Recovery from an unsuccessful restore operation

A restore operation can be unsuccessful either because an error was encountered when trying to restore an object or because the operation was interrupted. If the object existed on the system before the restore operation, it might be damaged by the unsuccessful restore operation.

An object is not restored when an error is encountered. The error is either recoverable or not.

Restore operation error is recoverable: If an object cannot be restored and the error is recoverable, the following situations will occur:

• A diagnostic message is sent to the job log for each object that is not restored. The message ID can vary, depending on why the object was not restored.
• Each object that is associated with the errors is not restored. However, other objects not associated with the errors but involved in the same restore operation are restored.
• Only the save and restore status information for the objects that were successfully restored is updated.
• A count of the number of objects successfully restored and a count of the number of objects not restored are sent to the user in a diagnostic message.

Restore operation error is not recoverable: If the error is not recoverable, the following situations occur:

• Diagnostic messages are sent to the job log for each object.
• The save and restore status information for each object is not updated.
• A diagnostic message that identifies the error condition is sent to the user.
• The restore command ends immediately. No other objects are restored.
