This is an open and neutral LTFS (Linear Tape File System) implementation, without the proprietary extensions from the different vendors. It implements the version 2.4.0 of the format specification, while the ISO/IEC 20919:2016 standard, which is still officially the valid one, considers the version 2.2.0. The proof of concept is done with the openLTO package.

The openLTFS package contains the libltfs C library, which provides the classic ltfs and mkltfs commands, and the openltfs Bash command-line interface. The package is released under a Creative Commons Attribution 4.0 International License and is provided «as is» without warranty or support of any kind.

A PDF of the current man page is available.

The source code will become freely available, as soon as a public beta will be released.

Our clients can already install and test an alpha by running the following command:

brew install avpres/formulae/openltfs
