
|
Complex Database Backup

It doesn't work that way.
What you need to do is set up a mini chroot jail for each backup host. It just needs to be able to run sh and scp (/dev only needs /dev/null entry).
Use jailsh as the login shell for each account.
Jailsh is a suid-root login shell that sets chroot jail to the directory marked by two consecutive slashes, drops root privs, and execs /bin/sh.

I need to run backups from multiple servers to a single account on another server. If one of the public servers is compromised, I don't want the other server's files on the backup account compromised.
What I need to do is only allow SCP to a specific directory, based on the ssh key of the incoming connections.
I know that I can set the shell, and several options on a per key basis in the authorized_keys file. http://www.manpagez.com/man/8/sshd/ (Scroll down to "AuthorizedKeysFile")
What I don't know how to set the internal-sftp command to only use a certain directory. I don't have root on the the machine, so I can't do the normal internal-sftp + chroot.

Depending on how up-to-date your data needs to be, snapshot replication seems like the best fit for you. It's not that difficult to set up and I believe that it's fairly common in scenarios like yours.

We recently moved from a simple DB recovery model (with daily full database dumps) on our SQL Server 2000 Standard database to full recovery -- combined with weekly full database backups, daily incremental, and transaction dumps every 10 minutes.
Our previous reporting DB instance (SQL Server 2005) was built from the daily backups which no longer exist. I can re-build the reporting database by loading the weekly dump, leaving it in recovery mode, and then restore the incremental backups. Unfortunately, this is not easily scriptable and doing this by hand sucks.
Taking additional full backups of the 2000 production database will ruin the incrementals (which are desirable for a number of reasons).
Is there a better way to do this? We can't do log shipping since we're only SQL Server 2000 Standard (eventually we'll upgrade to 2K5).

you have a couple of options with SBS, you can have additional servers in the SBS domain such as win2003 servers. You can only have a additional SBS server on the same domain for a limit of seven days, this is for migration situations.
In you situation I would have a additional win2003 server connected to the domain to act as a backup domain controller, then if your SBS systems goes down you can still do Active directory auth. and access any resources still on your network.
We create a base acronis image of the SBS server, then if anything goes wrong you restore the acronis image and then apply the backup file (We use NTBackup provided in SBS) to bring you up to date. using the combination of acronis and backups cuts down the time to recover significantly.
Hope this helps.

I have just joined a company with Server 2003 Small Business Server. The company contains only an handful of staff and needs a backup system.
I would like to restore a tape backup (including system state, Exchange server, etc) to a second server. The aim is to have a verified set of backups and be able to swap the servers if necessary.
Am I right in thinking that the second server could not be on the SBS network?

I think I found a way to do a complete migration...
Install a fresh version of MOSS 2007 on the new server (Server_B). Install the features and solutions you have on Server_A. Then use the SPContentDeploymentWizard which can be downloaded for free from CodePlex to make an export of all site content and import these on Server_B. Also backup custom databases needed by features and create these on Server_B.
I do have a almost completly equal server running now, some funky errors pop up now and then so I don't think it's the best way to do it...
Also, custom developed webparts need to be deployed manually to the new server, I didn't find a way to migrate these

The situation at the moment is that we have a sharepoint server which started out as a pilot but now actually runs as the production environment. The server on which sharepoint runs is an old machine which does not conforms the standard requirements so I want to move the current environment to the shiny new server.
I've red a lot about migrating the MOSS services, databases and content and stuff but to be honest I am kinda lost in a sea of information and I can't find the right method to do this, I've tried to install MOSS 2007 on the new server as a clean install, restored the databasses on the new server, restored the backup on the new server which I made with Sharepoint Central Administration, alas, I did not worked :-(
Lots of "Can't find this" and "Can't find that" errors...
It should be possible to grab all the data/sites/subsites/databasses/content/documents and everything else and restore that to the new server right?
Anyways, I was hoping for some step-by-step information... :-)

Cloning is perfectly acceptable.
You don't have to backup to tape... It can be done to a NAS for example, and with the proper security and setup, backups cannot be deleted by unauthorized people.

