Today, we are excited to announce that Amazon EMR now supports backup and restore for your Apache HBase tables. For customers running Apache HBase databases on EMR, now with disaster recovery operations, you can easily ensure business continuity in case of a disaster as well as offer a higher resilience for workloads. This feature also allows Apache HBase administrators to easily perform common operational tasks like upgrading to the latest versions, rotating your clusters, and cleaning up old write ahead logs.
