All of the source code is available under -a Free Software, Open Source licence (or two). +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: -A one-page explanation of the security and fault-tolerance properties -that it offers is visible at: +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. +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. -This is the successor to Allmydata.org "Tahoe" Least Authority -Filesystem v1.1, which was released June 11, 2008 [1]. This release -fixes a security issue in Tahoe v1.1, fixes a few small issues in the -web interface, adds a "check health" operation for mutable files, and -adds logging/operations/deployment improvements. -See the known_issues.txt file [2] and the NEWS file [3] for details. +WHAT IS IT GOOD FOR? + +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]. + +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. + +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].) COMPATIBILITY -The version 1 branch of Tahoe is used as the basis of the consumer -backup product from Allmydata, Inc. -- http://allmydata.com . +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. + -Tahoe v1.2 is fully compatible with Tahoe v1.0. v1.2 clients produce -files which can be read by v1.0 clients. v1.2 clients can read files -produced by clients of all versions >= v0.8. v1.2 servers can serve -v1.0 clients and v1.2 clients can use v1.0 servers. +LICENCE -This is the third 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. +You may use this package under the GNU General Public License, +version 2 or, at your option, any later version.
