Using a custom script allows you to restore snapshot backup images taken using storage devices that are not supported by DB2® ACS.
You must have one of the following authorities: SYSADM, SYSCTRL, or SYSMAINT.
A snapshot restore operation restores a snapshot backup. You must use a custom script for that restore operation if your storage device does not provide a vendor library.
During snapshot restore operations, the protocol files that were written during the snapshot backup are read. As well, a new protocol file is written for the restore operation to show its progress. If the restore operation is successful, the protocol file is deleted; if the operation fails, you can use the protocol file to help investigate the cause of the failure.
A restore operation restores the latest image that matches the specified time stamp. For example, if there are two images for the time stamp 20121120, one taken at 201211201000 and one taken at 201211202000, the last one is chosen.
