.SH DESCRIPTION
Tarlz is a massively parallel (multi\-threaded) combined implementation of
the tar archiver and the lzip compressor. Tarlz creates, lists and extracts
archives in a simplified posix pax format compressed with lzip, keeping the
alignment between tar members and lzip members. 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.

Keeping the alignment between tar members and lzip members has two
advantages. It adds an indexed lzip layer on top of the tar archive, making
it possible to decode the archive safely in parallel. It also minimizes the
amount of data lost in case of corruption.
.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
