.SH NAME
tarlz \- creates tar archives with multimember lzip compression
.SH SYNOPSIS
.B tarlz
[\fI\,options\/\fR] [\fI\,files\/\fR]
.SH DESCRIPTION
Tarlz is a combined implementation of the tar archiver and the lzip
compressor. By default tarlz creates, lists and extracts archives in a
simplified posix pax format compressed with lzip on a per file basis. Each
tar member is compressed in its own lzip member, as well as the end\-of\-file
blocks. This method adds an indexed lzip layer on top of the tar archive,
making it possible to decode the archive safely in parallel. The resulting
multimember tar.lz archive is fully backward compatible with standard tar
tools like GNU tar, which treat it like any other tar.lz archive. Tarlz can
append files to the end of such compressed archives.
.PP
The tarlz file format is a safe posix\-style backup format. In case of
corruption, tarlz can extract all the undamaged members from the tar.lz
archive, skipping over the damaged members, just like the standard
(uncompressed) tar. Moreover, the option '\-\-keep\-damaged' can be used to
recover as much data as possible from each damaged member, and lziprecover
can be used to recover some of the damaged members.
