I'd regard any interval between 1 hour and 24 hours as sensible for their 
respective setups; this largely depends on the ammount of mails and users your 
Zarafa installation handles, and the system load that you can spare for backup 
purposes.

If your system can handle an incremental backup every hour, that might well be 
the best choice. The size of the backups will be comparably small, as will be 
the risk of losing data. Due to its nature, Zarafa's brick-level backup will 
not have too much overhead for multiple small incrementals versus a single 
large one.
