Abstract
A method of restoring data in a computer network system wherein a plurality of client systems have access to a storage pool coupled to an associated storage area network (SAN) includes: requesting a restore wherein each of the plurality of client systems may participate in the restore; and coordinating access to the data stored in the storage pool by tracking a plurality of data portions of the data to be restored and by blocking access to each of the plurality of data portions that have been restored by one of the plurality of client systems to avoid duplicative restoration efforts. A master restore table may also be constructed to assist with coordinating access to the stored data. A computer network system configured to coordinate a restore request where a plurality of client systems may participate in the restore is also provided.
