Using TIE 9.1.3534 I want to pull full "images" (not diff or inc) to 4MM tape on a weekly basis, do it on an unattended basis and rotate through 5 tapes. When I run the first backup per tape it works just fine. When I try to overwrite the 1st tape, I get a message that say you must clean the tape first. Click "OK" and it proceeds along just fine. I have already selected the "overwrite tape option" and that makes no difference. I have tried erasing the tape using the mtfcheck.exe utility in W2k server resource kit to no avail. Is there a command line option with ATIE that will allow me to schedule a task that will "clean" the tape prior to running the image backup?? What is the work around for this?
