NAME

       parchive - RAID like data recovery for PAR ver 1.0 files

DESCRIPTION

       The  idea  behind  the parchive is to provide a tool to apply the data-recovery capability
       concepts of RAID-like systems to the  posting  and  recovery  of  multi-part  archives  on
       Usenet.  Current  filespec and clients support the 'Reed-Soloman Code' implementation that
       allows for recovery of any 'X' volumes for 'X' parity volumes present.

       The key to this mission is a clean  file  format  specification  which  provides  all  the
       necessary  capabilities  for programs to easily verify and regenerate single missing parts
       out of a set of archives.

       We might just be able to make binary posting and downloading on Usenet  a  little  easier.
       That's a pretty cool goal!

       Note  that parchive supports the old legacy version 1.0 PAR format.  For new projects, use
       the par2 package which supports  the  version  2.0  PAR  format  which  provides  superior
       features.

       This  manual  page  was written for the Debian GNU/Linux distribution because the original
       program does not have a manual page.

              Check parity archive

       parchive r(ecover) [options] <par file>
              Restore missing volumes

       parchive a(dd) [options] <par file> [files]
              Add files to parity archive

       parchive m(ix) [options]

       -m     Move existing files out of the way

       -f     Fix faulty filenames

       -p<n>  Number of files per parity volume

       -n<n>  Number of parity volumes to create

       -d     Search for duplicate files
