I need to synchronize often two large directories (with lots of sub directories and files) between a Windows XP and a Unix Server. (I currently do it with the nice WinSCP, but have tried a bunch of others.)
My problem is that every time I synchronize, the software checks every file to see if it has been updated. That takes about 1 minute.
I dream of a software that would keep track on both systems of which directory was updated, and wouldn't visit a directory unless needed.
Since I usually change just a few files, that should speed up my sync time from 1 minute to at most 1 sec.
Is there any software that does that, free or not?
One solution would be to synchronize both systems to some remote thing like DropBox. There is a number of reasons why I do not want to do that. It slows everything, it costs, and also I do not need my files in any other place.
Thanks.
