Hey i was looking for some input regarding my current and potential backup strategy.

Setup:

I have 2 Hosts in a Cluster with a QDevice hosting multiples VMs und LXCs

Currently:

I currently backup all my VMs and LXCs to a NFS Share on my NAS-VM.

The NAS-VM is backed up to the local disk of its host and then synced to an external drive.

The most important files for my Docker-Containers are also backed up daily to another external drive.

Potential Idea:

Setup a PBS-VM and backup all VMs and LXCs to a local Datastore in the PBS-VM,

This Datastore is then synced to a NFS-Share on my NAS-VM and i backup the PBS-VM with all the other Backups inside of it the same NFS-Share. The PBS-VM-Backup would then be synced to an external drive

My thought process was that as long as my NAS-VM, PBS-VM or external PBS-VM Backup are available i can either restore my PBS-VM on a new Proxmox Host and use the local Backups to restore all the others or create a new PBS-VM pointing it to the NFS-Share and access all the Backups that way.

I know that its not a 3-2-1 setup but thought this would give me quite alot of flexibility to restore my setup while using the compression and utility of PBS.

Ideally i would sync the Datastore to another PBS-Server but I dont have the means to setup at the moment.

So am I missing anything important or would this setup work?
