What does the AWS disaster recovery model primarily rely on?

The AWS disaster recovery model primarily relies on backups and snapshots in multiple availability zones because this approach enhances resilience and ensures that data is secure against outages and disasters. AWS offers multiple availability zones within each region, which are effectively isolated from each other but can still communicate. This design allows for effective disaster recovery strategies, as data can be replicated and backed up across these zones.

By utilizing multiple availability zones, organizations can ensure that if one zone experiences a failure, they can quickly recover their data from backups and snapshots stored in another zone, thus minimizing downtime and data loss. This multi-zone strategy also creates redundancy for critical systems, allowing applications to remain operational even in adverse conditions.

The focus on backups and snapshots also highlights the importance of regular data protection measures within the AWS infrastructure, ensuring that users can restore their systems to a recent state with the required data intact. This approach contrasts with relying solely on redundancy in a single location, which could still lead to total data loss in the event of a catastrophic failure at that specific site.
