Recursively backup local computer directories to external drive

Recursively (incremental)  backup local computer directories CAS and real-server to external drive (j)
I used Deltacopy\rsync.exe (download from Internet) to backup files in Windows 7 to external disk J.
type cmd in Windows search box in Start, under Windows prompt
