Snapshot and restore

MemoryDB for Redis clusters automatically back up data to a Multi-AZ transactional log, but you can choose to create point-in-time snapshots of a cluster either periodically or on-demand. These snapshots can be used to recreate a cluster at a previous point or to seed a brand new cluster. The snapshot consists of the cluster's metadata, along with all of the data in the cluster. All snapshots are written to Amazon Simple Storage Service (Amazon S3), which provides durable storage. At any time, you can restore your data by creating a new MemoryDB cluster and populating it with data from a snapshot. With MemoryDB, you can manage snapshots using the Amazon Web Services Management Console, the Amazon Command Line Interface (Amazon CLI), and the MemoryDB API.
