Encryption of Data Cartridges Stored at an External Location

For disaster recovery, encrypted data cartridges can be stored at an external location and, when needed,
brought back to read the data on them. Even if a data cartridge in storage is lost or stolen, the encryption can
prevent data leakage.
Once a data cartridge in storage is inserted into its original tape library or one with the same master key, the
data can be read from the library without setting the key again.
Once encryption keys are exported, even if the tape library becomes unavailable such as in the event of a
disaster, data on the data cartridge can be read by importing the encryption key to a tape library with a dif-
ferent master key.
