A company hosts a PostgreSQL database on an Amazon EC2 instance.

Use AWS Backup to automatically create backups of the EC2 instance. In the event of a database failure, use the backups to restore the EC2 instance to a second Region.

Use AWS DMS to migrate the database to an Amazon Aurora PostgreSQL database. Configure the Aurora database as a global database. Set the Aurora parameter group RPO setting to 60 seconds. In the event of a database failure, promote a secondary database in a second Region automatically.

Use AWS Elastic Disaster Recovery service to replicate the EC2 instance to a second Region. In the event of a database failure, use the Elastic Disaster Recovery dashboard to perform a failover.

Use AWS DMS to migrate the database to Amazon RDS for PostgreSQL. Create cross-Region read replicas in the Regions where most users are located. In the event of a database failure, manually promote a read replica to become the primary database.
