Cooking with Linux - Backing Up to the Clouds

Enough with the cloud nonsense. Sure, you can buy in to some big commercial cloud, but odds are you've already got one of your own. Why not take advantage of it and get yourself backed up safely?

A funny kind of cloud

This is a nice cookbook for backing up with rsync, but your "cloud" seems to be a single server. If the files aren't going to a highly redundant cluster of nodes, ideally spread across multiple buildings (better: cities; better: countries), I don't think I could call it a cloud.

I'd be really interested in hearing about an open source rsync service that backends on Hadoop or CouchDB or similar.

I use rsnapshot to automate backing up to a USB external drive. Symbolic links keep the size of each backup set to the minimum needed for changed files.
