Why not write directly to tape rather than going through an extra step
and requiring extra disk space?

You need to backup all of /var/spool/imap and /var/lib/imap. Some parts
are less critical, but they are small anyway so you shouldn't try and
leave out parts of it.

From cron as user cyrus, ctl_mboxlist -d >/var/lib/imap/mailboxes.txt

That gets a bit more fun. Our policy is to do restores for users at the
folder level (assuming a user error restore -- a dead disk restore is
easy, just restore everything). We create a RESTORE folder under the
user's mailbox, set a quota on it, then restore all the message files
and cyrus.* files from the folder to be recovered into that directory.
Then run reconstruct on user/joe/RESTORE, and let them do what they want
with the messages there. The RESTORE folder is automatically deleted 2
