How to backup maildir

I have been thinking, and reading, on how to back up my mailserver. I
have not found any approach that seems ready to use.
I have run years without any backup, but would really like to have
something in place. I figure I can attach a USB drive and backup to
that, then from there rsync to something elsewhere. Further if that USB
drive is a full mailserver image, I actually have a 'hot backup' where I
only have to put the backup drive into a system and boot up at the last
But this means properly copying all of /home/vmail and probably
/home/sieve plus the /var/lib/mysql
Are there good tools that nicely does this? Or do I choose a time late
at night (only I am sometimes in non-US timezones) to shut down all
services and just use rsync?
And stopping services itself is thought provoking. What if Dovecot,
amavis, mysql, or whatelse is in the middle of writing out a mail file
what happens to that file and restart.
Just scary stuff and, in part, why I have never tackled this in the past.
thanks for all feedback
