I can’t seem to wrap my head around media management. I have a tape library with 4 drives. I’ve got the usual daily. Weekly, monthly jobs. When I add new media it gets sucked up pretty quick across the 4 drives, which I’m prepared to live with. However I have a big problem when it’s prompting me for over writeable media when I have tapes in the library with heaps of room on them. Some tapes have as little as a gig written to them and the job won’t run because it’s looking for media!
Now I was told by Symantec that if a job spans media it can’t append to media in the same media set if any data’s on that tape, and that it can only write to scratch tape. I just don’t’ understand that, but I’ve accepted it. However, subsequent jobs that just start, and would have not spanned any media are also prompting me for overwriteable media as well
My storage options are to append to media, overwrite if no appendable media is available and my BackupExec settings for media overwrite protection level is set to partial – protect only allocated media.
What’s going on??
