Check out the Cyrus Wiki page at:

Most people just make a regular backup of the filesystem using whatever 
tools they normally use.  The only "trick" is to export your mailboxes.db 
to a flat text file in order to back it up (which you should be doing 
periodically anyways).

It is probably not worth the downtime to actually shutdown Cyrus in order 
to get a consistent backup of the entire mail spool.  So what if a few 
files change while the backup is happening?  Unless you have really 
unreliable hardware, you'll create more downtime doing the backups than 
you'll ever prevent by having a consistent backup.  :)
