Mailboxes are in Maildir format. Any good backup tips? Had success with version control?

I suggest rdiff-backup: a great tool that keeps an actual sync
(rsync-based) of the data-directory and the metadata (delta) in a
seperate directory to restore data from any date.

Alternatively, you might want to take a look at bacula, which was faster
in most cases (development seems to have stalled, but there is a fork I
have not had time to take a look at: bareos). However, I liked the
rdiff-backup way because I can restore files via scp or rsync (most of
my requests were like "please restore from yesterday") or if I want to
restore data from a certain date I can use rdiff-backup from command
line (bacula is much more complex, and you need the admin tool to
restore files)
