Backup VM in Virtual Machine Manager, and running containers in VM

[Reguna]

(Crosspost from Reddit)
Hi,
I have a DS220+ with extra 16GB of RAM.
I am planning to create a no-GUI Debian VM and run K3s on it. It will also act as a Proxmox cluster voter (with qdevice).
(I have two other servers that also run Proxmox and VM with K3s on it)
I will try to limit workload of the NAS; the other servers will do most of the heavy lifting.

My questions:

1. Can I run containers inside a VM? Will there be significant performance degradation?
2. How do I create a scheduled backup task of this VM? (preferably using native packages and no payment required)

You can yes but the performance will depend on how well the VM is running ofc. With that CPU I would reserve my expectations.

How do I create a scheduled backup task of this VM? (preferably using native packages and no payment required)

VMM has built-in protection using snapshots (local ones). Remote snaps (replication) is a paid option for a secondary unit.

Backup as such (apart from snaps), is not an option, other than exporting the VM and then backing it up (not an automated process).

Thanks for your reply.

I am looking at the Active Backup for Business package, it supports Debian and may suit my need

Ofc, and using ABB once you connect it to your hypervisor. But keep in mind that Proxmox is not supported, so see if you will be able to get your VMs inside ABB for backup that way.