I am application developer and don't know much about virtual machine(VM).
however, our application is resided on a VM. frequent patch need be apply to fix/update this application. For diaster recovery, It was suggest to backup every thing on the server. so, once server is restored, no application need be re-installed and configured.
our network administrator thinks it can be done by cloning VM. but if we want to backup the clone to a tape. it would expose VM to backup drive. any one who can access to it can erase the VM and every thing woudl be gone. it is very risky.
I would appreciate it if you could let me what you think on this or any suggestion.

I've answered this on IRC so for completness:
The problem is the 'index="4"' part, which is an output-only element and thus not allowed by the schema on input. The rest of the XML is correct.
|
I am trying to create a backup of a given VM in »push mode« as described here. I have tried a lot of variations of the backup-xml but none passes the validation test. That includes the example posted here (the first one). Additionally I just ran that command:
sudo virsh backup-begin vm1 && sudo virsh backup-dumpxml vm1
which dumps the autogenerated XML of the backup job with default values. In my case that looks like that:
<domainbackup mode='push'>
<disks>
<disk name='vda' backup='yes' type='file' backupmode='full' index='4'>
<driver type='qcow2'/>
<target file='/home/xxx/.local/share/libvirt/images/vm1.qcow2.1684137281'/>
</disk>
<disk name='sda' backup='no'/>
</disks>
</domainbackup>
So I put that output in a file (bg.xml) and ran: sudo virsh backup-begin vm1 ./bg.xml which than again showed the error:
error: XML document failed to validate against schema: Unable to validate doc against /usr/share/libvirt/schemas/domainbackup.rng
Extra element disks in interleave
Element domainbackup failed to validate content
Any Idea what is going wrong here - since the auto-generated content fails validation I am getting out of ideas.

For a good solution, these are not very detailed information.
But the first hint:
The name of the folder is not IndexDB but
IndexedDB
... please note the additional ed.
Second item:
If the screenshot is from somewhere inside the IndexedDB, it must have been a subfolder within the IndexedDB:
=> The name of that folder is required.
The IndexedDB is stored within your user-profile. If you didn't change things (created a second user-profile, etc...) the name is "Default". So the whole path is
C:\Users\<username>\AppData\Local\Google\Chrome\User Data\Default\IndexedDB\<extension_identifier>\<your-backuped_files>
For Chromium it differs slightly:
C:\Users\<username>\AppData\Local\Chromium\User Data\Default\IndexedDB\<extension_identifier>\<your-backuped_files>
For more there are more informations required. — Such files can also be found outside the `IndexedDB' within your Chrome profile folder. Their names are generic, the specifier is the name of the folder they are stored in.

I have backup files that have the localStorage data saved in IndexedDB. These files look like this:
Due to system crash, the browser (Chrome) lost these files and I had to recover them from a backup system. Now I need to restore these files back.
Is there anyway to restore or even be able to read these files?
Any help will be appreciated. Thanks.

We are using SQL 2019. I wanted to create a Production database from my Dev database. So I took a full backup of the Dev database and restored it as Production - that part completed OK. But after it completed, I noticed that my Dev database is inaccessible and says (Restoring...). Why is this? I did not specifically ask to restore the Dev database. Also, it has been in this Restoring... state for some time now, a few hours, much longer than it took to create the Prod database. How can I get back to normal status?

First, perform the sanity check, connect to the database and run
SHOW archive_mode;
SHOW archive_command;
to ascertain that the settings are indeed as you think they are
To debug that further, you should resort to the log file. If the archive command is executed and encounters problems, those problems will leave a trace in the log. If you cannot see anything there, set log_min_messages to debug3, then you will get messages like
executing archive command "..."
whenever archive_command is executed.

here is my configuration file:
wal_level = replica
archive_mode = on
archive_command = 'touch /var/backups/test'
archive_timeout = 1min
Permissions are ok. Postgres user can write into the aproppiate folder. I also restart the database to make sure the configuration goes through.
When running SELECT pg_switch_wal() I can see data under $PGDATA/pg_wal/, however there is nothing in /var/backup. Any ideas?
Saw that older question which is very alike: https://serverfault.com/questions/221791/postgresql-continuous-archiving-not-running-archive-command in my case permissions are okay.

