Should be no problem because dump/restore work on a file-by-file basis
and not blocks or other hardware divisions.   Since it will have to
build directories and such, it might come out just a bit bigger than
the actual dump file, but it should only use in the ballpark of the
size of the dump file.   

Anyway, it does not depend on the size of the file system that was 
dumped, but rather on the amount of data that was dumped.
