Unable to automate NT Backup

[vbajock]

I have been trying to set up NTBackup to back up my Exchange Information Store to a file on a hard drive. It works fine when I run it manually, but when I try to run it using Windows scheduler I get the message:

*************
Replace Data:

The requested media is not blank. It was created by another application.

Do you want to continue? ?
*************


Needless to say, the interruption of an automated job by a request for user input sucks rocks, especially when I am not even using a tape drive. The only thing I can find on it is MS article #295159, which deals with tapes. I am not using a tape, so this information is useless. Has anyone got a workaround on this?

I have not backed up to a file, but have backed up to tape. the first dialog box gives you a choice to append to media, or overwrite. Which ever is selected, I would choose the other. It seems simple, but who knows, it may work for you.
