AOSOPS02-BP02 Automate the process of taking snapshots
Schedule automatic snapshots to maintain consistent backups and data recoverability.
Level of risk exposed if this best practice is not established: Medium
Desired outcome: Snapshots are automatically created.
Benefits of establishing this best practice: To streamline snapshot management, use these features to schedule automatic snapshots at regular intervals, which allows for consistent data backups and recoverability in case of issues. By automating this process, you can reduce the risk of human error and minimize the impact of any unexpected events on your OpenSearch Service domains.
Implementation guidance
Amazon OpenSearch Service automatically creates hourly snapshots of your indices within the same domain. However, these automatic snapshots are not restorable across different domains.
If you rely solely on the automatic hourly snapshot, there's no need to follow this recommendation. However, if you prefer to take control of your snapshot schedule and have the flexibility to restore them in other OpenSearch Service domains, then continue following this best practice.
Implementation steps
Create a Snapshot Management (SM) policy:
-
Create a custom snapshot repository. For step-by-step instructions, see AOSOPS02-BP01.
-
Navigate to your OpenSearch Service domain dashboard.
-
In your OpenSearch Service dashboard, select Snapshot Management from the left-hand menu.
-
Create a new Snapshot Policy by choosing Create policy.
-
Configure policy details:
-
Name: Give your policy a unique name, for example
daily-snapshot-policy. -
Under Source and Destination boxes, select the indices that you want to snapshot, and choose the snapshot repository you registered (for example,
your-repository-name).
-
-
In the Snapshot schedule box:
-
Snapshot frequency: Enter how often you want snapshots taken. For example, choose daily if you want to back up every day.
-
Start time and Time zone: Enter the time of day and the time zone to take the snapshots.
-
-
(Optional) Define a retention policy to automatically delete older snapshots after a specific time period (for example, keep the last seven days).
-
Review the settings, then choose Create policy to save.
Once the policy is active, OpenSearch Service will automatically take snapshots based on your specified schedule, and they'll be saved in the designated Amazon S3 bucket.
