I'm trying to setup a file sync between the file server at my house and the one at my brother's so that we each have offsite backups of important data. Both systems are running Windows (XP on one, 7 on the other).
I like the fact that rsync will only transfer part of a file, the part that has changed, and not the whole thing...saving a lot of bandwidth. But I have had very little luck getting it to work properly. I tried using DeltaCopy, but it's interface is horrible, and while it will work within my LAN it always fails to connect when remote. (See this question for more details on that)
Is there another alternative program that runs on windows and has similar functionality? So far the only other option I can see is using FTP and something like SyncBackPro...but that is just going to transfer the whole file...and only having 512kbps upload bandwidth makes that a total pain.
Edit: To clarify some more, the backup I'm doing needs to scan several hundreds of thousands of files, adding up to more than 400GB, on each end... which is why I'm not using an intermediary service like LIVE for the transfer...
Edit 2: Also, these backups need to be preformed over a remote connection and without a VPN... Meaning that using Windows File Shares (SMB) is out of the question...
