I am using Backup Exec 12 and an HP 1/8 G2 Autoloader.

The backups are using same two tapes instead of rotating through seven tapes.

I have included a screenshot of both backup exec screen showing the slots and a shot of the Autoloader config page which shows "automatic" for tape selection.

Do you have media sets setup? You should puit all 7 in the scratch media, then set a overwrite or amend period and once a backup is run, it will p[ut the tape in the media set and then next backup will use another tape from the media set until they are all used or the period of the media set has expired. Does that help>?

So if I put all seven slots/tapes in scratch media, the daily backup is automatically going to pull a tape out of scratch and put in in a media set? Why don't I just put the 7 tapes in the appropriate media set in the beginning?

I have a media set setup, attached is the image of it with it's append/overwrite rules. Is it correct?

YEs that's right. If you put all your media in the scratch, then once the backup is done, it will put the tape in the media set you've specified. I would allow infinite append as you have and also put a 7 day overwrite protection if you are having one tape per day for example. The backup will finish put the tape in the media set. The next day will grab another tape from scratch, do it's stuff and then put that into th media set and so on....
Then after 7 days it will look for a tape it can either append to, or one it can overwrite, but the data will be proitected for 7 days reagrdless.
If you put your tapes straight into the media set to begin with, it will instantly take on the 7 days protection, so you can't use any of those tapes for 7 days. That had me stumped for a while!!!
If you want to use specific tapes for specific days, you will need to look at partitioning on the Backup exec help files.
Hope that helps
