While doing work, I found data being backed-up that should not have been (sensitive data). We have CommVault do the scheduled backups to local hard drive, and copy the data after 15 days (7 days, 2 cycles) from the hard drive to our external backup tape magazines.
My question is a simple one--how can I erase that folder from all backups in the last 35 days (time we have been backing up this data)? Furthermore, how can I find out all the data on each tape (I have a list of all the tapes that contain data from this server in the referenced time period.
Is there any way to erase all traces of this file?
