You can erase spare media from the tape library.
You can perform one of the following erase spare media operations:
-
Quick erase
Data remains on the media, but it cannot be read or restored. The OML (On-Media-Label) is overwritten with a new OML to indicate the erased status. Use this option to logically remove data quickly and when you must keep the media onsite.
-
Full erase
All data is physically erased from the media. The process takes longer to complete than quick erase. Full erase is suitable in the following scenarios:
-
You want to move media to an offsite location.
-
You must remove all data to meet compliance regulations.
-
You want to delete sensitive data.
-
You can erase media from the media list of a library or at the library level.
