Migration and upgrade of Snapshot Manager

Migrating Snapshot Manager

Users can manually migrate Snapshot Manager registered with NetBackup to Kubernetes Service cluster environment by performing the following steps:

Disable Snapshot Manager from NetBackup.
Stop services on the Snapshot Manager VM.

Create and attach a disk to the VM which will be used as PV for mongoDB:

Copy contents from /cloudpoint/mongodb to the new disk .
Copy flexsnap.conf and bp.conf configuration files to the VM from where cluster is accessible.
Detach the disk from VM and move it to cluster resources group (RG): MC_<clusterRG>_<cluster name>_<cluster_region>

From VM perform the following steps:

Create configuration maps using the following command:
kubectl create cm agentconf --from-file=<path to flexsnap.conf > -n <application namespace>
kubectl create cm nbuconf --from-file=<path to bp.conf>  -n <application namespace>
Create Snapshot Manager Secrets using the following command:
kubectl create secret generic cp-creds --from-literal=username='<username>' --from-literal=password='<password>'

Create mongodb Persistent Volume and Persistent Volume Claim as follows:

mongodb pv: 
 
apiVersion: v1 
kind: PersistentVolume 
metadata: 
  name: pv-azuredisk 
spec: 
  capacity: 
    storage: <Size of the disk> 
  accessModes: 
    - ReadWriteOnce 
  persistentVolumeReclaimPolicy: Retain 
  storageClassName: <Storage class name> 
  csi: 
    driver: disk.csi.azure.com 
    readOnly: false 
    volumeHandle: <Resource ID of the disk> 
    volumeAttributes: 
      fsType: <FS type> 
 
mongodb-pvc: 
apiVersion: v1 
kind: PersistentVolumeClaim 
metadata: 
  name: mongo-persistent-storage-flexsnap-mongodb-0 
spec: 
  accessModes: 
    - ReadWriteOnce 
  resources: 
    requests: 
      storage: <Disk size> 
  volumeName: pv-azuredisk 
  storageClassName: managed-csi

Edit the environment.yaml file to upgrade NetBackup (primary/media/MSDP) and add section for Snapshot Manager as follows:

cpServer: 
  - name: cp-cluster-deployment  
    containerRegistry: acr.azurecr.io 
    credential: 
      secretName: cp-creds 
    networkLoadBalancer: 
      annotations: 
        service.beta.kubernetes.io/azure-load-balancer-internal: "true" 
      ipAddr: 1.2.3.4 
      fqdn: cpserver.example.com 
  
    storage: 
      log: 
        capacity: 10Gi 
        storageClassName: standard 
      data: 
        capacity: <Disk size mentioned in mongodb pv> 
        storageClassName: <<Storage class name mentioned in mongodb pv> 
    nodeSelector: 
      controlPlane: 
        nodepool: cpcontrol1 
        labelKey: cp-node-label 
        labelValue: cpcontrol1 
      dataPlane: 
        nodepool: cpdata1 
        labelKey: cp-node-label 
        labelValue: cpdata1

Apply the environment.yaml file using the following command:
kubectl apply -f <path to environment.yaml>
Re-register the Snapshot Manger from WebUI if the Snapshot Manager name (fqdn/ip) is same as VM deployment.

Updating/Upgrading Snapshot Manager

Update:
User can update few parameters on the existing deployed Snapshot Manager by making changes in the cpServer section of environment.yaml file and apply it.
Only log size and data size fields can be changed in cpServer section of CR. For update operation to work, set the value of allowVolumeExpansion parameter to true in the storage classes used.
Upgrade:
If there is a change in the cpServer tag, then it would be considered as a Snapshot Manager upgrade. For upgrade only few parameters related to Snapshot Manager can be modified.

The following table lists the parameters that can be modified during update/upgrade of Snapshot Manager:

Parameters	Edit during update	Edit during upgrade
resourceNamePrefix	No	No
tag	No	Yes
containerRegistry	No	Yes
credential: secretName	No	No
networkLoadBalancer: annotations	No	Yes
networkLoadBalancer: fqdn	No	No
networkLoadBalancer: ipAddr	No	Yes
data.capacity	Yes	Yes
data.storageClassName	No	No
log.capacity	Yes	Yes
log.storageClassName	No	No
cpServer.NodeSelector.ControlPlane	No	Yes
cpServer.NodeSelector.DataPlane	No	Yes
