Command:   vol - split stdin into diskette-sized volumes
Syntax:    vol [-rw] [size] block_special
Flags:     -u  Unsave from diskettes
Examples:  tar cf - . | vol -w 360 /dev/fd0 # Prompt for disk every 360K
           vol -r 360 /dev/fd0 | tar xf - # Restore a saved file system

     It occasionally happens that a program generates an  output  stream
intended for diskette but the stream is to large to fit on one diskette.
Vol is a program that accepts such  a  stream,  and  pauses  every  size
blocks  to request a new diskette to be inserted. This makes it possible
to save arbitrarily long streams on a series of diskettes, as  shown  in
the examples above.

     You do not have to use the -r or -w options if you use vol  on  the
command  line,  it  will  figure out by itself what the direction of the
data is.  The size of the device also need not be specified if you  know
that  the  device  is large enough, like a tape.  Vol is then useful for
the buffering it does, because tar doesn't buffer.
