Abstract
Replication requests are initiated in a virtual tape emulation system by storing a replication request in a persistent storage area that is shared between a virtual tape emulator and a control station. When the control station sees a pending replication request it initiates a request to a replication control to replicate the affected file or file system to a backup storage array. The control station deletes the replication request when the replication task completes. Deletion of the replication requests from the shared area is taken by the virtual tape task as a signal that replication has successfully completed, and can be reported to the mainframe.
