Abstract
A method and apparatus for backing up and restoring data to a database is provided. During the backup, data blocks are copied from a database to a storage medium without the contents of the data blocks being analyzed during the copy. Data indicating the initial configuration of the data blocks is also backed up. During the restore, the data blocks are copied from the storage medium back to the database. The information within each copied data block is analyzed to identify any location dependent information (e.g., pointers). All location dependent information is updated based on the initial configuration and the new configuration to cause the location dependent information to reflect the new configuration.
