Hello,
I have a VM with two hard disks, one I want backupped every 10 minutes, and the other only a daily backup is fine.
Is it available a backup configuration making it possible?

So far, the only workaround I did see is to have two distinct VM with its own disk each and configure the backups with the appropriate schedule, but I'd like to avoid to split that VM.

Any hint is appreciated!
 
Hi,


In Proxmox, the backup setting works for the whole virtual machine, not for each disk separately.


So, it’s not possible to back up one disk every 10 minutes and another disk only once a day from the same VM.


The only way to do this is to create two VMs, each with one disk, and set different backup times for each.


Another option is to use Proxmox Backup Server and make your own backup scripts if you need more flexible schedules, but that requires some technical setup.
 
Yep, so far the 2 VM is the only way.

Dunno if a more granular backup may be useful to other people, as separating the backups of the VM settings and the single VM disk with option to do both (the actual behavior) or one of them.
