Allmydata.org "Tahoe" is a secure, decentralized, fault-tolerant
|
|
|
|
filesystem. All of the source code is available under a Free
|
|
|
|
Software, Open Source licence (or two).

|
|
|
This filesystem is encrypted and distributed over multiple peers in
|
|
|
|
such a way that it continues to work correctlly even when some of the
|
|
|
|
peers are unavailable, malfunctioning, or malicious.

This is the successor to Allmydata-Tahoe v0.7, which was released

|
This release improves performance, diagnostics, and packaging. This
|
|
|
|
release of allmydata.org "Tahoe" will form the basis of the next
|
|
|
|
consumer backup product from Allmydata, Inc. -- http://allmydata.com .

|
|
|
|
|
2008-02-14 15:54:34 +00:00
|
|
|
* Improve logging, diagnostic tools, statistics, timing measurements
|
|
|
|
during upload, etc..
|
|
|
|
|
2008-02-14 16:00:26 +00:00
|
|
|
* Add more measurements of performance:
|
|
|
|
http://allmydata.org/trac/tahoe/wiki/Performance .
|
|
|
|
|
|
|
|
* Add an upload helper, with resumption of incomplete uploads and
|
|
|
|
short-circuiting of uploads if the file is already present (tickets
|
|
|
|
#116, #258, #218).

|
|
|
|
clients-only and not publish themselves as servers (ticket #271).

|
|
|
|
mutable files if a long series of unlikely coincidences and hacked
|
|
|
|
clients occurred (ticket #312).
|

|
|
|

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 filesystem continues to work from the remaining
|
|
|
|
computers. You can also share your files with other users, using a
|
|
|
|
strongly encrypted, capability-based access control scheme.

2008-01-08 18:01:44 +00:00
|
|
|
This release is targeted at hackers and smart users who are willing to
|
|
|
|
use a web user interface, a command-line user interface, or a FUSE
|
|
|
|
interface. (Or a RESTful API. Just telnet to localhost and type HTTP
|
|
|
|
requests to get started.)

Because this software is new, it is not yet recommended for storage of
|
2008-01-08 18:01:44 +00:00
|
|
|
highly confidential data nor for valuable data which is not otherwise
|
|
|
|
backed up. However, it works well in practice, it comes with extensive
|
2008-02-14 16:00:26 +00:00
|
|
|
unit tests [2], and there are no known security flaws which would
|
2008-01-08 18:01:44 +00:00
|
|
|
compromise confidentiality or data integrity. (For a current
|
|
|
|
description of all known security issues and an overview of Tahoe's
|
2008-02-14 16:00:26 +00:00
|
|
|
security properties, please see the Security web page: [3].)

This release of Tahoe is suitable for the "friendnet" use case [4] --
|
|
|
|
it is easy to create a filesystem spread over the computers of you and
|
|
|
|
your friends so that you can share files and disk space with one
|
2008-01-08 18:01:44 +00:00
|
|
|
another.
