Restore systems

A restore recreates database server data from backed-up storage spaces and logical-log files.

A restore recreates database server data that has become inaccessible because of any of the following conditions:
  • You need to replace a failed disk that contains database server data.
  • A logic error in a program has corrupted a database.
  • You need to move your database server data to a new computer.
  • A user accidentally corrupted or destroyed data.

To restore data up to the time of the failure, you must have at least one level-0 backup of each of your storage spaces from before the failure and the logical-log files that contain all transactions since these backups.
