True. However, for some cases where you don't mind losing some data due to a recovery process EBS snapshots are 'good enough'. Additionally, with a database like CouchDB with a 'crash only' design, it should work for some cases as well.

We use EBS snapshots as a last-resort backup. They're really convenient that way. We have a more robust backup system, but in the unlikely event that something goes wrong at least we have those snapshots, even if they're not perfect.
