Disk configuration for new (virtual) backup server?

[proxuser76]

Hi!

Dell R320 Proxmox 7.0 with 2x960 GB SSD as boot/VM and 2x2TB currently unallocated for backups.

PBS as VM on 2x960 and the 2x2TB dedicated for backups.

Is there any recommendation how to serve 2x2TB to the PBS? ZFS-mirror via Proxmox or directly as mirror-set via server disk-controller?

use pbs to set up zfs mirror and let os control it. disks in pass-through mode. this is the recommended setup.

Ah, yes that's a better alternative. PBS handling the ZFS mirror!

Many thanks!

And if you want better performance using HW raid would be fine too. Your BPS is already doing deduplication, compression and checksum verification in software so most of the nice ZFS features should be disabled anyway.

i was thinking more in terms of expanding storage in the future without shutting and handling everything on the os level but this is also a good point!
