It is normal in that when someone says "RTFM", they really want you to read
the manual entry.

I've enclosed an extract from the man page entry for ft for you to read ---
you really should read it as the two examples there show how to save data
to tape and how to retrieve data from tape.  In each case, the ft command
is being used as a "conduit" between a tar command and the actual tape
drive i.e. a pipe.  The NOTES are probably important too.

Try a little experimenting by saving a few files and then retrieving them.
If it works, maybe thank the guy who first suggested its use.

Extract from "man ft":


FT(8)			FreeBSD System Manager's Manual 		 FT(8)

NAME
     ft - QIC 40/80 floppy tape drive controller

SYNOPSIS
     ft [-f tape] [description]

DESCRIPTION
     The ft command allows multi-volume dump, extract, and view of tape la-
     bels, for any pre-formatted QIC-40/80 tapes.  It is totally system depen-
     dent, and has nothing to do with the QIC standards.

     ft is used primarily as a filter for tape i/o.  For example, to save and
     compress the /usr directory to tape:

	   % tar cvzf - /usr | ft "/usr save"

     To extract /usr from tape:

	   % ft | tar xvzf -

BUGS
     Formatting/Verifying is in the works.  You will need to use your existing
     backup program to do this for the time being.

NOTES
     The floppy tape driver supports tape drives such as ...
