DFS-R Staging on WinSvr 2012

I have 2 questions about DFS-R staging.

#1 When using my backup software to perform the restore, do I have to restore the folder or the files or either...?

#2 Since a target folder is across the Internet and is 45 GB, can I restore the files to a USD Hard drive and the copy the files to the target DFS-R folder for staging...?

Thanks,

Tom...
