Yes, I know that Amazon AWS EC2 is not certified by Oracle. However, zillions of people use it.
I've been asked to try setting up a fast recovery environment based on EBS volume snapshots. My tests so far show that if the whole database is on one volume, then a snapshot of the volume taken while the database is open does give me a database that works. I can mount it on another EC2 and start the instance: it recovers with the online redo and the database opens. So it seems that the snapshot is crash consistent. However, Oracle is not going to support this and Amazon will not give any guarantees either.
Does anyone have any experience they can share of using EBS snapshots like this? Does it always work, or have I just been lucky so far?
Thank you for any insight.
