automatically encrypt virtual tapes when they are added to the pool.If you encrypt a pool, all virtual
tapes in the pool are encrypted when they are created. If virtual tapes exist in the pool when the
pool is configured for encryption, you can specify whether they should also be encrypted.If virtual
tapes exist in a pool before the pool is encrypted, you can choose whether to encrypt the existing
virtual tapes.
You can also decrypt virtual tapes after they are encrypted.
