Doing it safely will require something like lvm or evms snapshots.  You
could do the sector by sector copy and then run reiserfsck
--rebuild-tree.  The latest versions of reiserfsprogs are faster, the
speed relative to a search for updated files will depend on your data
set.

More importantly you just don't get a consistent copy, regardless of the
FS you choose.  I wouldn't consider a sector by sector copy on a mounted
FS a valid backup of any type of filesystem, especially not a tree based
one.
