I have set-up a father/son rotation system. Monday - Friday I run a Differentail backup and have assigned 4 slots(tapes) to this job. On Saturday I run a full backup and assigned 3 slots(tapes) to that job. The first 4 days the differentail job ran and appended to the correct tape. Once the tape was full it did not locate the next tape assigned to the job. I received a message "No appendable media could be mounted" and the job failed. The tape was not flaged as FULL, so I do not understand what happened. I noticed before I set-up this process that tapes I set-up went into the Scratch Media section and the jobs would grab them as needed. Now that I set uup 2 jobs, I assigned job names to the tapes and moved them to the job media instead of scratch media section. Am I wrong in doing this????
