I've been looking in to using Amazon S3 as an offsite storage facility especially now that S3 is incorporated in WHM directly, but I can't make out the actual pricing to expect. I think I'd be in the $3/month range based on 100GB of standard storage and daily backups of about 10GB each day across about 30 cPanel user accounts (files). The S3 calculator for disaster recovery and backup has the pricing at nearly $1100/month.
I'm currently using FTP access into onlinefilefolder, but it keeps failing on two files that are over 2GB each. I got a deal with onlinefilefolder and paid something like $50 for 5 years or something. That was cheap enough for testing purposes, but I'm not afraid to pay a little for a solid solution.
I like owine's policy settings to use Glacier storage too. I'd probably keep stuff in Glacier indefinitely since there are always clients that crawl out of the woodwork after a few years and ask for something that is years old. "Sure, we can get that for you but it will cost $149.97."
Does the $3/month sound about right, or am I missing something? Do you have to have an EC2 instance or something to act as the "server" for the storage? I've seen some reports that S3 ended up being too expensive, but plenty others that say it is a great, cheap solution.
Thanks for the help.
