The dump is just a file and it should not matter where it is
stored, but you will have to use some network access type thing
such as an rsh or an NFS connection to read it.

Another thing is that restores need to be done on the same OS
that the dumps were written - regardless of where they are stored.
dump/restore depends on knowing something about the underlying
filesystem, so it is not transferable from one system to another
and often even between one OS version to another, like tar tends
to be.    But, you can make the dump file move between where it is 
stored and a system that can restore from it using one of the 
network protocols.
