ABSTRACT:
A method and system for retrieving data that is stored on a backup or secondary storage system located at a remote location to a local storage system. Restoring of backup data involves the transferring of a point-in-time copy of primary system data from a secondary storage system to the local system. The point-in-time copy is created on the secondary system using an asynchronous remote copy scheme. The point-in-time copy that is restored may be either an entire volume or portions thereof.
