Datameer and EMR instances are created with the Elastic Block Stores (EBS) volumes attached. The EBS Volumes are automatically replicated to protect you from component failure, offering high availability and durability. This enabled AWS to perform auto-recovery of the failed EC2 instances without any loss of data.

Datameer Enterprise version 7.2.8.1

Default deployment of Datameer Enterprise includes a local MySQL database ("DAP"). The database contains all metadata information relating to Datameer artifacts and must be backed up prior to upgrade and as part of Disaster Recovery strategy. The database backup should be stored in a location outside the EC2 instance where Datameer is running. Follow step-by-step guides to Backing Up and Restoring Datameer Database.

Datameer Enterprise version 7.4.4.1 and above

Datameer Enterprise is deployed in the high-availability environment to protect against component failure. Multi-AZ deployment within a region ensures resiliency of the infrastructure to disruption of a single AZ, so that Datameer will continue to operate in the case when all of the services within a single AZ have been disrupted. 

Default deployment of Datameer Enterprise includes a MySQL database ("DAP") that contains all metadata information relating to Datameer artifacts. The MySQL database is abstracted by Amazon Relational Database Service (Amazon RDS) that is deployed in the high-availability environment and automates hardware provisioning, database setup, patching and backups.
