keepuptodate - transfer only the updated piece of a big file!

Hi guys!

I have a restaurant with a software that produce a file (the firebird database with product selled).

This file is 60mb and each time I sync that, I need 5 minutes. (too much for me)

It's possibile sync only the new part of the file...

if file before was 60mb and now is 60.01 mb... i push only the 0.01 part.

Thank a lot and compliment for your big ideas!

You can use -resume flag to transfer only the new tail of the file.

But that will work for a text files mostly only. So I'm not sure if that work for a FireBird database.
