If you want to use the description field of a tape in Backup Exec to identify the backup media set. You will notice once tape is rewritten or formatted the description is lost.
These fields can come in handy for example when you are trying to identify tape 1 as week 1 or as month January.
To change this behaviour, follow this procedure:
- Use regedit to locate the following key HKEY_LOCAL_MACHINE\SOFTWARE\Symantec\Backup Exec for Windows\Adamm.
- within the ADAMM key create a DWORD value called: PreserveMediaDescriptions.
- Set the value to 1 to maintain the media descriptions during overwrites.
- Restart the Backup Exec services.
