The dump utility backs up by file system, not by drive.
You told it to back up the '/' file system and it apparently did.
(That was that final '/' in your command line. I don't think
the first '/' belongs there unless it is something odd that I
have been missing - so I think the command should read:
dump -0aLf /usr/home/H/bsd_bkp/1116 /
that is if '/usr/home/H/bsd_bkp/1116' is really the correct
place to write the dump file)_
You then may also want to run dump for /usr and /var. That would
get the rest of the drive that is meaningful.
You probably don't want to bother with /tmp though you could.
