I think he was talking about a full filesystem restore in which 
case 'restore -rf' would be correct.

The man page actually is a tiny bit misleading on the -r.
You can use it to restore the whole filesystem in any dedicated space
including any directory.   But with -r you just cannot specify which part 
of the filesystem you want to restore, such as a particular directory 
or file.  For that you will need -xf which will work for a full filesystem 
too in most cases.
