备注
The DataSourceType element determines whether the data source defined by the Location element contains a local data source or a remote data source. For more information about backing up and restoring remote partitions, see Backing Up, Restoring, and Synchronizing Databases (XMLA).
The value of this element is limited to one of the strings listed in the following table.
Value
Description
Local
The Location element defines a local data source. If this value is used, the Restore and Synchronize commands use the information defined in the Location element to update the data source, retrieved from either the backup file specified in the File element for the Backup command or the database specified in the Source element for the Synchronize command, identified in the DataSourceID element of the Location element.
This value allows objects that use relational OLAP (ROLAP) storage, after being restored or synchronized, to use a different database for their data and metadata.

注意：
ROLAP data, such as data in dimension tables or writeback tables, is not restored or synchronized. Only metadata for ROLAP objects is restored or synchronized.
Remote
The Location element defines a remote data source. If this value is used, the Restore and Synchronize commands use the information defined in the Location element to restore or synchronize remote partitions, retrieved from either the backup file specified in the File element of the Backup command or the database specified in the Source element for the Synchronize command, to the remote instance identified in the DataSourceID of the Location element.
