NT BACKUP

I have the following backup script scheduled to run on the my server at night:

ntbackup backup c:\winnt c:\Goldfax_NT DS \\KNSSHPR IS \\KNSSHPR /t /v /b /d "Email server backup"
ntbackup eject

However it seems that the last line (ntbackup eject) does not eject the tape. I have watched the script run and though it backs up fine, and though the eject line runs the tape is never ejected. I tried putting a WAIT command after the backup completes but this didn't work.

Any ideas why and what I can do?

The ntbackup uses a generic scsi sense for the eject tape. It is a flip of the coin if it will work with your tape drive. most older units will work some of the new ones I have tried do.

Thanks for this. Still looking out for an answer that might help me go about the problem.

Cheers!

Check out this info from the technet CD about the ntbackup eject command.

first this is the line I quickly noticed:

NTBackup Eject /tape:1

I saw this in the concepts and planning section, chapter 6, and there is a really good artical for all the switches and commands.

Hope this helps.

Oh, BTW where the /tape:1 the number 1 represents the drive number, so you may have to try a different number if you have several drives.

Thanks

The problem is that not all NT Backup tape drivers support tape eject and not all drives support software eject.

There may be a command line switch that might work - to save time in troubleshooting, you can just open a command box and enter thevarious commands on the command line until you find one that works and then include that in the batch file rather than running the full batch file every time while you're experimenting.

In some cases, I have had to obtain a utility from the tape manufacturer that forces an eject. I just put the proper command line in the batch file and when Backup completes, it calls the utility and ejects the tape.

regards!
