Restoring file shares and permissions

I have two servers running WIndows 2000. I need to back up the data on one, and temporarily put it on the other, while the first one gets a complete rebuild. To save me some time and effort, I’d like to know if there is a utility or program that will allow me to back up all file shares and permissions on files and folders, so I don’t have to go and reset them all after the rebuild. Any suggestions?

Thanks in advance, David.
