Hi All,

if you are appending then Backup Exec will use the remaining space and then use a second tape if that available space is not enough for the job, as such apart from when all the jobs overwrite the tape it is very possible that you might use more tapes than expected.
Note You cannot append to the end of a tape and when that tape fills start using the beginning of the same tape, a seconnd tape will be used - and that second tape has to be overwritten as well the second tape cannot be appended to.

I get that part but each day im pulling 15 tapes out and 7 of them have less than 50gb written to them. They can support up to 1.5TB compressed.
Its as if the job finishes, the tape is sent back to its slot, the next job starts and commences on a new media in the library rather than appending to the tape that just finished job 1....

My answer in this post was kind of an assumption that you daily backup was trying to use two tapes when you expected it to use 1.
Having now seen your other post, please see my answer in the other post for scenarios where a small amounts of data is written to a tape but the tape is not filled and instead other tapes are used.
Basically between the two posts you need to look at
Which jobs start as overwrites
Which jobs start as append
Which media sets each jobs use
How many jobs run in parallel
