To successfully perform the configuration backup, the following prerequisites must be met:
/SM590000All nodes are online.
/SM590000No independent operations that change the configuration can be running in parallel.
/SM590000No object name can begin with an underscore.
13.3.1  Backup using CLI
You can use CLI to trigger configuration backup manually or by a regular automated process. 
The svcconfig backup command generates a new backup file. Triggering a backup by using 
the GUI is not possible. However, you might choose to save the automated 1AM cron backup 
if you have not made any configuration changes,
Example 13-1 shows how to use the svcconfig backup command to generate an ad hoc 
backup of the current configuration.
Example 13-1   Saving the configuration using CLI
IBM_Storwize:ITSO-V7k:superuser>svcconfig backup

The svcconfig backup command generates three files that provide information about the 
backup process and cluster configuration. These files are dumped into the /tmp directory on 
the configuration node. Use the lsdumps command to list them (see Example 13-2).
Example 13-2   Listing the backup files in CLI
IBM_Storwize:ITSO-V7k:superuser>lsdumps |grep backup
187 svc.config.backup.bak_7822DFF-1
208 svc.config.backup.xml_7822DFF-1
209 svc.config.backup.sh_7822DFF-1
210 svc.config.backup.log_7822DFF-1

Table 13-7 lists the three files that are created by the backup process.

Important: Ad hoc backup of configuration can be done only from the CLI by using the 
svcconfig backup command. Then, the output of the command can be downloaded by 
using SCP or GUI.
Note: The svc.config.backup.bak file is a previous copy of the configuration, and not part 
of the current backup.
File name Description
svc.config.backup.xml This file contains your cluster configuration data.
svc.config.backup.sh This file contains the names of the commands that were issued to 
create the backup of the cluster.
svc.config.backup.log This file contains details about the backup, including any error 
information that might have been reported.
