About using volume pools to manage WORM media
You can dedicate volume pools for WORM media. This method lets a WORM-capable tape drive back up and restore standard and WORM media. NetBackup uses two reserved volume pool prefixes to indicate that the volumes in a pool are for WORM drives, as follows:
WORM (uppercase letters) denotes WORM media.
WENCR (uppercase letters) denotes WORM media on which NetBackup should encrypt the data.
For more information about encrypting data on your media, see the NetBackup Security and Encryption Guide.
When you create a volume pool for WORM media, specify one of the reserved prefixes as the first characters of the pool name. NetBackup examines the volume pool names to determine if they begin with a reserved prefix. For readability, it may be beneficial to use an underscore character after the prefix, for example WORM_.
Note the following cases:
If the drive contains WORM media and the media is in a WORM volume pool, NetBackup writes the media as WORM.
If the drive contains WORM media and the media is not in a WORM volume pool, NetBackup freezes the media.
If the drive contains standard media and the media is in a WORM volume pool, NetBackup freezes the media.
If the drive contains the Quantum media that has never been used or all of its NetBackup images have expired, NetBackup uses the media.
