In last September, I started to use Amazon S3 for some experimental purposes. And, it’s not that difficult — of course, I only use some basic action. CloudBerry Explorer and S3Fox are really helpful. Now, if you want to know the billing calculation — just in case you’re interested to try Amazon S3 (also with CloudFront), I have uploaded a sample billing statement from Amazon (click the thumbnail to enlarge).
For me, I think the price is still reasonable. Anyway, CloudFront service is optional. Of course, this billing statement is not only based on my blog usage. I have multiple sites and accounts there. Not all of my backup files are also available for public.
