Nice T-shirt, eh? Yeah, it’s been around for awhile, having been part of one of Mozy’s (the online backup firm) promotions a few years back. It’s a great double entendre (not to mention the eye candy) and really punches home the need for backups. Which is what this post is about. Specifically, it’s about Duplicati, 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 is licensed under LGPL (if you don’t know the difference between this and the GPL, well, better find out) and is available for Windows, Linux and, as of May 2012, MacOS in several languages. AES-256 encryption is built in and GNU Privacy Guard is also available. The latest version is 1.3.2.
It took me less than a minute to download and install with the defaults, but you’ll probably want to turn off the translations unless you speak several languages. After installation, the Duplicati Setup Wizard let me set up a new backup. For test purposes, I selected “Custom folder list” for my backup. After that, I was taken to the “Select password for the backup” screen. Here, you can choose the encryption method you want and set a good password. You can click the magic wand button to generate a super-strong password, or you can use one of your own. I chose to run the backup immediately and everything went smoothly.
Restoring from backup is straightforward: just click the Duplicati tray icon, open the wizard and follow the instructions.
It doesn’t get much easier than that to produce reliable, secure backups.
