Disaster recovery - AWS Prescriptive Guidance

Disaster recovery

Many organizations implement high availability for their SQL Server databases, but that isn’t sufficient for organizations that require true IT resilience. We recommend that you implement a disaster recovery solution to avoid data loss and downtime of mission-critical databases. Adopting a multi-Region disaster recovery architecture for your SQL Server deployments help you:

  • Achieve business continuity

  • Improve latency for your geographically distributed customer base

  • Satisfy your auditing and regulatory requirements

Options for disaster recovery include log shipping, Always On availability groups, Amazon EBS snapshots that are stored in Amazon S3 and replicated across AWS Regions, Always On Failover Cluster Instances (FCIs) combined with Always On availability groups, distributed availability groups, and CloudEndure Disaster Recovery. The following sections describe distributed availability groups and CloudEndure Disaster Recovery.
