It depends on what your're doing.
the vos dump writes a volume like on stream. It doesn't really care 
about where a specific file is stored. If you have to deal with filters 
by filename or things like that you have to worry about the information 
in the dump including ACLs etc. That's pretty slow because you have to 
parse and seek the dump file.
