Best approach to dual-boot Proxmox VE and Proxmox Backup

[emma.makes]

I'm currently working on redoing my homelab and want to introduce Proxmox Backup. I have a Proxmox VE server hosting a couple of containers running 24/7. I have a second Proxmox VE, which I only boot every now and use as a testbed. Now I'm wondering if I could dual-boot the second testbed server with Proxmox VE and Proxmox Backup, for occasional, manual backups of the containers from the main Proxmox VE.

The second, testbed Proxmo VE does have two SSDs, so I reckon one could have Proxmox VE and the other Proxmox Backup, then I could boot into either depending on the task ahead.

Does anyone have experience with such a setup? Would it be more reasonable to host Proxmox Backup nested on the testbed Proxmox VE?

...if I could dual-boot the second testbed server with Proxmox VE and Proxmox Backup

That would probably work, because... why not?

But for what advantage?

I would (and I did) just install PVE (you have that already) and then add PBS to the running system, in parallel. Add the relevant repository (https://pbs.proxmox.com/docs/installation.html#proxmox-backup-no-subscription-repository), run apt update && apt full-upgrade and install PBS (https://pbs.proxmox.com/docs/installation.html#install-proxmox-backup-server-on-debian).

At the end you can visit https://ip:8006 for PVE and https://ip:8007 for PBS

Have fun!

Oh that's a fantastic idea, if that works as described. Thank you!
So I'd be able to backup the containers running on the same machine, on Promox VE, to an external storage. I'll have to test that out on my spare Proxmox VE.
