So we've got and AWS account and we've got acces to EC2 and S3. Now everything is fine and nice, and i want to backup some of the data on my EC2 instance (let's say /etc and /var/lib/mysql ) and some data from another server ( the company's emails beeing that data) .
We've got the right tools, so let's backup the data, we never know when we'll be happy that even if the data center was hit by a meteorite we've got all the data backed up and tommorow we'll have everything back and running. But , wait, i see e problem, and the problem is the S3 acces method (the credentials). I have only one account that i'm using for uploading my ec2 images (this beeing done by an automated script that takes a snapshot of the system from time to time), for uploading the /etc dir from my etc instance and /var/lib/mysql from the same instance , and for backing up the emails from the company mail server (which is outside amazon). If we would have more machines, we would have more stuff to backup from different places , so more machines would have the s3 credentials.
