Actually a good idea. But this requires a documentation update.

For sure. But before wasting time, I wanted to know beforehand what your opinions are 😎

I prefer bind mounts over volumes (personal opinion) so you have my vote

Backup/restore would then just be simple host commands cp / mv..

Doesn't that mess with permissions / ownership metadata on files?

I prefer bind mounts myself, but a common issue I can run into with containers is the container writes the files with different uid/gid (mostly only an annoyance if you're non-root), or you configure some files from the host side and if the container lacks permission to read/write the file it gets upset.

Regarding the referenced issue, kinda seems odd to backup clamav bloat, depending on the age of the backup when it's restored, I'm not sure how worthwhile that would be to retain? This is still a nice improvement anyway :)

Might be worth adding to the FAQ how to restore?

I also wanted to be a bit more explicit about the option for compressing to gzip. I'd suggest --zstd with tar.zst but not sure how wide the support for that is.

I think creating a .tar.gz is the most widely compatible archive for Linux and we should use that:)

Yeah, that's why I was reluctant with my preference to use zstd (which is definitely better when available).

I'd still prefer the more explicit option of --gzip however, since this is a FAQ item and the user is probably going to copy/paste anyway.

I prefer verbosity, too. Always hard for future contributions to look up / follow along if a bunch of short options is thrown together using a tool a contributor might not know. As most will copy/paste it anyways it should not be a big deal

Yes. We will use the long option --gzip :)

@docker-mailserver/maintainers feel free to edit/add docu yourself to this PR 👍

This was just a first attempt. I was too tired to continue yesterday.

Documentation preview for this PR is ready! 🎉
