Procedure

   1. In the OpenShift Dedicated web console, change into the Administrator perspective.
   2. Click Home Projects.

   3. Click the rhods-notebooks project.

      The Details page for the project opens.

      The PersistentVolumeClaims page opens.

   5. Note the ID of the persistent volume (PV) that you want to back up.

      Note

      The persistent volumes (PV) that you make a note of are required to identify the correct EBS volume to back up in your AWS instance.

2. Locate the EBS volume containing the PVs that you want to back up.

   See Amazon Web Services documentation: Create Amazon EBS snapshots for more information.

   1. Log in to AWS (https://aws.amazon.com) and ensure that you are viewing the region that your OpenShift Dedicated cluster is deployed in.
   2. Click Services.
   3. Click Compute EC2.

   4. Click Elastic Block Storage Volumes in the side navigation.

      The Volumes page opens.

   5. In the search bar, enter the ID of the persistent volume (PV) that you made a note of earlier.

      The Volumes page reloads to display the search results.

   6. Click on the volume shown and verify that any kubernetes.io/created-for/pvc/namespace tags contain the value rhods-notebooks, and any kubernetes.io/created-for/pvc/name tags match the name of the persistent volume that the EC2 volume is being used for, for example, jupyter-nb-user1-pvc.

3. Back up the EBS volume that contains your persistent volume (PV).

   1. Right-click on the volume that you want to back up and select Create Snapshot from the list.

      The Create Snapshot page opens.

   2. Enter a Description for the volume.

   3. Click Create Snapshot.
