I am using just one backup job to perform a full backup daily (weekdays only). Job works great except for Fridays. On Fridays, the job doesn't ever start. It is in a waiting state. But it ejects the tape. The local admin thinks the job is complete because the tape ejects when the job is complete daily. When the tape is changed on Mondays by the local admin, the job starts. Then, of course, it is running slowly because the server is in use during the business day. So I usually end up canceling the job.
I've tried using new tapes. I've also tried creating a separate job for Fridays, to no avail.
