Looking for a free byte level file replicator/sync application

[tgabe213]

What experience do you have with what software that does byte level sync'ing?

I'll be working with 20-60GB VHD files that I'm going to be running on an e-sata hard drive (to get my VM's off the host drive). However, there may be times that I need to undock, and take my laptop in to a meeting (often last minute too). This is why I'd like to find something that does byte level syncing so it can be quick.

Thanks!

Note: I'm running Windows Server 2008 R2 Enterprise.

Does Server 2008 R2 DFS (Distributed File System) support sync'ing to an external hard drive? DFS seems like it may be a bit heavy for what I need.

Try Delta Copy. It is basically rsync for Windows with a few additions and should meet your needs.
