mimimal backup of working copies?

[Les Mikesell]

Does anyone know of a way to backup/move/copy checked out working copies 
such that you can skip all the parts that 'svn update' would 
reconstruct?  I'm about to copy the home directories of a machine used 
mostly for checkout/build/test operations to a remote location and it 
occurred to me that most of what I'll be copying is unnecessary but I 
don't want to disrupt the directory structure or hooks to the repositories.
