I can't seem to get dump to do what I want.
What would be the proper dump command to dump a file system to a series of
files which are no larger than 650MB in size?

I tried the following command to see if dump would create a series of 10MB
files when dumping the /usr filesystem, but I keep getting prompted to
insert another volume once the 10MB limit is reached.

dump -0u -B10000 -f /usr/archive/test_dump_usr /usr

Any suggestions to automate this?
