Was not one of your questions "How can I set up and confirm schedules for 5 seperate daily backup jobs?" and others?? This was answered correctly as stated before everything in the manual and backup up functions are located in Maintenance > Backup in the GUI.
Additionally from your question regarding:
"However, your response refers to the "local backup" operation. I am seeking assistance with the TAPE BACKUP operation." "The pages and fields that you mention are there, and are applicable to the "local backup". They appear to have nothing to do with the tape backup." "Is there somewhere that I can confirm that the scheduled backup job has been submitted and applied?"
All are relate to the Backup function within the NAS-XSR Enterprise. This was answered correctly as all our backup functions and Tape functions are located in the Maintenance > Backup of the GUI. Only the function of the Local backup status will be shown in the Status > Logical Volume of the GUI near the bottom of the page you will see "Function: Local backup status & Function: Local restore status".
As for independent "TAPE FUNCTIONS" or Tape Backup functions outside of what we have been using with the NAS-XSR Enterprise since the first version, then we do not have this specific Tape Functionality that you are referencing (other then what I mentioned rewind, eject or erase), also there will be no more updates for Tape functions as the NAS-XSR family is EOL. We will be improving this with future releases of DSS.
