@ -5,25 +5,36 @@ lzip compressed data format (.lz), able to repair slightly damaged
files, recover badly damaged files from two or more copies, extract data
from damaged files, decompress files and test integrity of files.
The lzip file format is designed for long-term data archiving. It is
clean, provides very safe 4 factor integrity checking, and is backed by
the recovery capabilities of lziprecover.
The lzip file format is designed for long-term data archiving, taking
into account both data integrity and decoder availability:
* The lzip format provides very safe integrity checking and some data
recovery means. The lziprecover program can repair bit-flip errors
(one of the most common forms of data corruption) in lzip files,
and provides data recovery capabilities, including error-checked
merging of damaged copies of a file.
* The lzip format is as simple as possible (but not simpler). The
lzip manual provides the code of a simple decompressor along with a
detailed explanation of how it works, so that with the only help of
the lzip manual it would be possible for a digital archaeologist to
extract the data from a lzip file long after quantum computers
eventually render LZMA obsolete.
* Additionally lzip is copylefted, which guarantees that it will
remain free forever.
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.
Lziprecover makes lzip files resistant to bit-flip (one of the most
common forms of data corruption), and can safely merge multiple damaged
backup copies.
If the cause of file corruption is damaged media, the combination
GNU ddrescue + lziprecover is the best option for recovering data from
multiple damaged copies.
If a file is too damaged for lziprecover to repair it, all the
recoverable data in all members of the file can be extracted with the
'-D' option.
recoverable data in all members of the file can be extracted in one step
with the '-D' option.
Lziprecover is able to efficiently extract a range of bytes from a
multi-member file, because it only decompresses the members containing
