Proxmox Virtual Environment 9.1 available
(www.proxmox.com)
Proxmox VE is a complete, open-source server management platform for enterprise virtualization. It tightly integrates the KVM hypervisor and Linux Containers (LXC), software-defined storage and networking functionality, on a single platform. With the integrated web-based user interface you can manage VMs and containers, high availability for clusters, or the integrated disaster recovery tools with ease.
I think it's highly recommended to do it the way you're doing it, especially for the DR aspect of it, using the builtin tools of Proxmox like replication and PBS.
I do it that way and I've had nothing but success with recovering a borked update or other problems in my containers.
