A question on LXC portability

[bellocarico]

I have limited resources: single Proxmox server installation and a PC running Ubuntu.
I'm essentially redeploying my legacy server based on ESXi 6.5. In the past as a backup I used VMWare workstation installed on my PC (Ubuntu) and (via nightly backups) I could in case of emergency run the VM/s on my PC.

Now I'm looking for a similar poor-man backup solution between Proxmox and My Ubuntu PC.
The question is rather simple: how "portable" are LXC?
I mean if I create an LXC on Proxmox is there any easy way I can run this on Ubuntu (managing the thing via e.g. LXDUI), does the LXC need any conversion/modification? How about the proxmox provided debian11-image I'm relying on for LXC?

I know it's completely not a great idea but for simplicity sake (since the LXC have little workload) I'm even considering installing Proxmox in a Vmware Workstation VM and use that as an LXC backup.

Sorry lots of questions, any hint/guidance would be greatly appreciated.
Thanks!

Proxmox created LXC containers my run in other environment (as e.g. ubuntu) too, but you cannot rely on this. Moreover it is the question which kind of backup you make; directly compatible they will be only if you failover environment is also Proxmox VE. That means the solution installing Proxmox VE as VM in VMware is the easiest way. You may also consider to install Proxmox VE at your PC? It's based on Debian and you can install also a desktop environment on top of it. Possibly existing VMware virtual machines can also run in Proxmox VE (understands vmdk virtual disk format).
