Neptune Backups

Neptune backs up your cluster volume automatically and retains restore data for the length of the backup retention period. Neptune 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.

To control your backup storage usage, you can reduce the backup retention interval, remove old manual snapshots when they are no longer needed, or both. To help manage your costs, you can monitor the amount of storage consumed by continuous backups and manual snapshots that persist beyond the retention period. You can reduce the backup retention interval and remove manual snapshots when they are no longer needed.

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. Storing snapshots incurs the standard storage charges for Neptune. For more information about Neptune storage pricing, see Amazon Neptune Pricing.

Neptune retains incremental restore data for the entire backup retention period. So 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.

Important

If you delete a DB cluster, all its automated backups are deleted at the same time and cannot be recovered. This means that unless you choose to create a final DB snapshot manually, you can't restore the DB instance to its final state at a later time. Manual snapshots are not deleted when the cluster is deleted.

Note

• For Amazon Neptune DB clusters, the default backup retention period is one day regardless of how the DB cluster is created.

• You cannot disable automated backups on Neptune. The backup retention period for Neptune is managed by the DB cluster.
