You can begin backing up existing S3 buckets at any time; for example, if you upgraded an S3 configuration from a release earlier than ONTAP 9.10.1.

Before you begin

  • You have valid account credentials and configuration information for the object store provider.

  • Intercluster network interfaces and an IPspace have been configured on the source system.

  • The DNS configuration for the source storage VM must be able to resolve the target’s FQDN.

System Manager

  1. Verify that the users and groups are correctly defined:
    Click Storage > storage VMs, click the storage VM, click Settings and then click Edit icon under S3.

    See Add S3 users and groups for more information.

  2. Create an SnapMirror S3 policy if you don’t have an existing one and you don’t want to use the default policy:

    1. Click Protection > Overview, and then click Local Policy Settings.

    2. Click Arrow icon next to Protection Policies, then click Add.

    3. Enter the policy name and description.

    4. Select the policy scope, cluster or SVM

    5. Select Continuous for SnapMirror S3 relationships.

    6. Enter your Throttle and Recovery Point Objective values.

  3. Add a Cloud Object Store on the source system:

    1. Click Protection > Overview, then select Cloud Object Store.

    2. Click Add, then select Amazon S3 or Others for StorageGRID Webscale.

    3. Enter the following values:

      • Cloud object store name

      • URL style (path or virtual-hosted)

      • storage VM (enabled for S3)

      • Object store server name (FQDN)

      • Object store certificate

      • Access key

      • Secret key

      • Container (bucket) name

  4. Verify that the bucket access policy of the existing bucket still meets your needs:

    1. Click Storage > Buckets and then select the bucket you want to protect.

    2. In the Permissions tab, click Edit icon Edit, then click Add under Permissions.

      • Principal and Effect - select values corresponding to your user group settings or accept the defaults.

      • Actions - make sure the following values are shown: GetObject,PutObject,DeleteObject,ListBucket,GetBucketAcl,GetObjectAcl,ListBucketMultipartUploads,ListMultipartUploadParts

      • Resources - use the defaults (bucketname, bucketname/*) or other values you need.

        See Manage user access to buckets for more information about these fields.

  5. Back up the bucket using SnapMirror S3:

    1. Click Storage > Buckets and then select the bucket you want to back up.

    2. Click Protect, select Cloud Storage under Target, then select the Cloud Object Store.

When you click Save, the existing bucket is backed up to the cloud object store.
