Best way to backup cyrus system (lots of inodes!)

[Robert Scussel]

On a smaller scale, we use amanda to do nightly backups of the mail 
spool, and we have successfully recovered after mails have been deleted.

With one of our clients, we use standard NetBackup to do nightly 
backups, which works just as well.

As for up to the minute backups though, don't know a good solution which 
doesn't sacrifice performance.
