.SH NAME
lziprecover \- recovers data from damaged lzip files
.SH SYNOPSIS
.B lziprecover
[\fI\,options\/\fR] [\fI\,files\/\fR]
.SH DESCRIPTION
Lziprecover \- Data recovery tool and decompressor for the lzip format.
Lziprecover is a data recovery tool and decompressor for files in the lzip
compressed data format (.lz). Lziprecover is 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.
.PP
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.
.PP
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 can remove the damaged members from multimember files, for
example multimember tar.lz archives.
.PP
Lziprecover provides random access to the data in multimember files; it
only decompresses the members containing the desired data.

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

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