The Database Manager supports the use of external backup tools for complete and incremental data backups as well as for archiving log backups.
Start the process for restoring the database instance from the Database Manager CLI. The naming conventions for external backup media enable the program to recognize and start the external backup tool.
You have configured your SAP DB software installation for the external backup tool you want to use (see Integration of External Backup Tools).
When you restore data, NetWorker requires the exact name of the relevant backup pipe. This means that the media group must be configured in exactly the same way it was when you backed up the data. The backup media must also be in the same order in the media group.
First determine the external backup ID for the required backup (Retrieving the External Backup IDs, Displaying the External Backup IDs). The Database Manager uses this ID to identify the backup that is to be restored.
The number of media in a group of parallel backup media must correspond to the number of media used to create the backup.
If a deadlock occurs when you restore parallel media, you must use the Database Manager to import the backup in sequence (that is, each individual medium in the media group).
Proceed as described in Restoring the Database Instance.
