Backups in Managed Service for OpenSearch

Managed Service for OpenSearch supports automatic and manual index backups.

Creating backupsCreating backups

Backups are only created on running clusters.

Automatic backup takes place every hour, and you cannot turn it off. All automatic backups as well as all manually created backups are incremental and store only the data that has changed since the previous backup to save storage space.

After a backup is created, it is compressed for storage. The exact backup size is not displayed.

For more information about creating a backup manually, see Managing backups.

Storing backupsStoring backups

Storing backups in Managed Service for OpenSearch:

• Backups are stored in object storage as binaries.

• Automatic backups are stored for two weeks, and you cannot change that period. Manual backups are stored until the user deletes them.

• Backup storage is not subject to quotas or limits for cluster storage space.

• Backups are stored in object storage and do not take up space in cluster storage. If there are N free GB of space in the cluster, the storage of the first N GB of backups is free of charge.

  For more information, see the Managed Service for OpenSearch pricing policy.
