ufsdump is preferable to tar on older Solaris systems, as Solaris tar (of
that vintage) is rather limited in its ability to handle long (> 100
character) filenames, and GNU tar doesn't always do the right thing with
"door" files on Solaris.

If I were in your situation, I'd make a dd image, a ufsdump image of each
slice, and a NFS-mountable mirror of the disk using ufsdump | (cd dest && 
ufsrestore r).

The dd-image gets you something you can use if everything blows up.  The
ufsdump images give you convenient ways to restore individual files, and
the NFS-mountable mirror gives you a way to do "offline" experimentation,
to the degree that it makes sense.  If you can netboot the notebook, it'll
be even more useful.
