If you are experiencing "Object Not Found" errors with your Yosemite Server Backup, please reset your Superloader. 

1. From the Linux Command Line (GNome Terminal or Konsole) # service YTBackup stop
   
2. Physically turn off the Superloader via the rocker switch on the rear of the unit
3. Unplug the tape drive and wait at least 5 minutes
4. Plug the unit back in and power on the Superloader
5. After the POST completes and the Superloader display reads "System Ready", from the Linux Command Line # rescan-scsi-bus.sh
6. Start the Yosemite Service # service YTBackup start
   
7. After the Superloader has initialized, open the Yosemite Backup Administrator (from the Server-RM Desktop).  Confirm normal operation.
