Elastic storage on AWS has a fairly low AFR (https://aws.amazon.com/ebs/details/ https://aws.amazon.com/ebs/details/): Amazon EBS volumes are designed for an annual failure rate (AFR) of between 0.1% - 0.2%, where failure refers to a complete or partial loss of the volume, depending on the size and performance of the volume. This makes EBS volumes 20 times more reliable than typical commodity disk drives, which fail with an AFR of around 4%. EBS also supports a snapshot feature, which is a good way to take point-in-time backups of your data.
