I think you can get dump/rdump from the UUNET 4.3bsd source tree.

Note that the design of dump makes it very difficult to extend to
NFS-mounted directories, so you should plan on extending rdump to support
the 3480 drive (this probably just involves recognizing the device-specific
status flags).  It accesses the partition through the raw disk device, not
through the file system system calls, but the NFS protocol only supports
file system operations.  If you want to be able to dump NFS-mounted file
systems you can use utilities such as tar (GNU tar includes some options
that are intended to support its use within a backup system) or other
3rd-party backup utilities.
