Lziprecover is a data recovery tool and decompressor for files in the lzip compressed data format (.lz), able to repair slightly damaged files, 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 is able to recover or decompress files produced by any of the compressors in the lzip family; lzip, plzip, minilzip/lzlib, clzip and pdlzip.

The lzip file format is designed for data sharing and long-term archiving, taking into account both data integrity and decoder availability.

A nice feature of the lzip format is that a corrupt byte is easier to repair the nearer it is from the beginning of the file. Therefore, with the help of lziprecover, losing an entire archive just because of a corrupt byte near the beginning is a thing of the past.

If the cause of file corruption is damaged media, the combination GNU ddrescue[1] + lziprecover is the best option for recovering data from multiple damaged copies.

The homepage is at http://www.nongnu.org/lzip/lziprecover.html

Changes in this version:

* "--repair" now tries to detect gross damage in the file before attempting to repair it.

* "--repair" now tries bytes at member offsets 7 and 8 first because errors in these bytes sometimes can't be detected until the end of the member.

* The new option "-x, --show-packets", which shows the LZMA packets (coding sequences) coded in a given file, has been added.
