ABSTRACT:
In a network that includes a first database located on a first client and a second database located on a second client, a user or administrator initiates a restore operation. A dynamic mirror relationship existing between the first and second clients is terminated and a backup version of a database which the user or administrator wishes to recreate is identified. One of the first or second clients receives information concerning the location of the backup version of the database, as well as the role designation of the database at the time the backup operation was performed, from a restore server. The backup version of the database is retrieved from the storage location and recreated on each of the first and second clients, and the dynamic mirror relationship is reestablished between the first and second clients.
