FTP file CHANGES via Internet

[Guest]

I want to accomplish off-site data backup between two remote Windows 2003
servers via the Internet, each with a 3MB/768k DSL connection. (I couldn't
find a W2K3 discussion group.)

To make things manageable, I would like to find software that will only send
CHANGES to a file.

For example, my accounting file is 440MB in size. If I bring it to the
second computer on a CD and load it, the next day I would like to FTP the new
file by just sending the new information (<1MB) -- sending all 440MB would
just not work with a 768k upload speed.

In fact, I would love to create a script/job that copies deltas to all files
that have changed in a particular directory or drive to the other machine.
Thus, I would be able to mirror the data on both machines with relatively
little transmission.

Am I on drugs or dreaming?
1) Is there an FTP or equivalent protocol that does this? (I know, for
example, that PCAnywhere only sends the deltas in a screenshot, rather than
the whole screen, for refreshes. Seems to me that the same could be done for
files.)

2) Is there a product that has this technology that could also do the
directory/file management/synching?

Any advice you could give would be greatly appreciated!

SecondCopy from www.centered.com may do exactly what you want as far as
copying only the changed files to wherever you specify.

For server questions, try:
microsoft.public.windows.server.general or
microsoft.public.windows.server.sbs if you have Small Business Server
