Cheat sheet

This cheat sheet summarizes the key points from this chapter:

  • RPO is the maximum amount of data a company can lose without sustaining major damage.
  • RTO is the maximum amount of time a system can be unavailable without sustaining major damage.
  • RPO and RTO need to be considered together to define a backup and recovery strategy.
  • A recovery strategy can include backups, standby databases, read replicas, and manual scripts.
  • AWS Backup allows you to create centralized backup policies and plans to ensure that all your databases will meet your RTOs and RPOs.
  • AWS-managed databases offer maintenance windows that can be configured by the user to control the times that patching or other tasks that may cause a service disruption can run.
  • RDS daily backups run during a backup window, which should be set during the least busy times for the application to avoid performance impact.
