As part of our big infrastructure upgrade, we have improved our processes for database backups that are in addition to the AWS Aurora automated backups. The Aurora backups are good from a reliability point of view with features like enables point-in-time recovery. However, the backup is only good for 35 days and the time to recover is fairly long.
We have implemented a weekly full database backup and then incremental updates every half hour, which are all stored permanently. This will allow us to go back to any point in time if that is ever necessary. It will also allow us to deploy a new instance much more quickly if there is ever a disaster that we need to recover from.
