Mapped Drive

[Stephen Zemlicka]

I think I got it (with the help of a friend).  You can, in fact, rsync to a
mapped drive efficiently.  You must include --no-whole-file.  My 100MB file
only transferred a few MB using that method and it opened up with the
changes just fine.  Now it works just like I want.  It's not the quickest
but definitely quicker than uploading hundreds of MB for each database.
Thanks you for the assistance.

If the only access you have to the remote directory is to read or
write it via a mapped drive, you can't hope to do any better than
copying the whole file.  All approaches to delta transfers rely on
performing some kind of special computation on the remote machine.

BTW, are you pushing files to the mapped drive or pulling files from
it?  Knowing that would make future discussion clearer.

rdiff is essentially a command-line interface to the three stages of
the rsync delta-transfer algorithm.  It won't work any better than
rsync in this setting.
