The shutdown backup_server with nowait command shuts down the Backup Server, regardless of current activity. Use it only in severe circumstances. It can leave your dumps or loads in incomplete or inconsistent states.
If you use shutdown with nowait during a log or database dump, check for the message indicating that the dump completed. If you did not receive this message, or if you are not sure whether the dump completed, your next dump should be a dump database, not a transaction dump. This guarantees that you will not be relying on possibly inconsistent dumps.
If you use shutdown with nowait during a load of any kind, and you did not receive the message indicating that the load completed, you may not be able to issue further load transaction commands on the database. Be sure to run a full database consistency check (dbcc) on the database before you use it. You may have to reissue the full set of load commands, starting with load database.
