dump/restore is an exact file by file copy of a filesystem, it
replicates the directory entries quite exactly including all supported
attributes.. I probably got in the habit of using it from Solaris,
which has the rather similar ufsdump/ufsrestore.
another method is
cd /source; tar clf - . | (cd /dest; tar xvf -)
but not all versions of tar have the -l (--one-file-system) option (gnu
tar in CentOS does, however).
oh yeah, dump will dump an unmounted filesytem too, so in fact, that
could have been...
mount /dev/hda1 /mnt/dst
dump 0f - /dev/hdb1 | restore rf -
