Yes, you can multithread the backups in a different way. Create another
nodename, a second dsm.opt file using that nodename, and include and
exclude lines like (assuming there are two NetWare volumes sys: and
vol1:

dsm.opt copy1 
nodename nwmachine-a
exclude *:/.../*
include sys:/.../*

dsm.opt copy2
nodename nwmachine-b
exclude *:/.../*
include vol1:/.../*

This can be done with three or more volumes as well. You can then easily
create two threads for your backups (and your restores) without the use
of resourceutilization, multiple mount points, etc.
