- I’m backing up LXCs, like I’d back up a VM. I don’t back up Docker containers, just their config and volumes.
- I don’t think anyone is doing that. We’re talking about installing Docker in LXC. One of the Proxmox rules you can live by is to not install software on the host. I don’t see the problem with installing Docker in an LXC for that reason.
- I’ll snapshot an LXC before running things like a dist-upgrade, or testing something that might break things. It’s very easy, so why not?
- I back up my LXC that has Docker installed because that way it’s easy to restore everything, including local volumes, to various points in time.
OK so when you said “no, it isn’t” you meant “yes, sometimes it is”?
