How can I backup the entire Gallery (photos and videos) to my desktop computer? The Gallery on my Android device seems to show all the photos and videos, whatever the method to get them could had been (camera, whatsapp, bluetooth, and so on).  

I would like to backup them all, but all I have found on the net refers to one nagging method, consisting of syncing it to some cloud (DropBox, for example) storage. This is painfully slow, and I prefer to store my multimedia on my desktop computer, for example by pluging the USB cable or transferring it via USB storage device, SD card... etc.  

But the only way to backup the entire gallery to my computer I have found is just the manual method of copying each involved directory that could contain those files. This is like some sort of nightmare, due to:  


There are multiple possible directories that I must (nearly) guess, depending of the program that got the photos/videos: camera seems to be at DCIM, WhatsApp at whatsapp, another directory for bluetooth ... etc.
There are two storage drives: the phone itself and the SD card. So the job must be done twice.
Some Windows system (my Windows 8.1 at least does, I don't know why) don't allow concurrent file transfers via USB cable, so I must seek&amp;start the first transfer of files (say DCIM), wait until it finishes, start the second (say bluetooth) and so on.
Restoring such backup requires rebuilding the exact directory structure on the phone, but I could prefer to store all the photos and videos on the same folder on my desktop.


Isn't there a more simple way?
Both solutions involving Android's native or additional software (freeware preferred) are accepted.
If not possible, I could accept a solution involving to send the entire gallery to any cloud/internet and recovering it on the desktop.
I don't prefer cloud backup because of high priced internet plans in my country, and the answer by Lord Ralf Adolf didn't work for my device somehow. Ultimately, I had to find a solution which is supposed to be no pain only gain. Here we go with one mentioned below.

Notes:


The solution requires a USB cable, MTP enabled (available in Android 4.xx and 5.xx) in Android device, (devices with USB Storage Mode would work as well), and Windows 7/8 in PC. 
If MTP somehow doesn't work in your PC, you've no access to USB cable, or your device doesn't have MTP feature, then you may very well host a server on your Android device, preferably a WebDAV server. See my answer here for  know-how.
Tested the solution with Android 4.2.1 and Windows 7.




What this answer would achieve?


Works well with/without USB Storage and MTP support in Android device.
Backup multiple directories easily.
Can backup two or more storage drives by choosing the following solution only which would require repeating the instructions, or (following+linked) answer which would make it happen in one-go.
Fully automatic once final instruction is executed; no need to do manual copy for each file/directory.
Copies exact directory structure so that you don't have to worry during restoring the data.
Needs no Internet connection (other than to download some required software here).




A bit of explanation before going to the kernel

The problem with most of the media backup apps (I noticed) for Android is that they don't really preserve or care for the exact directory structure, which means you can mine images from anywhere in the Android but you can't really mirror the directory tree for saving the file in your destination storage, i.e. (analogy)

copy F:/DCIM/Camera/DSC11*.JPG C:\Users\Firelord\Desktop\Test\ 


is easily possible and available by many Android apps and Windows softwares, but not

copy F:\DCIM\Camera\DSC11*.JPG C:\Users\Firelord\Desktop\Test\DCIM\Camera\DSC11*.JPG


The same holds true for many Windows Explorer alternatives for Windows 7/8 including FreeCommander, Multi Commander, Explorer++, XYplorer and other tools like SmartCopy. 

(Note that I tried the listed ones but could not find the desired functionality with ease (auto copy with tree). Let me know (to edit) if your experience differs.)



Anyhow, the trick was to find a software for Windows which allows to take media backup(not disk/media imaging) with synchronization feature. Three such candidates that I tested and found easy(GUI) are SyncToy, FreeFileSync and PureSync. (All are free for personal use.)

I recommend FreeFileSync and the instructions for its usage are mentioned below.

Instructions:


Download FreeFileSync(free).
This program might not create Start Menu entry. For a 64-bit Windows 7, the program's directory location is C:\Program Files\FreeFileSync and a relative one would be for 32-bit Windows 7. Execute the FreeFileSync.exe (right-click &rarr; Run as Administrator).
(On my machine this program freeze out for few seconds during its startup but eventually stabilizes and doesn't behaves alike.) The default screen for v7.0 would look like:


Connect your Android device into PC using USB cable, and choose MTP for data transfer.
In FreeFileSync, you would see two fields with name Drag &amp; Drop at the top of left and right pane. They hold the location for the source and destination storage. Edit them:


For left pane click Browse &rarr; My Computer(left side) in the opened window &rarr; select your device (say HTC One; under Portable Devices) &rarr; choose either Internal or External SD card of Android device &rarr; Select Folder(at the bottom).
For right pane click Browse &rarr; My Computer(left side) in the opened window &rarr; select the backup location (say D:\Backup) &rarr;  Select Folder(at the bottom).



In FreeFileSync under the Menu bar, go to Actions &rarr; Filter settings. Here you can include the filetypes and exclude the folders from mining or backup. E.g. If I want to backup only .jpg and .png image files from my Android but I want to avoid those in the Android, Data, any .folder or folders that were created by some apps and includes irrelevant files with such extensions, then my filer would be:


Note that the filter is not complete in the picture as opposed to text in the answer 

Tweak as much as you want since it's easy. I seriously advise excluding Android folder. Click OK when done with custom filters. (Note that I've not added but you may add video extensions too like .mp4, .mkv, etc.)
In the Menu bar, go to Actions &rarr; Synchronization settings and choose any of the variant available. For the first backup I prefer Mirror to backup all the filtered files. Click OK at last.


In the Menu bar, go to Actions &rarr; Start comparison -- this will show the filtered files in left pane (source) and files available in right pane (destination; would be empty for a new backup folder). (You can always switch the panes by clicking the blue &lt;> icon available between the two panes.) An e.g. would look like:


In the Menu bar, go to Actions &rarr; Start synchronization -- this will (as obvious) synchronize the two folders based on the setting you chose in Step 7. An e.g. of process, and completion would look like:






We're good to backup anything here. Note that for restore the steps (as obvious) would be same but the locations at left and right pane would differ. Also, during restore, my phone freeze out a lot (the reason could be a low class SD card in device or altogether a program issue itself, IDK!)

Issue with, and solution for, multi-storage Android devices

One issue that a multi-storage Android device user would've noticed is that you'll have to repeat the instructions to backup both External and Internal SD card. 

This can be avoided by using a file server in Android. See Method#1 or Method#3 in my answer here. Just make sure that the file server should have its root directory at /storage so that in the FreeFileSync all storages (would be listed as folders now) can be mapped for backup. 

I tried and it worked well! 

Status: Objective Completed



I could cover SyncToy and PureSync here, but the latter freeze out the whole time whenever I click any option and about the former: it's intuitive and very easy in "exclude filters" but doesn't give much flexibility in synchronization variant (I would've ended up deleting images in device due to lack of such, but was stopped somehow. :) ) 

I think the objective can be achieved by using find and rsync tools in combination on GNU/Linux.

Let me know other options if you come to know any, or technical mistakes in my answer.
