Hi, The recommend way to do this is to use ES's built-in snapshot/restore feature [1]. You would probably want to store your backups in S3 rather than EBS.
Also note that EBS does not always provide an acceptable level of performance for low-latency queries. If you use EBS you most likely will want to use provisioned IOPS.
