are you saying , you would like to recover the tape with different master server which is in local site?

if yes, you would need to import the ecncription keys..

see the tech note below

below is just  from Tech note

KMS is the NetBackup Key Management Service. It can manage encryption keys for use by tape drives with built in hardware encryption.

Keys are created in the KMS database. When a backup to a tape from an encryption pool (pool name begins ENCR) is made, bptm requests the key from the key management service (nbkms) and passes it to the tape drive to encrypt the backup.

On restore, a key tag is read from the tape by bptm and the associated key is fetched from the nbkms service and passed to the drive so decryption can occur.

If you configure the "remote KMS master server" with the same keys as the local you should ready to go. 

If not already done, you should have stored  the passphrase  for Host Master Key (HMK), Key Protection Key (KPK), Key group in a safe place. Using thease passphrase will enable you to creater the same key group on the "remote" master server.

Good links from Nagalla yes

Assumption is the mother of all mess ups.
