Backup and Restore

The Backup & Restore feature in M-FKE is designed to create snapshots of PVCs. M-FKE releases Backup & Restore version 1.0.0 with the following capabilities:

Backup Plan:

  • View the list of Backup Plans.
  • Create a new Backup Plan.
  • A single Backup Plan can be configured with multiple schedules for the system to automatically create PVC snapshots, applying to one or more PVCs at the same time.
  • Configure a Retention period in minutes, hours, or days.
  • Edit a Backup Plan.
  • Enable / Disable a Backup Plan.
  • Delete a Backup Plan.

PVC Snapshot:

  • View the list of PVC Snapshots (showing the creation method: Manually or Scheduled).
  • Sync the snapshot list from the cluster to FPT Cloud Portal.
  • Create a new PVC Snapshot.
  • Delete a PVC Snapshot.
  • Restore a PVC Snapshot.

PVC Restored:

  • View the list of restored PVCs.
  • Reload to update status.

Note: This feature applies to the Cinder driver (pre-created by FPT Cloud).

Create a Backup Plan​

Step 1: Go to Portal > Containers > Kubernetes > Cluster Details > Backup tab.

Figure 1: Backup Tab

Step 2: In the Backup tab, click New Plan to create a new Backup Plan.

Fill in the Backup Plan information, including:

① Essential Information:

  • Plan Name: name of the Backup Plan.
  • Retention: how long each snapshot is retained. After this period, the snapshot is permanently deleted.

② Schedule Scope:

  • PVC Backup List: list of PVCs in the cluster.

③ Schedules Information: enter specific month/day/year to schedule backups.

Note: Multiple Backup Plans can be created.

Figure 2: Enter the Plan name and select the Retention period (default 10 hours)

Note: Retention applies to the PVC snapshots selected in the Plan.

Figure 3: Select the PVCs you want to apply the Plan to

Note: The list is displayed as "pvc_name(pvc_namespace)".

Figure 4: Configure the desired schedules, add or remove as needed

Figure 5: Save the Backup Plan and return to the Backup tab

Figure 6: The newly created Backup Plan appears in the Backup Plan List

Figure 7: Edit / Disable / Delete a Backup Plan

Snapshots created according to the Backup Plan schedule appear in the Snapshot List with Type = "Scheduled".

Using the PVC Snapshot tab​

This sub-tab displays all created snapshots, including those created manually (Type = "Manually") or by a Backup Plan (Type = "Scheduled").

Figure 9: Select Create Snapshot to create a snapshot directly

Figure 10: Select Delete to delete, Refresh to update the latest snapshot status, and Restore to restore the PVC to the Kubernetes cluster

Figure 11: Use the Sync button to directly sync the status of Snapshots and PVCs from the Kubernetes cluster to FPT Cloud Portal

Using the PVC Restored tab​

When you restore a snapshot (Restore Snapshot) from the PVC Snapshot sub-tab, the restored PVC appears in the PVC Restored sub-tab.

Access your Kubernetes cluster and configure the deployment for the pod mapped to the restored PVC — the PVC status will then be updated.

Notes:

  • The number of snapshots per VPC is limited to a maximum of 10. To increase this limit, contact FPT Cloud Support.
  • Create Backup Plans carefully to avoid accumulating too many snapshots without deleting them, which can cause the infrastructure to reach its threshold and prevent new snapshots from being created.
  • If a Snapshot has a Failed status, access your Kubernetes cluster and run the following command to investigate the cause:
kubectl describe volumesnapshots.snapshot.storage.k8s.io <snapshot-name> -n <namespace>
