One copy tool that's not well known is RichCopy from Microsoft. It's a great copy util when dealing with huge amount of files. It supports parallel copy, resume from failed, and copy only changed files.

RichCopy is always one of the first tools I install on any of my machines. It's an amazingly powerful tool. About the only thing missing with RichCopy is integration with Explorer Shell.

Oh interesting! I'll have to take a look. Right now I use TeraCopy.

So Windows users finally don't have to install cygwin for rsync

I suppose. If you didn't know about Robocopy (http://en.wikipedia.org/wiki/Robocopy) which has been around since the NT days.

Rsync under Cygwin was always too slow. Any sort of significant I/O is slow under Cygwin.

Robocopy, while useful, does not have very many of the features of rsync, apart from retries.

True, Rsync has more features, but Robocopy is still a very useful tool. And it has been included in Windows since Vista.

But with all the problems of rsync and cygwin on Windows, Robocopy is the more logical choice for such tasks. I'm not going to load up explorer.exe in WINE on Linux so I can move some files around with the mouse.

Rsync in cygwin also (severely) messes up your files' and folders' NTFS-permissions when synching against a linux-host, which can lead to things like the meltdown of a complete IIS website/webserver setup since the IIS worker process can no longer access the files it needs.

I've learnt the hard way that you dont use rsync in cygwin for anything remotely crucial ;)
