I'm still pretty new to running a mail server, but one thing I've come to appreciate over the years is a good backup strategy. Since I have always run my own servers for practice and for personal use I don't have access to Enterprise backup solutions. Because of that I usually just fall back to scripts and tarballs and offload the content on a regular basis.
Suggestions and warnings are most welcome.
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)
