To backup Cyrus you should backup the following directories
/var/lib/imap
/var/spool/imap
as well you should run the following command as root prior to backup
su - cyrus -c "ctl_mboxlist -d" > /var/lib/imap/mboxlist.txt
this command will create a text file containing a list of all your
user's mailboxes, this is done in case you are restoring to a different
version of cyrus/bdb so you can read it back into cyrus. If you do not
have a list of the mailboxes, cyrus will only restore whatever is in
your inbox and nothing else.
I was able to do the backups as the machine was running cyrus, but YMMV
depending upon your traffic.
Hope this helps,
Mike Petersen
