Abstract
A storage control system and method for storing and retrieving data to and from a tape backup system that is located remotely from a primary host system. The primary system is coupled to a remote storage system for remote copy applications. The tape backup system is coupled to the remote storage system and operated at the remote site. Conducting control signals through the primary storage controller to the remote storage controller enables control over the tape backup system from the local or primary site. Data can be backed up to the tape system from the remote storage site which enables the local host to perform applications during the backup window. Data can also be restored from the tape system to the remote storage system and transferred back to the primary system via the communications link.
