Chapter 6. Mirroring data for hybrid and Multicloud buckets

From the MCG command-line interface, run the following command to create a bucket class with a mirroring policy:

$ noobaa bucketclass create mirror-to-aws --backingstores=azure-resource,aws-resource --placement Mirror

Set the newly created bucket class to a new bucket claim, generating a new bucket that will be mirrored between two locations:

$ noobaa obc create  mirrored-bucket --bucketclass=mirror-to-aws

Apply the following YAML. This YAML is a hybrid example that mirrors data between local Ceph storage and AWS:

apiVersion: noobaa.io/v1alpha1
kind: BucketClass
metadata:
  name: hybrid-class
  labels:
    app: noobaa
spec:
  placementPolicy:
    tiers:
      - tier:
          mirrors:
            - mirror:
                spread:
                  - cos-east-us
            - mirror:
                spread:
                  - noobaa-test-bucket-for-ocp201907291921-11247_resource

Add the following lines to your standard Object Bucket Claim (OBC):

additionalConfig:
  bucketclass: mirror-to-aws

For more information about OBCs, see Chapter 8, Object Bucket Claim.

In your OpenShift Storage console, navigate to Overview Object Service select the Multicloud Object Gateway link:

Click the buckets icon on the left side. You will see a list of your buckets:

Click Edit Tier 1 Resources:

Select Mirror and check the relevant resources you want to use for this bucket. In the following example, we mirror data between on prem Ceph RGW to AWS:
