restic as a proxmox disaster recovery tool ?


Sep 30, 2021
Hi to you all ! I've tried restic before and didn't get very far with it, but now I want to try again because there was some points I've really liked about it (fast, reliable and relatively easy to manage). The issue is ... I'm not confident enough in my linux-fu skills to know exactly how I could use it a bit farther than a fast backup tool.
Ideally, I would like to use restic in these scenarios :
- to create periodic full system backups
- to be able to use restic as an easy and fast disaster recovery tool

Here's the options I use to take my snapshots (for now) on a NFS share :
restic --compression max --one-file-system --verbose -r /opt/backup backup / # used in a cron twice a week
restic forget --keep-weekly 1
restic prune
Could you please share your advices and thoughts, or your script (if it's not too long ^^'), about how you're using restic (or any close enough tool) ?
Should I exclude some paths or --one-file-system is enough ? Or maybe I should add some paths specific to proxmox ?
And according to you, what would be the fastest and more reliable way to restore a snapshot in case of an emergency ?

Thanks for your help !
