Tape Retention Question
I am using Backup Exec 2010r3. Under my Media Set properties, I have Overwrite Protection Period set for 9 days and the Append Protection Period set for infinite - allow append. Under the properties of my Daily backup, I have "Append to media, overwrite if no appendable media is available. I have a four week tape rotation (a five day work week, so 20 tapes total) and my department needs to keep 90 days worth data on the tapes. The issue it seems I am having is that my tapes are filling up and they do not seem to be deleting old data from the tapes. I have looked at some of the tapes and they still have data from June of last year on them. I have five scratch tapes set aside, but again, I have to keep 90 days worth of data, so overwriting my scratch tapes is not possible. Does anyone have any suggestions. The Overwrite/Append options are a bit confusing, but from what I have read, I am not the only one.
