I have a request from the money men to figure out what it costs us per GB to store and backup files to tape for customers. We currently are running an external Scsi Raid enclosure with a Raid 5 array. To back files up we use Veritas Backup Exec connected to an external LTO2 tape library. Has anyone else ever had to come up with these numbers and have any suggestions on the best method? Again just to clarify, I'm trying to come up with OUR cost of storage so that we can base a price for our customers off of that. Thanks!
