Having to erase tapes every backup

[imak]

Hi, we are having to erase tapes for every backup
We have bought new dds4 tapes and using veritas backup exec 10. Just as the job starts, it comes up with a write protection error and asks us to erase the tape?
When we have erased the tape, the backup runs fine!
Does anyone have a solution for this?
Thanks,
Ian

I use a Grandfather, Father, Son backup scheme, and I erase my tapes before each backup. I ran into the same problem and I fixed it by expanding my tape library.

What is your overwrite protection period set to?

In your backup job, do you have "Append, Overwrite if no Appendable media is available" set?

Hi, thanks for your reply airbourne.
We have overwrite media selected as we do a full backup :
mon to thurs and 6 fridays!
It;s the same setup as the other server's bakcupu jobs and they work fine, so i don't know?
Thanks,
Ian
