parchive - Online in the Cloud

PROGRAM:

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 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.
