Hi there!
I serve a CephFS via Samba to my hosts and would like to backup the shares to my PBS running a raidZ2.
Is there an elegant and efficient way of doing so? Maybe even incremental?
What are your recommendations?
You will have to use the proxmox-backup-client. See the Documentation on how to use it.
PBS is storing backups in a deduplicated way. What this means is that, if data did not change between backups, it will not be stored twice, but the new backup will reference the already existing data.
