I've been looking to deploy my first rails app. I've decided to go with dedicated server, and move to cloud, if it grows large.<p>Since, the application will host user data, I want to be safe on hard disk crashes, Especially I want to backup databases.<p>Is it okey to have db on the same machine, or should I go for services like amazon rds for safety?<p>In case of backups, What solutions work well, to backup databases offsite?
