We are running Veritas Backup Exec 9.1 for Windows Servers. We have a Dell PowerVault external DLT drive. When backups are made on clean tapes, those tapes cannot be overwritten. In the job log it says.. "Overwrite Protected Until 12/31/99. On our other backup devices, the media says "Overwrite Protected Until 12/31/9999"
I am assuming on the tapes I am having problems with, Veritas thinks the overwrite period has expired (12/31/99) and will not let me overwrite those tapes.
My question is, how do I change the overwrite period to 12/31/9999?
