Recently My Website shifted on Amazon.

1. I create EC2 Instance. Install lamp and Setup CodeIgnitor in /var/www/http folder.
the structure
2. Codeignitor folder I have folder name 'UPLOAD'.this folder is used for uploaded images and files.
3. I make AMI image from EC2 Instance.
4. I have setup Auto scaling of Ec2 instances.
5. When my old ec2 instance is failed then automatically new instance is created. But My all data from "UPLOAD" of folder on old ec2 instance has lost.
6. I want to separate "UPLOAD" folder in codeignitor from ec2 instance. 
So whenever new instance is create it will get UPLOAD folder and its contents without loss.

I want to separate this upload folder. so when new instance is create then it will get this data.
how to do this.  

Thanks for Advance.

Note . I have used MYSQL on Amazon RDS.
