I need a solution
We are running backup jobs on two removable SATA drives - one for the full backups and one for two weeks worth of diffs. After two weeks, we swap in two new SATA drives, and repeat. The full backups are set to expire after two weeks, and the the diffs are set to expire after one week.
The problem is, when we swap the original drives back in, the expiration dates for the full backups are extended to two weeks from the date we reconnected the drive, instead of two weeks from when the backup was taken. Why is this happening, and is there a way to prevent it? It's not problem for me to manually delete the old backup sets, but I would prefer the process be automated.
