Just got around setting an automated backup to Amazon S3. Until now my backup was limited to Personal Computer -> Home Server -> External USB Drive all under one roof. Over the years I have gathered a lot of document clutter and have been lately scanning them and destroying the originals and that means that if the digital copy is gone then I am kaput. Having a copy on the S3 is good both backup wise and access from anywhere wise. Although I have setup my home server to be accessible from outside its still slow when downloading large files. As of now i have limited S3 to important stuff (just documents), I would eventually like to offload all my digital content o S3 (songs, pictures, videos etc) which would mean shelling more moola to Amazon. I wouldn't be accessing these content frequently so the cost is pretty much the storage cost and off-course the weekly rsync seeks. I also choose the 99.99% (0.10c/gb monthly) reliability over the 99.9999999% (0.15c/gb monthly) reliability as I am conformable with that given that I have a copy on my end too. S3 also has a special offer till Nov 1 wherein they are waving all "Data transfer In" fees. Below are some links that I used to setup :
