I'm actually running Backup Exec while logged in as Administrator. Could it be that the Backup Exec Service Account doesn't have permissions to the file?
And yes, I've tried moving the file to another folder and even another drive...all of them failed.
Is this batch file to be run on the media server, or the remote server being backed up? The default option is to run it on the server being backed up, in which case it must be on the server.
If you want the batch file to be run on the media server, the option is under Tools, Options, Pre/Post Commands.
