Hi,

I am having a similar problem, the clue to your problem is you say the
"administrator console is always logged on"... which causes NTBackup to fail.

I found KB Article KB927073 which talks about blank log files and the fact
that the console is logged in.

Is there anyway around the issue? That is my question. If I create a
Schedule account does this avoid the problem? I am Going to give it a go to
see.

But does anyone at MS know of a way of fixing the problem as described in
KB927073 ?

Thanks

Ian

I just solved this problem on my server but here is the catch. I was
trying to back up mapped drives. When you are not logged in the mapped
drives are not available. I put net use in the batch file and it
worked. I hope this helps someone figure out their problem. How I
figured this out was I ran the backup from the remote machine and
tried to backup to the removeable drive on the server which was shared
out. This time instead of a blank backup log I got one that read
"media not available". Then it dawned on me that the mapping to the
removeable drive was not available when not logged in. I placed net
use in the batch file on the server and now the mapped drives are
backing up.

Hi Sal,

Thanks for that. My backup only consists of the local C: drive and the
server is just a file and print server, no exchange or anything like that.
Just plain vanilla backup...which "should" work ;-)

You must be careful when mapping shares in a scheduled jobs.
UNC coding is fine but if you map drive letters to shares then
you are likely to run into trouble.

Don't use mapped drives. Use the UNC name for the drive/resource.....
