Greetings,

I have a NUC running a PVE server with1 Plex LXC, 1 Ubuntu VM, and 1 PBS VM. I have an NFS datastore on my NAS that PBS backs up to.

I have a nightly backup job that runs in "Stop" mode, and it backs up my Plex LXC and my Ubuntu VM. It keeps 3 copies at a time. I did have my PBS VM checked to backup as well until I realized it broke my backup jobs because it was being shut down during a backup (duh, should have seen that one coming). I have since unselected that.

I like the idea of getting a full backup, and one that only adds in size to what was changed since the last one. I'm not super in love with my LXC & VM shutting down every night and having downtime, even though it's only a few minutes. Is there a better way to approach this? Maybe 1 full backup a week where it stops and shuts down, and then the rest of the week does snapshots?

Also, I have a daily cron job running with prox_config_backup that backs up to a separate NFS mount on my NAS. I wanted to make sure I could restore PVE to it's current state should I need to, and this seemed like the best/easiest way to do it.

Is there something similar than prox_config_backup, but for PBS? Maybe a separate job that just snapshots the backup of the PBS VM as opposed to shutting it down? Basically if my NUC crashes and burns, I want a quick and easy way to get it back to the previous state as soon as I can with as little reconfiguration as possible.

Thanks for any help or ideas for me.

Hi!
Yes, the 1 full backup once a week + snapshot every day is a nice strategy.
Regarding the config backup, all the configuration files for PBS reside in /etc/proxmox-backup/ [0], so you should be good to go if you backup these.
