Hi,
depends on the usage - I have on some systems an raid-1 with 2TB-Disks for the system (100GB) and all other space for backup.
I use links to get an folder for each node and use rsync to copy the content to the other node.
Like this:
Code:
/backup/dump -> /bckup/proxmox-a
ls /bckup
proxmox-a
proxmox-b
proxmox-c
The daily backup is done by bacula - the pve-backup is for desaster recovery and special use cases only.
