Using Encryption
Once BlueScale Encryption Professional Edition is configured on your library, configure your
backup software so that data to be encrypted is sent to a partition that has encryption enabled
and has been assigned an encryption key. Encryption during backup is transparent—it
happens automatically.
Restoring data is also transparent. If the encryption key required to decrypt the data is not on
the library, the library displays the moniker of the key to import. Once the key is on the library
and applied to the partition with the media, data restores without requiring additional steps.
Restoring Data
on page 115 contains information about data restoration.
Professional Edition Overview
Professional Edition supports multiple keys on the library simultaneously. Each partition that
is enabled for encryption uses one key to encrypt data backed up through that partition. To
streamline the reverse process of decryption, you can further configure the system to
associate multiple monikers with a single partition. When you need to restore data, the
BlueScale key management software looks at the keys you’ve assigned to the partition for
both encryption and decryption. If it finds the right key, that key is used. If a key is required
that isn’t assigned to the partition, the software displays the moniker of the key it needs to
decrypt and restore the data.
Best practices recommend that you track keys associated with data on the tape, so that you
can readily decrypt and restore data.
