True, you're probably better off running the replication at the database layer, which can normally by either synchronous or asynchronous depending on what people need. For people who don't want to spend the money on a hot standby, you can still produce the database log files from MySQL (or whatever you're using), and copy them off the machine onto S3 every few seconds, minutes, etc. There's no end of solutions to the problem but, for whatever reason, a lot of people don't see EBS as a potential problem area.
