Dovecot has an interesting feature called Alternative Storage, might be

No need to do that with Dovecot's alternative storage, it is completely

I admit I've never used it, and it does require you to use dbox storage
format, which has one downside - losing the index files will cause data
loss (message flags and other meta data), but as long as you are using
reliable storage, especially if you are using something with
self-healing powers (like ZFS or BTRFS), it shouldn't be an issue, and
dbox (both sdbox and mdbox) are very performant.

Sounds like that should be more a server side feature - unless you are
talking about the end user being able to do the backup/restore operations.
