HELP - backup to /dev/null on NT ???

Hi, I was having problems with my server on an NT 4.0 workstation and some of you suggested that my logs might have filled up. I should have checked that. So the logs were in fact full. I now need to dump the logical logs and do not want to write them to an actual tape. I have the LTAPEDEV in my onconfig file set to "NUL". When I do an ontape -a, I get "Please mount tape 1 on "NUL" and press Return to continue ..." When I hit a return on this, I get "Logbackup failed - function open tape device "NUL" failed code -1 errno 2 Without performing the backup, I am stuck. Is there no equivalent to /dev/null of UNIX on NT? Any help appreciated. Thanks. -Hari ---
