Wouldn't it take a hour to send 3.5 MB at 9600 baud? On the surface it
would seem that your site didn't modify much in any one day. But then,
most of us may be supprised by how little is actually updated.
Back in the '70s there was an PNET/RJE function called RTPSEND and

In the early 1990's we consolidated a data center from Sydney into
Philadelphia. We used SYBACK to do a full dump of specific (most) minidisks