Take a look at the STANDBY option for the RESTORE statement. From the docs:
Specifies a standby file that allows the recovery effects to be undone.
NB - differential backups are based on the last full backup taken. So let's say that you take full backups on Sunday, differential backups every other day of the week and you're restoring every day.
Sunday, you'd restore only the full backup, bringing it online for read by specifying STANDBY with the restore
Monday through Saturday, you'd restore the latest differential backup on top of what you've already restored, again using STANDBY
When Sunday rolls around again, you'd need to restore the new full backup.
That said, you mentioned that you're on SQL Express. The database size limit is 10 Gb. At that size, how long does the restore of the full backup take? Is it worth your time? And even there, it's really "how much time are you saving the robot?" because you've already (presumably) automated the restore.

I'm periodically getting backups of an SQL database which I would like to restore in my machine. I'm able to do that with RESTORE fullDB WITH NORECOVERY; RESTORE differentialDB WITH RECOVERY;
However, I need to access the restored database in between, as the interval in which I'm getting the backups can be a few hours.
I tried restoring full backup WITH RECOVERY, but in that case I'm getting exception while restoring differential backup.
NB: It's not just one differential backup, it's real time backups taken every few hours. I'm using C# for executing the operations.
Any help is appreciated to solve the issue. Also, let me know if I'm barking at the wrong tree.
Instead of sending SQL database backups from client as .bak files, should I opt any other way to send the data?

Unfortunately, there's no native --pre-snapshot-script option for creating an EBS snapshot.
However, you could use a Lambda function, that is triggered based on a scheduled EventBridge rule, to trigger a script to be run before you then programmatically take the EBS snapshot. You'd need the SSM agent to be installed on your EC2 instance(s).
The idea is to use ssm:SendCommand and the AWS-RunShellScript managed document to run Linux shell commands on your EC2 instance(s).
You have a couple of options, specifically:
if you want to inline all of your 'special script' in your Lambda function, or download it from S3 during your user data script, or manually transfer it or ...
if you can run the Boto3 create_snapshot() (or the AWS CLI ec2 create-snapshot command) as part of your 'special script'. If not & you want to do it separately after doing send_command, you will also have to use the Boto3 ssm.get_command_invocation (or the AWS CLI ssm get-command-invocation command) to poll+wait for the command to finish, before you create your snapshot
What you decide to do is dependent on your specific requirements and how much infrastructure you want to manage, but the essence remains the same.
This could be a good starting point:
import boto3
def lambda_handler(event, context):
ssm = boto3.client('ssm')
commands = ["echo 'Command xxxxx of special script'"]
commands.append("aws ec2 create-snapshot --volume-id vol-yyyyy")
ssm.send_command(
InstanceIds=['i-zzzzz'],
DocumentName='AWS-RunShellScript',
Parameters={'commands': commands}
)

I want to make a backup of several EBS volumes attached to a EC2. There are Snapshots and AWS Backups available.
Issue is, before I can do a backup, I must execute a special script to freeze my application.
Why: it's somewhat im-memory, so this call forces all writes to disk to comlpete and also prevents new disk writes for a duration of a backup.
Is there a way to execute an arbitrary bash script before the backup job/snapshot?

