That is fine for backup...

...but that clobbers the partition table, which lives in the bytes
following the 446-byte MBR in the first sector.  This may not matter
to you, but if it does, you can use my little Perl script (on Unix):

  http://cvs.sourceforge.net/viewcvs.py/unattended/unattended/linuxboot/tools/install-mbr.pl?rev=HEAD&view=auto

Run it with no arguments for a usage summary.
