Docker configs destroyed after update [resolved!] (lemm.ee)

Hello selfhosted community, something weird just happened to my setup while running a routine update.

I'm running docker containers on a couple Debian LXCs through Proxmox, and a regular apt-get upgrade just wiped all my configurations. Somehow it seems to have gutted my databases and deleted the compose.yml files without a trace remaining. Thankfully all my data seems to be intact as far as I can tell.

Did I royally mess something up in all of my configurations or in doing the update? This has never happened to me before. Thankfully I have a backup for the configs that's about 6 days old, but it's still extremely annoying. Any hints? Thanks

That's pretty weird, where were the files stored that went missing? Just in your home folder?

Definitely recommend setting up regular daily backups, you can use the built in proxmox backup system, or run whatever tool you want inside each VM/CT.

The files were on a mountpoint, completely separate drive. This has also been the case for all the previous times I ran an update, though I did recently move these files to a different drive mounted the same way. I got some sort of permission wrong maybe?

Will definitely set up a better backup system as soon as I can

Very odd, I think something else is going on not related to LXC/Proxmox. I've got LXC containers with external mounts and internal storage and haven't seen any data loss over the years they've been running.
