How far away is your product from being able to support Firebird 2.1?
If it was possible to get it to work, you could use NBackup. NBackup
could do a full backup (level 0) daily, a level 1 every hour and then
a level 2 every 15 minutes.

That approach should get a pretty good compromise between performance
and closeness.
