Mixed Distribution Point Sync

I haven't used it specifically for DP replication, but have a look at Robocopy. ("Robust Copy") It's a tool from Microsoft. http://technet.microsoft.com/en-us/library/cc733145%28WS.10%29.aspx

There's *loads* of options for copying your files. It's powerful and it may take some experimenting but it'll likely do you quite well.

Robocopy is a potential answer. I have been looking at a few tools including several that use rsync as a backend. I am hoping to find something that will do a diff copy similar to rsync as the distro in question will offshore and reducing bandwidth will be an issue.

Robocopy will do this. It primarily looks at file creation/modification dates and file sizes as the properties to determine changed files.

batch files with powershell. Powershell is Microsoft's answer to every Unix admin out there that wants commands to script and automate. I personally have only slightly dabbled in it. However, with Windows Task Manager (or whatever it is Windows uses for scheduling tasks these days) and a simple script you can automate all sorts of things. Copying data across servers at midnight every night for example would be an easy task. No need to buy third party, or deal with third party when you can roll your own.

Let me take a peak at powershell and see whats up.

Edit -

OK, found this sample script via Google and as you can see it is VERY Unix-like
