By default, when you erase a tape by using System Center 2012 – Data Protection Manager (DPM), it performs a long erase. If your tape drive supports short erase, you can use DPM to enable it to perform a short erase by following the instructions in this topic.
Enabling Short Erase
If your tape drive supports short erase, you can enable it on the DPM server by creating the DWORD UseShortErase under
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft Data Protection Manager\Agent.
Set the value of the DWORD to 00000000.
After this value is set, all erase operations on the DPM server will be short erases. To revert to long erases, remove this registry key.
|Though short erase is much faster than long erase, it does not completely erase the data from the tape. If you have a policy that all data from the tape must be erased and unrecoverable, do not enable short erase.|
