Since reinstalling Win2003 & Backup Exec 9.1.4691 on my media server, any job that duplicates a disk backup to tape will not run. The job just sits there with the status "Loading Media". I was able to run duplicate jobs before the reinstall. A job that duplicates a tape backup to disk will run.
I am fairly certain that BE has been installed and configured with all the same options I had previously. The only differences I know of are:
1. My original install had SP1 and hot fixes up to 39 installed. The current installation includes hot fixes 40,42,43,45 and now SP2.
2. I had stated experimenting with using Media Sets for overwrite protection. My defaults when installing BE were for no protection.
My first thought was that my tape was in a protected media set but that's not the case. I can run backup & erase jobs directly to the tape. I have checked the Media and Device status and they seem fine. The fact that a backup to tape runs would imply the Device and Media are ok.
I have tried to duplicate disk backups of the media server's C: drive, BE backups of a remote server, and even a backup of a remote server created using Windows Backup. All just stay in the queue and display the job status of Loading Media.
I can see several threads in the 9.1 support forum that describe similar problems but no solution. One from Dec 3,2004 seems to describe exactly the same behaviour I am getting.
