XXCOPY Backups to CDR, with Restore

Hi Kan ... in this yahoo group I have seen several people mention that
shareware utilities such as doslfnbk apparently DO make it possible to
preserve the SFN when using xxcopy to clone-copy between a hard drive and a
CD. I myself have no connection to doslfnbk, but I wonder why you never
seem to mention doslfnbk when this limitation of xxcopy becomes a
consideration?? Why suggest to the users that their only option it to
choose /NX0 and accept that there is a risk (a risk which, in many cases
involving the operating system and installed programs, can be a certainty)
that their backups will fail when the time comes to restore? Why not
mention doslfnbk, or something comparable? (with Ghost etc as the only
other reliable alternative)

As a second question, you'd mentioned that some consideration has been given
to resolve this limitation in xxcopy (since the capability to backup to CDRs
or CDRWs is very useful). Any specific plans? (I'm putting aside for now
the consideration that when xxcopy was first developed its ability to
restore operating systems and installed programs was not part of the
anticipated benefits, but a fortunate result of building a solid product.)
