Chapter 6. Mirroring data for hybrid and Multicloud buckets
Chapter 6. Mirroring data for hybrid and Multicloud buckets The Multicloud Object Gateway (MCG) simplifies the process of spanning data across cloud provider and clusters. Prerequisites You must first add a backing storage that can be used by the MCG, see Chapter 4, Adding storage resources for hybrid or Multicloud . Then you create a bucket class that reflects the data management policy, mirroring. Procedure You can set up mirroring data in three ways: Section 6.1, "Creating bucket classes to mirror data using the MCG command-line-interface" Section 6.2, "Creating bucket classes to mirror data using a YAML" Section 6.3, "Configuring buckets to mirror data using the user interface" 6.1. Creating bucket classes to mirror data using the MCG command-line-interface From the Multicloud Object Gateway (MCG) command-line interface, run the following command to create a bucket class with a mirroring policy: Set the newly created bucket class to a new bucket claim, generating a new bucket that will be mirrored between two locations: 6.2. Creating bucket classes to mirror data using a YAML Apply the following YAML. This YAML is a hybrid example that mirrors data between local Ceph storage and AWS: Add the following lines to your standard Object Bucket Claim (OBC): For more information about OBCs, see Chapter 9, Object Bucket Claim . 6.3. Configuring buckets to mirror data using the user interface In the OpenShift Web Console, click Storage OpenShift Data Foundation . In the Status card, click Storage System and click the storage system link from the pop up that appears. In the Object tab, click the Multicloud Object Gateway link. On the NooBaa page, click the buckets icon on the left side. You can see a list of your buckets: Click the bucket you want to update. Click Edit Tier 1 Resources : Select Mirror and check the relevant resources you want to use for this bucket. In the following example, the data between noobaa-default-backing-store which is on RGW and AWS-backingstore which is on AWS is mirrored: Click Save . Note Resources created in NooBaa UI cannot be used by OpenShift UI or Multicloud Object Gateway (MCG) CLI.
