The backup was working fine for many months with this same configuration and setup.  Then for a few random evenings it would say failed to mount media as it does above, but everything backed up as far as I could see.  Then it would randomly work fine again.  But lately it has been consistent failures. It goes through backing up the system state before it stops and says its finished, but with errors.  Can anyone help point me in the right direction?

How old are your backup tapes?   Have you run a cleaning tape in your tape drive lately?  Try a new tape (and I mean BRAND NEW) after running a NEW cleaning tape through your drive.

Good luck!

The tapes are less than a year old and we have a tape for each day.  We also have a monthly tape that has been used 11 or 12 times that produces the same result.  We also just opened our 2nd cleaning tape as a test to try that as well.  Results have been the same.
What happen to the new tape? Have you tried to backup with the new tape? By the way, you can try to format and relabel the used tape before trying to reuse it.

The brand new cleaning tape had no effect on this as I suspected.  I also tried to format an old tape and re-label it.  Nothing changed.  

I have put in a purchase order for 1 brand new tape to see if that helps at all.
Brand new tape and still the same results.  As I sit and watch it go through it's process every file and system state seems to get copied to the tape.  It is all there for me to restore - but every time it generates the failed error and gives all Failed status in the Backup report.  I would just like to know why it does this.  There is nothing unusual in my event log that is not in the backup log already.

Ideas??
You can try to install the following hot fix from Microsof to see if it helps:

http://support.microsoft.com/?id=831664

There are lots of thing relevant to the failure that ntbackup could not tell you specifically the error. Do you check your data size to be sure the tape has enough room to cover the backup. I guess I have a list of question to clarify this before looking in the failure in system state backup.

How many tapes do you use for one backup?
What size of the tape?
How big is data (C, D, istore, system state....)?
Did the backup run OK before the patch? (doesn't always mean the patch impact it, but you can uninstall the patch to see if it helps)

K

If you read my first post I have already applied that hot fix.  The backup would not even run before that.  It would not mount the media at all.  After the hot fix, it worked like a charm for many months.  Then this error became random and sparatic.  Now it is constantly failing with this message.

The tapes are 36/72.  Using hardware compression with only a tiny bit over 40gb to backup.  I've never noticed a problem with space.  I will run a much smaller backup sometime today as a test to see if it's space related.

Well it turns out Inkevin was right.  The data was not compressing enough to fit onto a single tape.  I excluded C: and just backed up my data on D: no problem.  Then I tried just my C:/, system state, istore, etc and it worked as well.  I wonder why the logs did not generate an error state to say this?
I guess because you can always append more than one media. But yes, MS should be more specific on its error log. I agree.

K
Previously it would ask me to append on to another tape.  I didn't want to have to change any tapes the next morning to finish the job or get a changer device so I excluded some non-crutial files until it fit onto 1 tape.  I guess we out grew ourselves on this matter.

Thanks for the help.
You are welcome!
