One of the critical aspects of managing your OpenSearch clusters is ensuring that your data is safely backed up and can be restored when needed. This article will delve into the details of implementing AWS OpenSearch backup.
AWS OpenSearch Service provides two types of backups: automated snapshots and manual snapshots. Both types are stored in Amazon S3, ensuring high durability and availability. If you want to learn the basics about snapshots in OpenSearch, check out this guide.
Restore from backups
Automated snapshots are enabled by default when you create an OpenSearch domain. These snapshots are taken daily and retained for 14 days at no additional cost. They are used for system-wide backups in case of a disaster recovery scenario.
Manual snapshots, on the other hand, allow you to take snapshots at your discretion. They are retained until you choose to delete them and can be used to migrate data across AWS accounts or regions.
Restoring data from an automated or manual snapshot
How to restore data from an automated or manual snapshot in OpenSearch?
- Navigate to the Snapshot Management section in OpenSearch Dashboards
- Click on the Snapshots menu
- Select the snapshot you want to restore data from and press the “Restore” button
- In the ‘Restore snapshot’ panel, choose the index or indexes that you want to restore
- Press the ‘Restore snapshot’ button.
Please note that restoring an index requires that index to be either closed or deleted first
In conclusion, AWS OpenSearch Service provides robust backup capabilities that can help you safeguard your data. By leveraging automated and manual snapshots, you can ensure that your data is protected and can be restored when needed.
