.SH DESCRIPTION
.B Amdd
provides just enough of the standard
.UX
.B dd
command for the needs of Amanda.
This is handy when doing a full restore and the standard
.B dd
program has not yet been found.
.LP
.B Amdd
also provides access to the Amanda output drivers that support
various tape simulations.
This may be used for debugging or to convert from one format
to another.
.LP
See the
.IR amanda (8)
man page for more details about Amanda.
See the
.B OUTPUT DRIVERS

.BR dd .
Default is stdin.
.TP
.B of=\fIoutput
