Once the files make it to my Windows TSM server, they eventually get migrated to tape. They are medical images, and can never be deleted. My RAID is only 400 GB, so once it hits the watermark it deletes, after it is already on tape. Now, when the client requests a file, how does the TSM server know where it is on tape? I ask because the original has been deleted off of RAID. Does the DB record this or something?
