All -of the source code is available under a choice of two Free Software, -Open Source licences. +https://tahoe-lafs.org/source/tahoe-lafs/trunk/docs/quickstart.rst -This filesystem is encrypted and distributed over multiple peers in -such a way it continues to function even when some of the peers are -unavailable, malfunctioning, or malicious. +Tahoe-LAFS is the first distributed storage system to offer +"provider-independent security" — meaning that not even the +operators of your storage servers can read or alter your data +without your consent. Here is the one-page explanation of its +unique security and fault-tolerance properties: -Here is the one-page explanation of the security and fault-tolerance -properties that it offers: +https://tahoe-lafs.org/source/tahoe-lafs/trunk/docs/about.rst -http://allmydata.org/source/tahoe/trunk/docs/about.html +The previous stable release of Tahoe-LAFS was v1.10.1, released +on June 15, 2015. -This is the successor to v1.2, which was released July 21, 2008 [1]. -This is a major new release, adding a repairer, an efficient backup -command, support for large files, an (S)FTP server, and much more. +v1.10.2 is a small bugfix release, which fixes a critical +packaging error that prevented v1.10.1 from building against the +latest version of the upstream "mock" library. A few small bugs +were fixed too. See the NEWS file [1] for details. -See the NEWS file [2] and the known_issues.txt file [3] for more -information. -In addition to the many new features of Tahoe itself, a handful of -related projects have sprung up, including Tahoe frontends for Windows -and Macintosh, two front-ends written in JavaScript, a Tahoe plugin for -duplicity, a Tahoe plugin for TiddlyWiki, a project to create a new -backup tool, CIFS/SMB integration, an iPhone app, and three incomplete -Tahoe frontends for FUSE. See Related Projects on the wiki: [4]. - - -COMPATIBILITY - -The version 1 branch of Tahoe is the basis of the consumer backup -product from Allmydata, Inc. -- http://allmydata.com . - -Tahoe v1.3 is fully compatible with the version 1 branch of Tahoe. -Files written by v1.3 clients can be read by clients of all versions -back to v1.0 (unless the file is too large -- with the default -configuration, files greater than 12 GiB can't be read by older -clients). v1.3 clients can read files produced by clients of all -versions since v1.0. v1.3 servers can serve clients of all versions -back to v1.0 and v1.3 clients can use servers of all versions back to -v1.0 (but can't upload large files to them). +WHAT IS IT GOOD FOR? -This is the fourth release in the version 1 series. We believe that -this version of Tahoe is stable enough to rely on as a permanent store -of valuable data. The version 1 branch of Tahoe will be actively -supported and maintained for the forseeable future, and future versions -of Tahoe will retain the ability to read files and directories produced -by Tahoe v1 for the forseeable future. +With Tahoe-LAFS, you distribute your data across multiple +servers. Even if some of the servers fail or are taken over +by an attacker, the entire file store continues to function +correctly, preserving your privacy and security. You can +easily share specific files and directories with other people. +In addition to the core storage system itself, volunteers +have built other projects on top of Tahoe-LAFS and have +integrated Tahoe-LAFS with existing systems, including +Windows, JavaScript, iPhone, Android, Hadoop, Flume, Django, +Puppet, bzr, mercurial, perforce, duplicity, TiddlyWiki, and +more. See the Related Projects page on the wiki [3]. -WHAT IS IT GOOD FOR? +We believe that strong cryptography, Free and Open Source +Software, erasure coding, and principled engineering practices +make Tahoe-LAFS safer than RAID, removable drive, tape, +on-line backup or cloud storage. -With Tahoe, you can distribute your filesystem across a set of -computers, such that if some of the computers fail or turn out to be -malicious, the entire filesystem continues to be available, thanks to -the remaining computers. You can also share your files with other -users, using a simple and flexible access control scheme. +This software is developed under test-driven development, and +there are no known bugs or security flaws which would +compromise confidentiality or data integrity under recommended +use. (For all important issues that we are currently aware of +please see the known_issues.rst file [2].) -Because this software is the product of less than three years of active -development, we do not categorically recommend it as the sole -repository of data which is extremely confidential or precious. -However, we believe that erasure coding, strong encryption, Free/Open -Source Software and careful engineering make Tahoe safer than common -alternatives, such as RAID, removable drive, tape, or "on-line storage" -or "Cloud storage" systems. -This software comes with extensive unit tests [5], and there are no -known security flaws which would compromise confidentiality or data -integrity. (For all currently known issues please see the -known_issues.txt file [2].) +COMPATIBILITY -This release of Tahoe is suitable for the "friendnet" use case [6] -- -it is easy to create a filesystem spread over the computers of you and -your friends so that you can share disk space and files. +This release should be compatible with the version 1 series of +Tahoe-LAFS. Clients from this release can write files and +directories in the format used by clients of all versions back +to v1.0 (which was released March 25, 2008). Clients from this +release can read files and directories produced by clients of +all versions since v1.0. Servers from this release can serve +clients of all versions back to v1.0 and clients from this +release can use servers of all versions back to v1.0. + +Except for the new optional MDMF format, we have not made any +intentional compatibility changes. However we do not yet have +the test infrastructure to continuously verify that all new +versions are interoperable with previous versions. We intend +to build such an infrastructure in the future. + +The new Introducer protocol added in v1.10 is backwards +compatible with older clients and introducer servers, however +some features will be unavailable when an older node is +involved. Please see docs/nodekeys.rst [14] for details. + +This is the nineteenth release in the version 1 series. This +series of Tahoe-LAFS will be actively supported and maintained +for the foreseeable future, and future versions of Tahoe-LAFS +will retain the ability to read and write files compatible +with this series.
