Navigating Disaster Recovery in the Digital Age: Choosing the Right Approach – Part 2
- Disaster recovery focuses on restoring data and systems after a disruptive event while backups simply preserve data against data loss.
- Six factors impact the decision-making process of selecting the right backup and disaster recovery (DR) solution.
- The primary goal of backups is to protect against data loss, while DR restores entire systems and applications so that business operations can resume as quickly as possible after a disruptive event.
- When designing a backup or disaster recovery (DR) solution, architects must determine whether the client needs a Backup solution, a Disaster Recovery solution, or both to avoid costly misalignments.
- AWS-native tools offer seamless integration and a comprehensive suite of tools. Third-party solutions provide advanced capabilities and flexibility, catering to specific use cases like hybrid environments or complex recovery requirements.
- Clients rely on architects to present comprehensive and unbiased recommendations. Demonstrating knowledge of both AWS-native and third-party options positions architects as a trusted advisor.
- In part three, the remaining four key considerations: RPO/RTO requirements, physical versus virtual servers, scheduling and automation, and the choice between on-premises and cloud restores will be discussed.
- Choosing the appropriate tools and processes to meet an organization’s recovery objectives is highly influenced by understanding the trade-offs of the available options.
- Finally, overdesigning for backups can be unnecessarily complex and expensive, while underestimating recovery needs can result in prolonged downtime and significant business losses.
- Having a clear understanding of the differences between Backup and DR, and evaluating AWS-native versus third-party solutions are foundational factors for an effective backup or DR solution.
