Duplicati is a free backup client that securely stores encrypted, incremental, compressed backups on cloud storage services and remote file servers. It works with Amazon S3, Windows Live SkyDrive, Google Drive (Google Docs), Rackspace Cloud Files or WebDAV, SSH, FTP (and many more).

Duplicati uses AES-256 encryption (or GNU Privacy Guard) to secure all data before it is uploaded.

I had always been reluctant to store or backup some of my personals data in the cloud storage (privacy concern) until i discovered Duplicati !
Now, in addition to my local backups, i store some of them remotely and securely !

Just configure what you want to backup and Duplicati do the rest.

An example of remote backup (full + incremental) . The local source folder (~ 300 MB) is uploaded in several volumes (here, configured at 10 MB max each):

An example of the main GUI:

Website : http://www.duplicati.com/
License : LGPL
Dependencies : .NET 2.0+

Portable : Yes. Launch Duplicati.exe with the command-line --portable-mode (cf. Other protection measures)
Stealth : Yes.

Valuable informations are also available in the wiki (e.g: Some Background Information on how it started).

One cons. : sometimes the "Duplicati Wizard" can be non-user-friendly for modifying or updating settings of existing backups. But, according to the roadmap, a new GUI is planned.

Entry updated

Looks portable -- saving settings to the \data folder. Not stealth -- writes a "signature cache" to the AppData folder. If you're backing up a lot of data, this can really build up over time. Can be disabled in the options menu under Advanced (uncheck last item).

I haven't tested this out a great deal, but it's very promising.

Update: the signature cache is very useful. I modified the entry to suggest moving it to a temp folder to get stealth status.

When i read you, i had some doubts because the folder "signature cache" is in my folder \data .
I forget that i had modified the path with the environment variable %DUPLICATI_HOME% (cf wiki).

For "full stealth", you can configure like this.
Advanced Tab, section "Cache",

Temporary folder : %DUPLICATI_HOME%\temp
Signature cache: %DUPLICATI_HOME%\Signature Cache

About version. Last time i mistakenly updated the entry with version 1.3.2.1388, which is a "Development Snapshot". Currently, the last is 1.3.2.1452 (2012-08-23) (that i had not tested yet). The last stable release is 1.3.2 (2012-05-21).

Should we switch back the entry to 1.3.2 or keep update with last development snapshot version ?

Yeah that would work much better, although I wonder if the signature files are also relative (e.g. when you insert a USB drive, will the signature files recognize the drive letter change or give an error?).

With backup programs, most users are looking for stability and reliability rather than features. I'd recommend we push back to 1.3.2, unless this is could be considered a late beta.

Solved : 1.3.3 stable is out

By the way, if for some reasons you use symlinks in your backups (it's my case), caution:

In previous version the policy was "follow" now it's "store". Can be configured in the step "Manually override settings" in "Edit an existing backup".

Symlink handling.
Using this option to handle symlinks different. The "store" option will simply record a symlink with its name and destination, and a restore will recreate the symlink as a link. Use the option "ignore" to ignore all symlinks and not store any information about them. Previous versions of Duplicati used the setting "follow", which will cause symlinked files to be included and restore as normal files.

That works

I modified the entry to include the portable directory trick you pointed out. It seems like the users who don't want the signatures feature would probably just use a different backup tool entirely, so configuring that bit for portability seemed the only meaningful way to list that entry.

Duplicati 1.3.4 is available

Changes:

Added: Translations: Chinese, Hongkong, Russian translation

Added: Commands for command line can be exported from UI. (issue #236, Thanks to Nicolas Hatier). When you create a new backup job or edit an existing one, on the last page of the assistant you will get a tab that shows you the command to run the same job from a command line.

Various other fixes
