Chapter 10. Backing up data

Procedure

1. Determine the IDs of the persistent volumes (PVs) that you want to back up.

   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.

   4. Click the PersistentVolumeClaims in the Inventory section.

      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 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 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.

      The snapshot of the volume is created.

   4. Click Close.

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

      The persistent volume (PV) IDs are required to identify the correct persistent disk to back up in your GCP instance.

2. Locate the persistent disk containing the PVs that you want to back up.

   1. Log in to the Google Cloud console (https://console.cloud.google.com) and ensure that you are viewing the region that your OpenShift Dedicated cluster is deployed in.
   2. Click the navigation menu (≡) and then click Compute Engine.

   3. From the side navigation, under Storage, click Disks.

      The Disks page opens.

   4. In the Filter query box, enter the ID of the persistent volume (PV) that you made a note of earlier.

      The Disks page reloads to display the search results.

   5. Click the disk 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 persistent disk is being used for, for example, jupyterhub-nb-user1-pvc.

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

   1. Select CREATE SNAPSHOT from the top navigation.

      The Create a snapshot page opens.

   2. Enter a unique Name for the snapshot.
   3. Under Source disk, verify the persistent disk you want to back up is displayed.
   4. Change any optional settings as needed.

   5. Click CREATE.

      The snapshot of the persistent disk is created.
