This section describes how to create, restore, and manage MySQL DB System backups. Only manual backups are supported; that is, you must create your backups following the instructions in Creating a Backup. Backups are not created automatically.
DB System backups are Amazon EBS snapshots which are automatically saved to Amazon Simple Storage Service (Amazon S3). MySQL HeatWave on AWS limits the maximum number of backups that you can retain across all DB System instances. If you reach the limit, remove the oldest backups before creating new ones.
It is recommended to create backups on a regular schedule. Backups are incremental, but if the period between backups is too long, a backup operation may take a long time to complete due to the volume of changes.
