Another benefit of the image/snapshot is that it would eliminate the
huge burden that the file-level backup has on you TSM DB. For example;
if that filespace has 1 million files that results in 1 million entries
in the DB, since the image or snapshot is a single object there is only
a single entry in the DB.

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.
