Abstract
Unique key aliases are generated for tape libraries. According to one embodiment, a first library identifier associated with a first tape library, which does not conflict with a second library identifier associated with a second tape library, is generated. One library identifier is associated with each of the tape libraries. A unique key alias, which does not conflict with any key aliases associated with the first tape library and does not conflict with any key aliases associated with the second tape library, is generated based on the first library identifier. Tape data is encrypted based on a data key that is identified with the unique key alias as a part of writing the tape data to the first tape library.
