I'm currently testing a new appliance setup with Nextcloud which includes the ability to use containers as a default for everything, if your container can be moved to an empty VM, nothing gets deleted as I didn't touch it. I would be really happy if this helped.
Could you please elaborate a bit on the appliance?
I use a home-grade PC with Ubuntu LTS on which there is nothing except for:
- docker
- borg (backup program)
- wireguard (VPN)
- sshd
I then copy /etc/docker from backup, mount some external disks with the data (either backed up or not for things I do not care about), reboot and I am done.
My recovery lasted one hour from starting the download of the ISO to being back on line.
