I am currently backing up Exchange using GRT in backup exec 12. I finally got it working correctly and it ran several days with no issues. I was backing up the data to a USB 500 Gig HD with no problems. We purchased a new external 1 TB USB drive and the above stated issue began to happen. The only thing I am backing up is our 1st and 2nd information store and that equals to about 170 gigs.
Before the HD swap, I would get two .IMG files with one bfk written. Now, I get at least 50 bkf files and the backup sits on "loading media" after an extended amount of time. I have the media set to "Allow Append" and "Do not allow overwrite" but have tried changing those options with no success. I have attached a screen shot which shows the backup folder. Thank you for any help that is provided.
