File permission error while trying to run NTBACKUP

[Guest NetTech]

Whenever I try to run an NTBACKUP job, it backs up C: and D: drives fine,

however it always fails on S: drive with the following error - "S: is not a

valid drive or you do not have access to it"

 

When I browse My Computer, S: IS a valid drive, and I DO have access to it.

It has about 6-7 folders in it and I can open, browse and write to each

folder in it. I also verified that I have full permissions to the foler.

 

I've pasted below the NTBACKUP LOG and also the EVENT LOG

 

Thanks for any help,

Re: File permission error while trying to run NTBACKUP

 

Although you don't say so, I suspect that you're running ntbackup

as a scheduled job. Scheduled jobs run in their own environment

and just because you have drive S: in your own session does not

mean that drive S: exists for the scheduled task.

 

You should use UNC coding for scheduled jobs instead of drive letters.

Re: File permission error while trying to run NTBACKUP

 

Pegasus, thank you for the quick reply. The job was running as a scheduled

job, but during my troubleshooting I ran it as a manual job and got the same

results. The S: drive is actaully a partition and not a share, therefore I'm

not able to use a UNC path.

Re: File permission error while trying to run NTBACKUP

 

When running this backup job (either manually or under

the Task Scheduler), embed it in this batch file like so:

 

@echo off

echo %date% %time% Start of task > c:\test.log

echo User=%UserName%, Path=%path% >> c:\test.log

dir S:\ 1>>c:\test.log 2>>&1

dir C:\ > c:\test.txt

copy /y c:\test.txt S:\ 1>>c:\test.log 2>>&1

ntbackup /.. /.. /..

echo %date% %time% End of task >> c:\test.log

 

Now run this batch file, then examine c:\test.log in

detail. I suspect that everything will become clear.