You ask about monthly backups. In case you're okay with more frequent backups, you can schedule daily backups using heroku pg:backups:schedule (' quotes converted to " for compatibility with Windows):
Scheduled Backups
In addition to manually triggered backups, you can schedule regular automatic backups. These run daily against the specified database.
Set Up a Backup Schedule
heroku pg:backups:schedule DATABASE_URL --at "02:00 America/Los_Angeles" --app example-app
The --at option uses a 24-hour clock to indicate the hour of the day that you want the backup taken. It also accepts a timezone in either the full TZ format (America/Los_Angeles) or the abbreviation (PST), but we recommend using the full TZ format.
Note that backup retention depends on the database tier, varying from 7 daily backups and 1 weekly backup all the way up to 7 daily backups, 8 weekly backups, and 12 monthly backups. If you need longer retention, you'll have to retrieve your backups from Heroku and store them elsewhere.
If you really want monthly backups and not daily ones, you'll have to schedule backups some other way, e.g. using a cron job on another system.

The process I currently employ across my environments is:
Start with a baseline where STAGING and PROD are exactly the same. This you can achieve by restoring the latest backup(s) from your PROD environment to your STAGING environment.
As changes occur in DEV and need to be released to STAGING, create the appropriate release scripts to apply to STAGING.
When you need to refresh the data in STAGING, restore the latest backup(s) from PROD to STAGING again.
Optional: Run any post-refresh STAGING specific scripts that are needed. E.g. if you obfuscate any of the data, or change of the data to signify it's the STAGING environment.
Run any release scripts in STAGING, that haven't yet been released to PROD.
Over time your release scripts that were used in STAGING, should get used to release to PROD, which is what will help keep the two environments in sync.
Repeat steps 2, 3, and 4 at the frequency acceptable to your goals.
I have the above in a SQL Job so it's essentially a one click process, but my database is SQL Server on-prem. I also use a schema comparison tool called SQL Examiner to automate generating the release scripts I need, but not sure it's applicable to Azure SQL Database.

I have two databases in Azure SQL Database almost identical in their structure (unless one of the two is modified). I need to synchronize the data from the production database with the staging database, being able to make changes in staging without harming production unless I need to do a production restore (that's another topic).
In the case that there is no solution, I want to be able to make staging equal to production when my developers need it, is there a way to modify a database with a backup of another without having to create a new database (since you would have to modify the server name in the app)

When using the SaaS service on gitlab.com there isn't really a procedure to "backup" your data. Generally, you rely on GitLab to ensure your data is always available on gitlab.com
There is documentation for backup and restore processes but this applies to self-hosted GitLab instances only. (this is probably why you aren't able to figure out using the gitlab backup tools because they are intended for self-hosted instances only).
If you still want to backup your data that is on gitlab.com, one option might be to do a file-based export of a group. However, this procedure is deprecated and import support may be removed entirely in the future. Another option may be to "migrate" your groups following the group migration documentation onto a self-hosted GitLab instance, then backup that self-hosted instance using the backup and restore process linked above.
Other than this, it is also possible to export projects to create zip archives that can later be imported to GitLab. This will include repository data, issues, etc. You can't do this in a single operation for your whole group, but you can export each project in your group individually, if you want.

let's assume that duplicity works (it's not officially supported on windows in any way). never tried it.
say your backup data exists in the root of your external harddrive mounted as E:.
you want to restore the complete last backup into a folder C:\Users\john\OneDrive\Documents\temp\ .
two points
point it to your backup location properly. absolutely that would be /cygdrive/e/ or as url file:///cygdrive/e/
point to your target folder as folder ending with a slash / to signal that the backup is to be restored in there.
taking these points into account a command like
duplicity file:///cygdrive/e/ /cygdrive/c/Users/john/OneDrive/Documents/temp/
should work as expected.
NOTE: you don't need the action command restore as the order of arguments (url before local file system location) tells duplicity already that you want to restore.

My Linux machine recently failed and I am trying to restore my files onto a Windows 11 machine. The files were created using Duplicity (the external HD containing the files has hundreds of .difftar.gz and .sigtar.gz files as well as a '.manifest'). Having installed CGWin and the duplicity package, I traverse to my external HD in cgwin...
$ pwd
/cygdrive/e
... and attempt to restore the latest snapshot of my lost directories/files to a temp folder on my Windows 11 machine by running:
duplicity restore file:/// /cygdrive/c/Users/john/OneDrive/Documents/temp
At this juncture, the restoration fails due to a "IsADirectoryError" error.

