Okay, that's a brief description but is clearer than we had before.

Forget about gzip for now; just concentrate on the *problem* to be
solved, and don't assume a particular technique. There are other ways of
addressing limited bandwidth.

Again, don't assume a particular technique until it's demonstrated that
it's better than alternatives; default to a simple implementation first.

Nothing in your description speaks to a need for a daemon. What it
sounds like you need is two programs, one running at each end of a
network connection. Whether they are daemons or not is irrelevant.

That's the core of the problem to be solved, in my view. For now, forget
about limited network bandwidth or how these processes will run.

Are you able to get your particular data out of the one system and into
the other, successfully? What have you tried so far to do this, and what
exactly went wrong?

What was the result of this on your specific data set? If you have
issues related to Oracle or MS servers, or their implementations of SQL,
you'll need to seek assistance in forums specific to those products.
