Wuala // is a secure online file storage, file synchronization, versioning and backup service originally developed and run by Caleido Inc., which is now part of LaCie. The service stores files in data centres that are provided by Wuala in multiple European countries (France, Germany, Switzerland). An earlier version also supported distributed storage on other users' machines, however this feature has been dropped.
||This section is in a list format that may be better presented using prose. (April 2012)|
14 August 2008: an "open beta"-java-applet, available from the website, could be run from a web browser.
16 December 2008: the Uniform Resource Locator changed from http://wua.la/ to http://www.wuala.com/ and files that were public, or shared through a keyed hyperlink, were made accessible through web browsers.
23 May 2011: all pro features - backup, sync, file versioning and time travel - are available for everyone at no cost
28 September 2011: The "trade storage" feature was discontinued.
Any registered user can:
- keep files private
- share files with other registered users
- share files with unregistered users, through a keyed hyperlink
- publish files
- file synchronization
- file versioning.
Registered and unregistered users can:
When a user adds a file to Wuala, or saves changes to a file that is served by Wuala, the user's local copy of file is:
- first encrypted
- then chunked into redundant fragments using Reed-Solomon error correction codes.
- The fragments are then uploaded to the data centers
Users of Wuala alone start with 5 GB of storage for free.
Users of joint products may start with greater amounts of storage for a limited period:
- with a LaCie external hard disk drive, 10 GB for one year
- with a LaCie USB flash drive, 4 GB for two years.
Additional storage may be bought, gained through referral.
For bought storage: prices range from 29 EUR/year for 20 GB to 999 EUR/year for 1 TB.
One of the distinguishing features of Wuala, the ability to trade local disk storage space against cloud storage is being discontinued.
The user interface offers most of the features that are normally associated with a file manager. Additional features come through integration.
- on any number of Linux, Mac OS X and Microsoft Windows computers
- with FUSE, MacFUSE and Dokan respectively for file system integration.
Wuala Webstart and web browsers
Through a web browser, on a computer that has Java installed:
- the user can start/trust a Java applet, which downloads and runs a class loader allowing fast start of the latest version of the Wuala application.
If the computer is without Java, or if running of the class loader is prevented:
- any folder that is public, or shared with a weblink, can be browsed.
Support for the following may be limited:
According to the FAQ, Wuala employs full client-side encryption. All files and their metadata get encrypted before they are uploaded. The encryption key is stored such that no one, not even LaCie that operates the service, can decrypt the stored files. The disadvantage of this is that Wuala has no password recovery and all data processing needs to be done in the client (for example creating a search index). The advantage is significantly improved privacy.
Since the source code to Wuala has not been released, it is difficult to ensure that the software does what it states it does (including proper client-side encryption). Also, updates are pushed automatically to the client machine. These facts mean that users of Wuala are not safe from possible backdoors in code.
