XCopy is a very useful tool included in all versions of Windows. With XCopy you can copy large amounts of data with ease. Plus it has a switch that lets you copy over the NTFS permissions.
Creating an initial full copy with XCopy
xcopy "C:\Source Folder" "F:\Destination Folder" /X /H /E /V /C
Copy files and folders that changed since initial copy
xcopy "C:\Source Folder" "F:\Destination Folder" /X /H /E /V /D /Y /C
Explanation of XCopy switches
/? – Shows a list of all possible XCopy commands.
/X – Copies file audit settings and file ownership and ACL information.
