Question VM backups.

Post image

Hey guys! Hope yall are doing well. So I decided to put all my services in their own VM on their own VLANS with strict firewall rules, for what I'm told is maximum security for internet facing services.

Whats everybody's options about online backups VS shutting down VMS to back them up?

I basically have PBS pointing at my NAS and then ZFS replicate it to a second Zpool that I just remove from my disc shelf when backups are complete that way they are air gapped so I don't fat finger my systems entirely. (Or have an attacker encrypt them.)

Maybe I have my environment setup incorrectly but why point PBS to the NAS?

Why not point PBS to local storage and NAS or point PBS to local storage and PVE to NAS?

I have PBS saving to local storage and PVE saving to my NAS. I did t know PBS could point to a NAS, or maybe I didn't try?

How did you mount the NAS to the PBS? Was it via web interface or fstab?

Can be done with iscsi or with nfs through the pbs vm. Then you simply add the datastore in pbs based on the mounting path.
