NAME
       lziprecover - recovers data from damaged lzip files

SYNOPSIS
       lziprecover [options] [files]

DESCRIPTION
       Lziprecover  is  a data recovery tool and decompressor for
       files in the lzip compressed data  format  (.lz).  Lzipre-
       cover  is able to repair slightly damaged files, produce a
       correct file by merging the good parts of two or more dam-
       aged  copies,  extract data from damaged files, decompress
       files and test integrity of files.

       Lziprecover can repair perfectly  most  files  with  small
       errors  (up  to one single-byte error per member), without
       the need of any extra redundance at all. Losing an  entire
       archive  just because of a corrupt byte near the beginning
       is a thing of the past.

       Lziprecover can remove the damaged members from  multimem-
       ber files, for example multimember tar.lz archives.

       Lziprecover  provides  random access to the data in multi-
       member files; it only decompresses the members  containing
       the desired data.

       Lziprecover  facilitates the management of metadata stored
       as trailing data in lzip files.

       Lziprecover is not a replacement for regular backups,  but
       a  last line of defense for the case where the backups are
       also damaged.