I am trying to restore a DB2 database using an encrypted backup file. The backup zip file contains an .lst file, a .ddl file, over 3000 .ixf files, same number of message files and a folder with few .lob files in it.
I have tried using bind @ list_file grant public after placing the .lst file and .ixf files in the /bind directory. But the error was that .ixf files could not be opened.
Any help appreciated.

Regarding your specific question of:
Is there a way to "chunk" the stream so that it writes a new file/stream every X bytes?
Your best bet for adapting your current workflow to "chunk" your backup file would be to use GNU Parallel, using --pipe (and --block to specify the size each block of data to pipe through to each instance of aws).
|
We have a bespoke database backup solution that will be causing us problems in the near future. I'll explain.
S3 has a single file limit of ~5TB. Our backup solution utilizes xtrabackup with the xbstream option which is then piped into an 'aws s3 cp' command to store it in S3.
The interesting part of the script looks like this:
innobackupex {0} --host={4} --slave-info --stream=xbstream /tmp {5} | lzop | /usr/local/bin/aws s3 cp - {1}/{2} --expected-size {6} --storage-class STANDARD
Ignore the variables, they're injected in from a different part of the script.
The key thing to notice is that the xtrabackup xbstream output is piped-into lzop to compress it, then piped-into the "aws s3 cp" command to store it in our bucket as a multi-part upload.
We use the streaming paradigm to avoid local storage costs.
By now you can probably guess the issue by now. Our compressed backup size is rapidly approaching the 5TB limit, which will be catastrophic when we reach it.
So here's my plea. Is there a way that we can write compressed backups larger than 5TB to S3 from XtraBackup's xbstream to S3 without compromising our preference to not store anything locally?
I'm not too well versed in bash pipelines. Is there a way to "chunk" the stream so that it writes a new file/stream every X bytes? Or any other sane options? We'd prefer to avoid writing the raw backup, as it's 4x the size of the compressed backup.
Thanks!

There's no such parameters for BGSAVE.
An approximate solution is to use the SAVE config. Config it in redis.conf or use the config set command:
config set save "60 1000"
However, this config means after 60 seconds if at least 1000 changes was performed. It's not exactly what's you need: sync every 60 seconds or 1000 keys.

The problem is that the default output format of COPY, which is text, treats the backslash as an escape character, so it must be doubled. Use the csv format and set quote characters and delimiter to characters that do not occur in your data, for example
\copy (SELECT ...) TO '...' (FORMAT 'csv', QUOTE E'\u0007', DELIMITER E'\u0008')

I am trying to copy jsonb type of data into a file.
\copy (select myjsonbcolumn from mytable where time > timestamp '2021-05-01 00:00:00') to '/home/ubuntu/jsobdata.ndjson';
Now this jsonb data have \' within it. e.g.,
{"ID": "123","Body": "<p><a href=\"https://google.com\">Lorem ipsum</a></p>\n<p>Lorem Ipsum Lorem ipsum </p>"}
Now the above copy command adds an extra "" to it, which transforms into below
{"ID": "123","Body": "<p><a href=\\"https://google.com\\">Lorem ipsum</a></p>\\n<p>Lorem Ipsum Lorem ipsum </p>"}
Is there a way to notify not to add extra \? Because this huge data, more than 200GB and to replace those extra \ will take a lot of time via file processing

firstly, update Elasticsearch, and keep as up to date as you can. 8.X is now current and 7.X is only patched at the 7.16 level. but you're on 7.10, which was released in (late) 2020
second, you might want more than one slm policy. so something that you can use to take shorter snapshots that are discarded more frequently, versus monthly ones that you use for long term retention requirements
you can then look at making yearly snapshot repositories for the monthly snapshots, that means you can easily drop repos you don't need
|
We are using Elasticsearch v7.10 and want to add a snapshot policy to our cluster. We want to be able to restore specific indexes even after few years.
On the one hand it is recommended to take frequent snapshots (~every 30 minuets - Set up snapshot policy) but on the other hand it is not a best practice to accumulate thousands of snapshots, because it requires more memory on the master node and can destabilize it. It is recommended to include retention rules in the SLM policy (Snapshot retention limits).
I need to be able to restore at least 1 snapshot from each month in the last 7 years - is it possible? how does my SLM policy/ies and retention rules should look like?

