AMDD(8)                      System Manager's Manual                     AMDD(8)



NAME
       amdd - Amanda version of dd

SYNOPSIS
       amdd [ -d ] [ if=input ] [ of=output ] [ bs=blocksize ] [ skip=count ] [
       count=count ]

DESCRIPTION
       Amdd provides just enough of the standard dd command for the needs of
       Amanda.  This is handy when doing a full restore and the standard dd
       program has not yet been found.

       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.

       See the amanda(8) man page for more details about Amanda.  See the OUTPUT
       DRIVERS section of amanda(8) for more information on the Amanda output
       drivers.

OPTIONS
       -d     Turn on debugging output.

       -llength
              Set the output length.  If the output driver limits the output
              size, this controls when end of tape will be simulated.

              Length may have a multiplier suffix:

                     k 1024 (Kilobytes)

                     b 512 (Blocks)

                     M 1024*1024 (Megabytes)

              The default is no multipler (bytes).

       if=input
              Input to dd.  Default is stdin.

       of=output
              Where to send the output of dd.  Default is stdout.

       bs=blocksize
              Size of each record.  Input records smaller than this will not be
              padded.  Output records will be the same size as the corresponding
              input record.  Default is 512 bytes.

              Blocksize may have a multiplier suffix:

                     k 1024 (Kilobytes)

                     b 512 (Blocks)

                     M 1024*1024 (Megabytes)

              The default is no multipler (bytes).

       count=count
              Number of records to copy.  Default is all records until end of
              file.

       skip=count
              Number of records to skip before copying input to output.  Default
              is zero.
