NAME
       lziprecover - recovers data from damaged lzip files

SYNOPSIS
       lziprecover [options] [files]

DESCRIPTION
       Lziprecover  - Data recovery tool and decompressor for the
       lzip format.

       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 also produce a correct file by merging the
       good  parts  of  two  or more damaged copies, extract data
       from damaged files, decompress files and test integrity of
       files.

       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.
