Backup plugin - use folder other than 'omvbackup'

cubemin · 28. November 2020

I use the OMV Backup plugin to clone my system to a dd image periodically. The backup files are, of course, stored in a subfolder 'omvbackup' under my selected destination shared folder.

I'd like to use a more descriptive folder name. How do I change this - I'm thinking editing the /usr/sbin/omv-backupcommand in the scheduled backup job with a custom argument should do the trick?

You can't change it. If you edit the backup script, it will be overwritten on plugin upgrades. Why not just create a new shared folder that has a more descriptive name?

Sure, I could do that I guess (though then I'd still have to live with a subfolder 'omvbackup').

But are you saying that just updating the plugin overwrites the existing scheduled job? I wasn't talking about editing any scripts, just the job itself (within the web GUI).

Oh the horror lol.

No, updating the plugin does not overwrite the existing scheduled job. But there is nothing to change with that job. All it does is execute omv-backup. There are no arguments. So, you would have to edit the script and that edit would be overwritten by a plugin upgrade.

LOL @ "Oh the horror." OK, OK. Fair enough.

Thanks for answering my question

Ok, since it was an easy change, I added the ability to change the directory name and filename prefix by setting variables in /etc/default/openmediavault. 5.2.2 is in the repo now.

You're awesome.

Do I insert the following two lines exactly as shown while simply changing the names inside quotes?

Code

OMV_BACKUP_DIR_NAME=${OMV_BACKUP_DIR_NAME:-"omvbackup"}
OMV_BACKUP_FILE_PREFIX=${OMV_BACKUP_FILE_PREFIX:-"backup-omv"}

No, just add the following to /etc/default/openmediavault. You don't have to change both. You can one or both.

OMV_BACKUP_DIR_NAME="new-dir-name"

OMV_BACKUP_FILE_PREFIX="backup-prefix-name"

Jetzt mitmachen!
