Amazon’s Simple Storage Service (S3) has a lot to like. It’s cheap, can be used for storing a little bit of data or as much as you want, and it can be used for distributing files publicly or just storing your private data. Let’s look at how you can take advantage of Amazon S3 on Linux.
Amazon S3 isn’t what you’d want to use for storing just a little bit of personal data. For that, you might want to use Dropbox, SpiderOak, ownCloud, or SparkleShare. Which one depends on how much data, your tolerance for non-free software, and which features you prefer. For my work files, I use Dropbox – in large part because of its LAN sync feature.