Sure that will work. It has the advantage that you can compress the backup before sending it over the network. And if the transfer fails, you could resume it (using rsync). It has the disadvantage that it stores the full backup on the server.
Or you could backup from the "reserve" host using -h to specify the main host. This won't compress the data for transit (until v15 comes out) and can't be resumed if interrupted.
|
I am trying to figure out what is the correct way to create a full standalone backup which will be stored on a remote host(I should use pg_basebackup). I suppose that it should look like that:
pg_basebackup on the main host
Use scp to deliver it on a reserve host
Is it a right way?

I thought it was a simple python script, which could create a SQL database , then Install anaconda, use %%sql statements to recreate it,
Until I realized that they could be imported in SSMS, but there is something that I am not doing well to import it correctly, I understand that it is a problem of correctly parsing the file,
I appreciate any help, thanks!
Install extensions in visual code, anaconda and the necessary libraries for handling SQL in Python, but it all boils down to correctly importing the file created in SSMS.

Have you double checked the $storagename variable to just make sure it isn't actually null? Also, double check to see if the current storage account/container is tied to a RSV. Because, if it is, it won't allow you to run the Enable-AzRecoveryServicesBackupProtection cmdlet.

function Set-StorageAccounttoPolicy {
$storageaccounts= Get-AzStorageAccount | where {$_.StorageAccountName.StartsWith('p')}
Get-AzRecoveryServicesVault -Name xyztestvault | Set-AzRecoveryServicesVaultContext
$policy=Get-AzRecoveryServicesBackupProtectionPolicy -Name testpolicy
foreach($storage in $storageaccounts) {
$storagename= $storage.StorageAccountName
$resourcegroup= $storage.ResourceGroupName
if($storage.PrimaryEndpoints.File -ne $null)
{
$fileshares= Get-AzRmStorageShare -ResourceGroupName $resourcegroup -StorageAccountName
$storagename
foreach($file in $fileshares)
{
Enable-AzRecoveryServicesBackupProtection -StorageAccountName $storagename -Name
$file.Name -Policy $policy
}
}
}
}
I keep getting an error "Enable-AzRecoveryServicesBackupProtection : 'containerName' cannot be null.", but this storage account has not been assigned to a recovery vault or policy yet. How can I fix this?

The backup file generation is for persistence durability. When you don't need durability you can turn it off with this SQL statement:
SET FILES LOG FALSE
Or the database connection property, hsqldb.log_data
hsqldb.log_data=false
The data is still consistent with this setting but the changes will be lost in case of process termination.
See the guide http://hsqldb.org/doc/2.0/guide/deployment-chapt.html#dec_bulk_operations

So we are using HSQLdatabase as temporary storage to offload to disk for doing some calculation, we will be doing some bulk operations on merge statements(upsert/ insert or update)and size of database file in some cases reach as high as 70+gb. Is there a way to disable .backup file creation in HSQL db? we are fine with instances of DB corruption or node crash. Are there any properties that we can rely on for such use cases? I referred to Bulk Inserts, Updates and Deletes from document and will set up my properties accordingly.

As per the official docs,
A custom image contains only the OS, software, and settings for the WorkSpace. A custom bundle is a combination of both that custom image and the hardware from which a WorkSpace can be launched.
Seems like the image does not carry forward the personal settings like set wallpaper or any browser settings. I experienced this myself.
However, if you are worried about losing whatever configurations you have done if workspace becomes unhealthy, then you can use Rebuild or Restore option.
By default aws takes auto snapshots of root & user volumes of your workspace every 12 hrs.
You can read more bout this here
in terrible case where my images and my workspaces was accidentally removed
If your workspace is deleted/ terminated, no data can be retrieved.

