I'm wondering if a Fastback type (block level incremental image) backup might 
be the answer.  Backing up changed blocks might be faster than trawling the 
filesystem, and the ability to mount a point in time image would provide you 
with file level restore as well as DR image recovery.
Just a thought.

Snapshots/image backups?

Don't think about the backup, think about the restore RTO/RPO.

What kind of restore scenarios do you have, how much data (in time) can you
afford to lose and what is your acceptable restore time?

Will you ever need to restore individual files? I'm not familiar with
Blackboard but if you don't then the fastest way back would be a snapshot,
either in LVM or hardware, or a Windows image backup.

Depending on the application then it might even be that you need to do it this
way to get a consistent backup and keep metadata/filedata in sync.
