I am experimenting with EC2 spot instances, and am needing some data to be retained between terminations. Now as I understand it, when the current price goes above my max. bid, it will be automatically terminated. I assume any init scripts I have will be run on shutdown so I can push data off to the EBS before unmounting.

My question is, how can I automatically mount the same EBS volume on the new spot instance once the price goes down, since it won't have any of my init scripts that I would've loaded onto the root volume the first time?

Do I have to create a custom AMI, or is there some other way to achieve this?

This is a consumer app, so I will care about storage costs - I don't want to have 5x copies of data lying about. The app shards very well, so I can use MySQL and not have scaling issues.
