This is a simple way to backup your MySQL tables to Amazon S3 for a nightly backup - this is all to be done on your server :-)

Sister Document - Restore MySQL from Amazon S3 - read that next

this is for Centos 5.6, see http://s3tools.org/repositories for other systems like ubuntu etc

##Auto-deploy with php and github on an Ubuntu Amazon EC2 box

When ever it says www-data below, it's the user Apache runs under. So if your apache user is called something else, change it to that.

##Install git

sudo aptitude install git-core

Setup:

$ mongo
> use pubsub
> db.createCollection('messages', { capped: true, size: 100000 })
> db.messages.insert({})
