[PVE-User] Proxmox and ceph - incremental backup proposal

[Fabrizio Cuseo]

Hi all.

Can you evaluate this proposal in case of ceph with proxmox for incremental backup ? 

If i would like to have this backup plan:

1 day of month:  full backup
every day:  incremental
15th day of month:  differential (from full backup)
every day: incremental from differential

We could:

1 day of month: delete all previous snapshots
                create a snapshot, execute the full backup
every day:   create a snapshot
             use rbd --export-diff from previous snapshot to the last snapshot
             execute the backup of this exported diff (that is the incremental)
             delete the previous snapshot (not the 1st)
15th day:    create a snapshot
             use rbd --export-diff from 1st snapshot to the last snapshot
             execute the backup of this exporte diff (that is the DIFFERENTIAL from 1st)
             delete the previous snapshot (not the 1st)


Is this possible ? 

Regards, Fabrizio
