[CLUE-Tech] using DUMP

[Dan Harris]

Hey all, my usual backup software (Tapeware) is not working correctly and I need to do a "dump" without it tonight.  I can dump one volume to the tape correctly, but I need to dump /usr and /usr2 onto a tape;

I'm doing this:

/sbin/dump 0bf 64 /dev/st0 /usr


The problem is that if I do it again with /usr2 it overwrites the existing tape.  How can I append /usr2? 

Thanks
