This is more a ceph question then a Proxmox question I guess.
But I want to backup images in my Ceph pool for offsite backup so preferably incremental how would one do this?
Can I take a snap shot like
then maybe for each day
Transfer the first initial and then everyday sync with
And transfer only the diff files.
But when can you delete the Initial snapshot and the 'older' diff file? (otherwise snapshot will take a lot of space on cluster)
And afterwards when can you use merge-diff to create a 'good' file on the other side?
Anyone with good bash skills like to program above (if at all possible).
