Why backup to Amazon S3 is a good idea?
Amazon S3 is storage for the Internet. Instead of dealing with backup tapes that you take off-site, you can backup and recover any amount of data, at any time, from anywhere on the web. Your backup data is securely stored on the same reliable, fast, and inexpensive data storage infrastructure that Amazon uses to run its own data centers. Amazon guarantees to provide commercially reasonable efforts to make Amazon S3 available with a Monthly Uptime Percentage of at least 99.9% during any monthly billing cycle.
