Replication Policy Management

Replication can be performed on buckets in a different location or the same location.
You can configure multiple replication policies, and if the source bucket becomes unavailable due to a failure or disaster, you can provide service through the replica bucket.

information
  • The replication feature operates in a 1:N structure, allowing replication within a region or between regions. * Data transfer charges are added when performing cross-region replication.
  • The replication feature applies only to files uploaded after the replication policy is set.
  • Deleting the versioned file in the source does not delete the files in the replica bucket.
    • Example: When set from Bucket A → Bucket B, even if the version file in Bucket A is deleted, it remains in Bucket B.
  • Bidirectional replication can be configured.
    • Example: When set to Bucket A ↔ Bucket B, files uploaded to Bucket A are replicated to Bucket B, and files uploaded to Bucket B are replicated to Bucket A.
  • The duplicated file will not be duplicated.
    • Example: When configured as Bucket A → Bucket B → Bucket C, files replicated from Bucket A to Bucket B are not replicated from Bucket B to Bucket C.
  • If there are no files in the original folder, that folder will not be duplicated as a copy.
Reference
The kr-south region does not provide inter-region Object Storage replication functionality.

  7. Click the Confirm button. 7. The replication policy modification is complete.

Caution

If an invalid policy exists, a replication policy cannot be added.

  • Example: If a replication bucket has a deleted policy remaining, you cannot add a replication policy.

Change Replication Policy Status

You can enable or disable the replication policy to change whether it is executed.

To change the replication policy status, follow these steps.

  1. Click the All Services > Storage > Object Storage menu. 1. Navigate to the Service Home page of Object Storage.
  2. On the Service Home page, click the Object Storage menu. 2. Go to the Object Storage List page.
  3. On the Object Storage list page, click the resource to change the replication policy status. 3. Object Storage Details Navigate to the page.
  4. Click the Clone tab.
  5. From the replication policy list, click the More > Enable or More > Disable button of the policy whose status you want to change. 5. A popup window opens to notify of a replication policy status change.
    • Enabled: Performs replication according to the replication policy.
    • Disable: Stop performing replication.
  6. Click the Confirm button. 6. The status of the replication policy changes.

Delete replication policy

You can delete unused replication policies.

Follow these steps to modify the replication policy.

  1. Click the All Services > Storage > Object Storage menu. 1. Navigate to the Service Home page of Object Storage.
  2. On the Service Home page, click the Object Storage menu. 2. Go to the Object Storage List page.

  6. Click the Confirm button. 6. The replication policy is being deleted.
Caution
  • If you change the versioning setting for the source and replica buckets, replication will not operate correctly.
    • If versioning on the source bucket is set to disabled, replication will not be performed. * If you set it to use again, it will replicate uploaded files from the point it was set.
    • If you set versioning of the replica bucket to disabled, replication will occur but versioning is not possible. * If you reset it to Use, version control will be applied from the point you set it.
  • If you delete the source bucket, the configured replication policy will also be deleted.
  • If you delete the replica bucket, the replication policy set on the source bucket remains.
    • If you recreate a replication bucket with the same name as a deleted replication bucket, replication will be performed to that bucket.

Activating ServiceWatch replication metrics

By default, Object Storage is integrated with ServiceWatch and basic monitoring. To link Object Storage replication metrics to ServiceWatch, you must enable ServiceWatch replication metrics. For detailed information about ServiceWatch, see the ServiceWatch 개요.

Caution
  • Basic monitoring is provided at no cost, but enabling replication metrics as a detailed monitoring item incurs additional fees.
  • The ServiceWatch replication metric, once set for a bucket, applies to all replication policies of that bucket.

To enable the ServiceWatch replication metric for Object Storage, follow these steps.

  1. Click the All Services > Storage > Object Storage menu. 1. Navigate to the Service Home page of Object Storage.
  2. On the Service Home page, click the Object Storage menu. 2. Go to the Object Storage List page.
  3. Object Storage List page, click the resource to enable ServiceWatch replication metrics. 3. Object Storage Details Navigate to the page.
  4. On the Object Storage Details page, click the Replication tab. 4. Go to the Clone tab.
  5. Click the Edit button for ServiceWatch replication metrics. 5. ServiceWatch Replication Metric Edit Navigate to the popup window.
  6. ServiceWatch Replication Metric Modification In the popup window, after selecting Enable, check the guidance text and click the Confirm button.
  7. Check the ServiceWatch replication metric items in the Replication tab.

Disable ServiceWatch replication metrics

Caution
Disabling the replication metric is necessary for cost efficiency. Keep the replication metric enabled only when absolutely necessary, and disable the replication metric otherwise.

To disable the ServiceWatch replication metric for Object Storage, follow these steps.
