Are all the jobs overwrite, or are they append?

Do they all use the same media set?

What is the OPP (Overwrite Protection period) for the media set(s)?

where would i see those? i didnt set up the backup jobs, just monitor them now. thanks

Job Log, Right Click\Properties to see the job definitions

Media tab, right click the media set \Properties to see the OPP and APP for each media set

Daily: OPP - 13 days : APP - Infinite - Allow Append

Weekly: OPP -3 weeks : APP - Infinite - Allow Append

Very strange.  With those settings, the Weeklky should be safe for three weeks

Does the jog log for the weekly show a successful completion? 

Yeah, it all shows successful completions, and when i view the media details for the job that ran, it says the same tape. This has happened before when the company had a day off, backup still ran that night, but that tape used said it was the same as the previous nights. im not sure what to make of this.

it won't unscrew things as they exist, but I'd recommend a database repair using BEUTIL

ok, id have to recommend it to the person who actually edits the backup exec. what could be the problem? do you think its actually using seperate tapes but it just reports that it uses the same?

do you think its actually using seperate tapes but it just reports that it uses the same

I doubt that. 

The only other thing can think of would be to verify that the job is writing to the media set that you think it is, not to another media set with different properties (I know, that is reaching, but as I said, it's all I can think of)

ok, i appreciate your help on this
