How to copy very large directory trees

I have constant trouble with XCOPY/s for multi-gigabyte transfers.
I need a utility like XCOPY/S that remembers where it left off if I reboot. Is there such a utility? How about a free utility (free as in free beer)?

How about an md5sum sanity check too?

I posted the above query in another forum. Answers to the above question are welcome here too. My question for this forum is: How feasible is it it write a script in groovy, python, cygwin bash, Activestate perl, powershell, etc... to implement a linux "cp -R" or windows "xcopy/s" program that can continue where it left off after a reboot?

I cannot think of clever way do do this easily -- can you?

I could write it in C++ -- but I'm hoping for something more quick and elegant.

Thanks
Siegfried
