ANNOUNCING Tahoe, the Least-Authority File System, v1.7.0β
|
|
|
|
(beta release for Tahoe-LAFS v1.7.0)
|
|
|
|
(This relnotes.txt document is the beta version of the
|
|
relnotes.txt document which will announce Tahoe-LAFS v1.7.0
|
|
when it is final.)
|
|
|
|
The Tahoe-LAFS team is pleased to announce the immediate
|
|
availability of version 1.7.0β of Tahoe-LAFS, an extremely
|
|
reliable distributed data store.
|
|
|
|
Tahoe-LAFS is the first cloud storage system which offers
|
|
"provider-independent security"—meaning that not even your
|
|
cloud service provider can read or alter your data without
|
|
your consent. Here is the one-page explanation of its unique
|
|
security and fault-tolerance properties:
|
|
|
|
http://tahoe-lafs.org/source/tahoe/trunk/docs/about.html
|
|
|
|
Tahoe-LAFS v1.7.0β is the successor to v1.6.1, which was released
|
|
February 27, 2010 [1].
|
|
|
|
v1.7.0β is a major new release with new features and a few bugfixes. It
|
|
adds a fully functional SFTP interface, support for non-ASCII character
|
|
encodings, and a new upload algorithm which guarantees that each file
|
|
is spread over multiple servers for fault-tolerance. See the NEWS file
|
|
[2] for details.
|
|
|
|
|
|
WHAT IS IT GOOD FOR?
|
|
|
|
With Tahoe-LAFS, you spread your filesystem across multiple
|
|
servers, and even if some of the servers fail or are taken
|
|
over by an attacker, the entire filesystem continues to work
|
|
correctly, and continues to preserve 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.
|
|
|
|
These related projects include frontends for Windows,
|
|
Macintosh, JavaScript, iPhone, and Android, and plugins for
|
|
Hadoop, bzr, mercurial, duplicity, TiddlyWiki, and more. See
|
|
the Related Projects page on the wiki [3].
|
|
|
|
We believe that strong encryption, Free and Open Source
|
|
Software, erasure coding, and careful engineering practices
|
|
make Tahoe-LAFS safer than RAID, removable drive, tape,
|
|
on-line backup or other Cloud storage systems.
|
|
|
|
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 currently known issues please see the
|
|
known_issues.txt file [4].)
|
|
|
|
|
|
COMPATIBILITY
|
|
|
|
This release is fully 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.
|
|
|
|
This is the ninth release in the version 1 series. The version
|
|
1 series of Tahoe-LAFS will be actively supported and
|
|
maintained for the forseeable future, and future versions of
|
|
Tahoe-LAFS will retain the ability to read and write files
|
|
compatible with Tahoe-LAFS v1.

SPONSORSHIP
|
|
|
|
Tahoe-LAFS was originally developed by Allmydata, Inc., a
|
|
provider of commercial backup services. After discontinuing
|
|
funding of Tahoe-LAFS R&D in early 2009, they have continued
|
|
to provide servers, bandwidth, small personal gifts as tokens
|
|
of appreciation, and bug reports. Thank you to Allmydata,
|
|
Inc. for their generous and public-spirited support.
|
|
|
|
Google, Inc. is sponsoring Tahoe-LAFS development as part of
|
|
the Google Summer of Code 2010. Google suggested that we
|
|
should apply for the Summer of Code program, and when we did
|
|
they generously awarded four sponsorships to students from
|
|
around the world to hack on Tahoe-LAFS this summer. Thank you
|
|
to Google, Inc. for their generous and public-spirited
|
|
support.
|
|
|
|
|
|
HACK TAHOE-LAFS!
|
|
|
|
If you can find a security flaw in Tahoe-LAFS which is serious
|
|
enough that feel compelled to warn our users and issue a fix,
|
|
then we will award you with a customized t-shirts with your
|
|
exploit printed on it and add you to the "Hack Tahoe-LAFS Hall
|
|
Of Fame" [12].

ACKNOWLEDGEMENTS
|
|
|
|
This is the fifth release of Tahoe-LAFS to be created solely
|
|
as a labor of love by volunteers. Thank you very much to the
|
|
team of "hackers in the public interest" who make Tahoe-LAFS
|
|
possible. In this release we especially owe thanks to
|
|
David-Sarah Hopwood, who has dedicated many late nights to the
|
|
project and displayed superb software engineering skills.
