From the manpage for restore:


     -f file
             Read the backup from file; file may be a special device file like
             /dev/rst0 (a tape drive), /dev/rsd1c (a disk drive), an ordinary
             file, or `-' (the standard input).  If the name of the file is of
             the form ``host:file'', or ``user@host:file'', restore reads from
             the named file on the remote host using rmt(8).  If the name of
             the file is `-', restore reads from standard input.  Thus,
             dump(8) and restore can be used in a pipeline to dump and restore
             a file system with the command

                   dump 0f - /usr | (cd /mnt; restore xf -)
