Why not use cp or mv to move /usr/home to /storage/export/home? Weird things happen to hard and softlinks when you mv or cp. Try it and remember that a mv between different filesystems is actually a copy and delete.

Try this instead:
# tar -C /usr -cf - home | tar -C /storage/export -xvf -

Or, to copy to a remote machine:
# tar -C /usr -cf - home | ssh user@somemachine tar -C /storage/export -xvf -

You may want to add the -z switch to the tar commands. It will add compression but it depends on the type of data and your connection speed if it really improves transfer speeds.

1. Why bother to use the -f flag when you are sending to stdout anyway... (example pulling files from a remote server)
  <pre>ssh user@sourceserver tar -C /media -cz share | tar -xvz</pre>
2. Do not forget the -S option to handle sparse files efficiently when needed (like transfering a virtual machine disk).
