Abstract:
A virtual tape engine migrates a virtual tape volume between filesystems. A source virtual tape volume is copied into the virtual tape engine, and a target virtual tape volume is generated. Data associated with the source virtual tape volume may be modified to generate the target virtual tape volume. For example, compression or encryption state may be modified. Migration may be triggered automatically in accordance with a migration policy. The source virtual tape volume remains accessible during migration.
