Hi Everyone, We're in the middle of buying a new tape drive system to replace our aging LTO2 and LTO3 system. We also will be leveraging disk to disk backups, but that is a side issue. The question I was curious about is how long do each of you keep a copy of your data on tape, before re-using the tape? Also, is the back up window decided by you and/or a Dean/ Commitee?