I have an workspace in AWS workspace with a lot of configuration files, installed software and files with templates, shell scripts and code, so it's fully configured.
My problem is that when I try to create an image, I lost everything but the installed software. So anybody knows how can I create a backup of my AWS workspace to avoid to have to configure the desktop in terrible case where my images and my workspaces was accidentally removed?
Thanks.

When restoring, by default, SQL Server create the database file at the same place and name as the original backuped database.
If you are doing a copy of the database on the same SQL instance, this will raise an error, because files already exists. So you must move the file to another directory or give another name to the file, which is done by the MOVE option of the RESTORE statement.
Prior to that, you must ask which files constitues the original database, by executing the Transact SQL command :
RESTORE FILELISTONLY FROM DISK = 'the path and file of my sql backup'
Then you will have to follow the MOVE syntax, which is just:
MOVE 'logical file name' TO 'new path and/or new file name'

I am trying to copy 'Development' database and create a new database called 'Testing'.
For backup, I have used the below query and it worked fine.
BACKUP DATABASE Development TO DISK = 'Development15feb2022.bak'
For restoring I have used the below query which is giving some errors like 'Development.mdf cannot be overwritten. It is being used by database 'Development'.
RESTORE DATABASE Testing FROM DISK = 'Development15feb2022.bak'
I have done some googling and came to know that I need to use MOVE for logical file and logs.
But I am not sure if that applies to my scenario.
I want both Development and Testing working independently and storing each logs respectively.
Can anyone clarify please?

AWS is (mostly) region-based. This means that if you wish to communicate with a particular AWS service (eg Amazon EC2) in a particular region, then you must make an API call to that region. It can be done by specifying region_name when creating the client:
ec2_client = boto3.client('ec2',region_name='ap-southeast-2')
Thereafter, any actions performed on that ec2_client will be sent to the region that was specified.
For more examples, see: Python boto3- How to work on cross region
If you wish to make calls to multiple regions, you will need to loop through each region and create a boto.client() for each region in turn.
There are a few exceptions to this requirement for 'global' services: IAM, Route 53 and CloudFront. They replicate configurations between regions, so you can connect to just one region (typically us-east-1) to configure those services globally.

I am using AWS Lambda in Ireland region to create AMIs on daily basis for my EC2 prod instance. All my servers are in Ireland region except one which is in the London region.
For the Ireland region, I have the python script for taking backups, I just need to add the code in the same lambda for taking backup pf the London instance as well.
Since am new to both lambda and python, I m not getting where to add or what to add here.
Can Anyone help me here to enable backup for the London instance as well?
The current Lambda script is provided below.
# ec2_client = boto3.client('ec2',region_name=globalVars['REGION_NAME'])
ec2_client = boto3.client('ec2')

Need to enable backup replication feature in AWS RDS - oracle through terraform. So do we have any attributes from terraform side for that particular feature?

If you are specifically targeting ignroed files :
you can list the ignored files in your directory using :
git ls-files --exclude-standard -i -o
You can then use the output of this command to do something with the listed files.
For example, you can create a tgz archive :
# create a tgz archive :
git ls-files --exclude-standard -i -o | xargs tar -czf ../myenvfiles.tgz
and copy/extract that archive some place else.

My problem is that I often forget to backup or I need to use some ignored files in other devices, like .env ones, and sometimes it troubles my day because those files should not be commited, but at the same time I need those files updated if for some reason I need to use this repo in another device.
Is there any solution for that when I commit to my repo, some selected files can stored in a clould service like onedrive or google drive?
I tried to use my repos inside a folder that is synced with my clould, but the amount of files not ignored, like venv or node_modules, more hinders than helps me.
Thank you!
