Dump Help

As you all  can tell by now I'm new to this, and I'm avidly reading through
my AbsoluteBsd book.

I don't really save any data to the BSD box just logs, I use it for scanning
email  (Exim, ClamAV, SA) 

My  goal is to backup the file/files/partitions  so that if the box blew up ,
I can just grab a new box install bsd , then restore  it.

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.
