Tape Recycling

If Tape Recycling is enabled, old keys for the tape volume are purged from Cisco KMC when the tape is relabeled, and a new key is created and synchronized to the Cisco KMC. This setting should be selected when you do not need the old keys for previously backed-up data that will be rewritten.

The default setting is Yes. Setting this option to No is required only if tape cloning is done outside of the SME tape group.
