File System</b> (<b>LTFS</b>) is a <a href="/wiki/File_system" title="File system">file system</a> that allows files stored on <a href="/wiki/Magnetic_tape_data_storage" class="mw-redirect" title="Magnetic tape data storage">magnetic tape</a> to be accessed in a similar fashion to those on disk or removable flash drives. It requires both a specific format of data on the tape media and software to provide a file system interface to the data. </p><p>The technology, based around a self-describing tape format developed by <a href="/wiki/IBM" title="IBM">IBM</a>, was adopted by the <a href="/wiki/Linear_Tape-Open" title="Linear Tape-Open">LTO Consortium</a> in 2010. </p> <meta property="mw:PageProp/toc" /> <div class="mw-heading mw-heading2"><h2 id="History">History</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Linear_Tape_File_System&action=edit&section=1" title="Edit section: History"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p><a href="/wiki/Magnetic_tape_data_storage" class="mw-redirect" title="Magnetic tape data storage">Magnetic tape data storage</a> has been used for over 50 years, but typically did not hold file metadata in a form easy to access or modify independent of the file content data. Often external databases were used to maintain file metadata (file names, timestamps, directory hierarchy) to hold this data but these external databases were generally not designed for <a href="/wiki/Interoperability" title="Interoperability">interoperability</a> and tapes might or might not contain an index of their content. In <a href="/wiki/Unix-like" title="Unix-like">Unix-like</a> systems, there is the <a href="/wiki/Tar_(file_format)" class="mw-redirect" title="Tar (file format)">tar</a> interoperable standard, but this is not well-suited to allow modification of file metadata independent of modifying file content data - and does not maintain a central index of files nor provide a filesystem interface or characteristics. </p><p>LTFS technology was first implemented by IBM as a prototype running on Linux and Mac OS X during 2008/2009. This prototype was demonstrated at the <a href="/wiki/NAB_Show" title="NAB Show">NAB show</a> in 2009. Based on feedback from this initial demonstration and experience within IBM the filesystem was overhauled in preparation for release as a product. The LTFS development team worked with the vendors of LTO tape products (HP and Quantum) to build support and understanding of the LTFS format and filesystem implementation leading up to the public release. </p><p>The LTFS Format Specification and filesystem implementation were released on April 12, 2010 with the support of IBM, HP, Quantum, and the LTO Consortium.<sup id="cite_ref-1" class="reference"><a href="#cite_note-1"><span class="cite-bracket">[</span>1<span class="cite-bracket">]</span></a></sup> </p><p>LTFS v2.0.0 was released in March 2011, improving the text to clarify and remove ambiguity. It also added support for <a href="/wiki/Sparse_file" title="Sparse file">sparse files</a>; persistent file identifiers; virtual extended attributes for filesystem metadata and control - and defined minimum and recommended blocksize values for LTFS volumes, for compatibility across various HBA hardware implementations. </p><p>LTFS v2.2.0 was released in December 2013. It was the first version to become an ISO standard (20919:2016). </p><p>LTFS v2.5.1 was released in May 2019. It became the second version of the ISO standard (20919:2021).

Files are always appended to the end of the tape. If a file is modified and overwritten or removed from the volume, the associated tape blocks used are not freed up, they are simply marked as unavailable and the used volume capacity is not recovered. Data is only deleted and capacity recovered if the whole tape is reformatted.<sup class="noprint Inline-Template Template-Fact" style="white-space:nowrap;">[<i><a href="/wiki/Wikipedia:Citation_needed" title="Wikipedia:Citation needed"><span title="This claim needs references to reliable sources. (October 2015)">citation needed</span></a></i>]</sup> </p><p>In spite of these disadvantages, there are several uses cases where LTFS formatted tape is superior to disk and other data storage technologies. While LTO seek times can range from 10 to 100 seconds, the streaming data transfer rate can match or exceed spinning-disk data transfer rates. Additionally, LTO cartridges are easily transportable and hold far more data than any other removable data storage format. The ability to copy a large file or a large selection of files (up to 1.5TB uncompressed data for LTO-5, and 18TB for LTO-9) to an LTFS formatted tape, allows easy exchange of data to a collaborator, or the saving of an archival copy. </p><p>Since LTFS is an open standard, LTFS formatted tapes are usable by a wide variety of computing systems and operating systems, avoiding the incompatibilities caused by previous proprietary LTO filesystems.<sup id="cite_ref-9" class="reference"><a href="#cite_note-9"><span class="cite-bracket">[</span>9<span class="cite-bracket">]</span></a></sup> </p> <div class="mw-heading mw-heading2"><h2 id="Implementations">Implementations</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Linear_Tape_File_System&action=edit&section=5" title="Edit section: Implementations"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Tape drives manufacturers often offer two different editions, one for <i>Single Drives</i> and one for <i>Tape Libraries</i>, based on the <i>LTFS Reference Implementation</i>. </p> <div class="mw-heading mw-heading3"><h3 id="IBM_Linear_Tape_File_System_-_Single_Drive_Edition">IBM Linear Tape File System - Single Drive Edition</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Linear_Tape_File_System&action=edit&section=6" title="Edit section: IBM Linear Tape File System - Single Drive Edition"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>The <a href="/wiki/IBM" title="IBM">IBM</a> Linear Tape File System - Single Drive Edition, (initially released as "IBM Long Term File System"), allows tapes to be formatted as an LTFS volume, and for these volumes to be mounted - and users and applications access files and directories stored on the tape directly, including <a href="/wiki/Drag-and-drop" class="mw-redirect" title="Drag-and-drop">drag-and-drop</a> of files. </p> <div class="mw-heading mw-heading3"><h3 id="IBM_Linear_Tape_File_System_-_Library_Edition">IBM Linear Tape File System - Library Edition</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Linear_Tape_File_System&action=edit&section=7" title="Edit section: IBM Linear Tape File System - Library Edition"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>The <a href="/wiki/IBM" title="IBM">IBM</a> Linear Tape File System - Library Edition (LTFS-LE) product allows LTFS volumes to be used in a <a href="/wiki/Tape_library" title="Tape library">tape library</a>.
