In my experience, there is no need to stop any service. We've been pulling 
backups from the live imap spool for three years now without stopping cyrus 
(we actually ran into problems with starting/stopping way back then). The 
worst that can happen is that a few mails will not get backed up as they 
appeared or disappeared after rsync has made its file list. Those mails will 
get picked up in the next round. We're running four incremental snapshots per 
day that way and up until now it seems to work perfectly fine.

Hence, it really depends on what you need to accomplish: If you have a *lot* 
of mail coming in at any given time and if you need your backups to be 100% 
accurate all the time, you might have to think about other ways. If you can 
live with the scenario I described above, you get away with not stopping 
cyrus.

Cheerio,
