Most people seem to be using LVM snapshots. We have a custom backup thing at FastMail. Building a better backup/restore for Cyrus has been on my todo list for a long time, but I keep not getting time to work on it :( Basically I run a simple master/replica setup and use LVM snaps in combination with rsnapshot for disaster recovery. Those snaps were archived with rdiff-backup later then. Another idea might be imapsync. But depending on how big your cyrus spool it will take its time. It's more a tool for moving mails between imap servers. I think a cyrus-replica setup is a good and stable way to handle a crash. Any backup based methods will lose changes in between the cycles.
