Backups let you restore your Memorystore for Valkey instances to a specificpoint in time. In addition, you can use backups to export and analyze data.

Backups are useful for the following scenarios:

• Disaster recovery: use backups as part of a disaster recovery plan. If adisaster occurs, then you can restore your data to a new Memorystore for Valkeyinstance.

• Data migration: migrate data between different Memorystore for Valkeyinstances. You can consolidate data or move it to a different region. You canalso restore backups from Memorystore for Valkey instances.

• Data sharing: share data between different teams or applications, enabling collaboration, offline data analytics, and data exchange.

• Compliance: create periodic backups of cache data for compliance purposes.

Backups and backup collections

Abackup is a point-in-time snapshot of your data. Backups are organized intobackup collections. Abackup collection includes all backups for a Memorystore for Valkey instance. If you delete an instance, then Memorystore for Valkey doesn't delete the corresponding backup collection automatically.

You can set a time to live (TTL) for a backup by setting a retention period.After the backup exceeds its TTL, Memorystore for Valkey deletes the backupautomatically.

To recover data in a backup, you cancreate an instance and seed the instance with data from the backup. However, youcan't import data into an existing instance.

Automated and on-demand backups

You can create backups in the following ways:

• Automated backups (Recommended): configure a backup schedule for aninstance. As a result, Memorystore for Valkey initiates periodic backupsfor the instance.

• On-demand backups: initiate a backup operation that begins immediately.

For more information about setting an automated backup schedule or initiating abackup, seeManage backups.
