A few weeks ago, Amazon announced a new feature for EBS snapshots: Amazon EBS Fast Snapshot Restore (FSR). Normally, accessing data on new EBS volumes was quite slow as the data is lazy-loaded from S3. When Fast Snapshot Restore (FSR) has been enabled on an EBS snapshot, new EBS volumes created from that snapshot will allow fast data access. While this feature is very good, it’s very expensive to keep enabled on an EBS snapshot for a long time.
