It would be nice to add a backup section to the documentation.
Live backup is supported with Cyrus, though running "dump" on a live
filesystem is only to be done with care. We use vxfs on Solaris and
snapshots and have been happy with it.
The databases are backed up by Cyrus 2.1 every checkpoint period into the
db.old directories. At least one of those directories should contain a
clean copy of the berkeley db databases.
In general, mailboxes can be restored if the message files are around---you
can always delete the cyrus.* files (losing flag state) and run reconstruct.
