Aurora のバックアップについて

AWS

Backups
Aurora backs up your cluster volume automatically and retains restore data for the length of the backup retention period. Aurora backups are continuous and incremental so you can quickly restore to any point within the backup retention period. No performance impact or interruption of database service occurs as backup data is being written. You can specify a backup retention period, from 1 to 35 days, when you create or modify a DB cluster. Aurora backups are stored in Amazon S3.

If you want to retain a backup beyond the backup retention period, you can also take a snapshot of the data in your cluster volume. Because Aurora retains incremental restore data for the entire backup retention period, you only need to create a snapshot for data that you want to retain beyond the backup retention period. You can create a new DB cluster from the snapshot.
Note

  • For Amazon Aurora DB clusters, the default backup retention period is one day regardless of how the DB cluster is created.
  • You can't disable automated backups on Aurora. The backup retention period for Aurora is managed by the DB cluster.
