Just FYI: A few weeks ago we had a problem with a Server running Zarafa. The
only usable backup was a full and lots of incremental. The Zarafa support told
me, that it is not recommended to have more than X incremental after a full. I
can't remember the exact number, but i am sure it was less than 10. So having
running an incremental every hour might not be the best thing to do. Though our
restore with more than 100 incremental backups worked just fine.
