i used nt backup to backup my company data to hard drive it was working fine but now backup is not happening and the backup log file is always empty.i used to schedule it to happen at 18:00 hrs but keep on failing even if i run the backup job manually nothing is happening and the log file is empty...
First off, thanks heaps. I've been seeing an intermittent failure of my Exchange 2k3 box to successfully complete its full backup job with the following Event error: The backup has stopped with error -521 and, in the backup log, "First Storage Group is not a valid drive or you do not have access"....
