You can call this operation to restore a database.

Database can be restored to an existing instance or restored to a new instance.

  • Restored to an existing instance: restore some databases in the old instance to the existing instance which can be the old instance or another instance in the same region. If the database name is repeated, you must use a new name. The old databases cannot be restored in overwrite mode.
  • Restored to a new instance: create a new instance, and then restore all or some databases in the old instance to the new instance.
    • If you specify a database name, the new instance only restores the corresponding database (partial restoration).
    • If you do not specify a database name, the new instance restores all the databases in the old instances.
Note This operation is applicable only to the instances of SQL Server 2012 and later versions.
