Is your feature request related to a problem? Please describe.
I try to evaluate how OpenArchiver would work for archiving and searching a 20 year archive of my private mail. One thing I searched for was what needs to be backed up to a) be save in case the homelab server gets destroyed and b) move it to another place.

I already saw a lot of mention that it's "just files in a directory", but the docker compose stack contains a pg, which is a different beast to backup (and e.g. to update to a new PG version in time). It would be interesting to know (and have it in writing in the docs and as a design goal) if one can rebuild the data (assuming a single user) with just the mailfiles on the volume.

Describe the solution you'd like

The docs contain a description what needs to be backed up and preferable an example how to do it.
It would also nice to document if and how the whole mail archive(s) can be restored form the plain mail folder(s).
