I know about the helper_script/backup_and_restore.sh. But I’ve a 500GB mailcow environment and producing every day a 500GB backup isn’t a good solution.
So, my mailcow vmail is stored on a folder on the system itself. When I have a deeper look into backup_and_restore it only makes a tar of that volume within docker. So I could just use for example borgbackup to make incremental backups of that folder.
Is this a recommended solution or is there another approach?
With best regards
