(When the encryption
settings are applied)
Backup server
The Key Management Function Option applies the encryption settings from the remote panel to the tape
library and assigns one key called the master key. The encryption key that is automatically generated for each
data cartridge by the tape library is based on the master key, and this information is stored in a database in
the tape library.
During a data backup from a backup server, the tape library automatically assigns an encryption key to the
specified data cartridge, encrypts the data (plain text), and saves the data. The encryption process is
performed transparently during this time.
