where's 'dump'?

Here is my solution.  I don't have a tape drive, so I ftp the files
to a HP9000 and use fbackup there to get everything.  be aware that
doing an NFS export to another system for backups is SLOW and on
the HP9000 used for this purpose, NFS caused holes in the backup.

Hope this helps someone.
