Add cloud-based NFS backup locations

Portworx Backup allows you to add your cloud-based NFS targets as backup location. Refer the below topics to add EFS, GCP, and Azure cloud-based NFS targets as backup locations in your Portworx Backup.

Prerequisite

• Make sure that NFS packages are installed in all the worker nodes of all of your Kubernetes clusters before adding any of these cloud-based NFS backup locations.

Add EFS as NFS backup target

Prerequisite

Ensure that you have the required credentials and permissions to create EKS clusters and EFS volumes.

Create EFS volume on AWS

To add an EFS volume as NFS target, perform the following steps:

1. Create an EKS cluster on which you want to back up your data. If you are creating your first EKS cluster apply the following standard spec:

   apiVersion: eksctl.io/v1alpha5
   kind: ClusterConfig
   metadata:
         name: <cluster-name>
         region: <region-name>
         version: "1.26"
   managedNodeGroups:
         - name: storage-nodes
           instanceType: t3.2xlarge
           minSize: 4
           maxSize: 4
           volumeSize: 200
           amiFamily: AmazonLinux2
           labels: {role: worker, "px/node-type": "storage"}
           tags:
             nodegroup-role: worker
           ssh:
             allow: true
             publicKeyPath: ~/.ssh/id_rsa.pub
           iam:
             attachPolicyARNs:
               - arn:aws:iam::aws:policy/AmazonEKSWorkerNodePolicy
               - arn:aws:iam::aws:policy/AmazonEKS_CNI_Policy
               - arn:aws:iam::aws:policy/AmazonEC2ContainerRegistryReadOnly
               - arn:aws:iam::aws:policy/ElasticLoadBalancingFullAccess
               - arn:aws:iam::aws:policy/AWSMarketplaceMeteringFullAccess
               - arn:aws:iam::aws:policy/AWSMarketplaceMeteringRegisterUsage
               - arn:aws:iam::649513742363:policy/<other-policies-needed-for-cluster>
             withAddonPolicies:
               imageBuilder: true
               autoScaler: true
               ebs: true
               fsx: true
               efs: true
               albIngress: true
               cloudWatch: true
   availabilityZones: [ '<region-1>', '<region-2>', '<region-3>' ]

2. Once your first EKS cluster is ready, set up the second cluster with the following spec where you need to add your corresponding VPC and subnet details. This cluster can act as an application cluster:

   apiVersion: eksctl.io/v1alpha5
   kind: ClusterConfig
   metadata:
         name: <cluster-name>
         region: <region-name>
         version: "1.26"
   vpc:
         id: "<VPC-id>"
         subnets:
           private:
             us-east-1a:
                 id: "<subnet-id>"
             us-east-1b:
                 id: "<subnet-id>""
             us-east-1c:
                 id: "<subnet-id>"
           public:
             us-east-1a:
                 id: "<subnet-id>""
             us-east-1b:
                 id: "<subnet-id>""
             us-east-1c:
                 id: "<subnet-id>""
   managedNodeGroups:
         - name: storage-nodes
           instanceType: t3.xlarge
           minSize: 5
           maxSize: 5
           volumeSize: 200
           amiFamily: AmazonLinux2
           labels: {role: worker, "px/node-type": "storage"}
           tags:
           nodegroup-role: worker
           ssh:
             allow: true
             publicKeyPath: ~/.ssh/id_rsa.pub
           iam:
             attachPolicyARNs:
               - arn:aws:iam::aws:policy/AmazonEKSWorkerNodePolicy
               - arn:aws:iam::aws:policy/AmazonEKS_CNI_Policy
               - arn:aws:iam::aws:policy/AmazonEC2ContainerRegistryReadOnly
               - arn:aws:iam::aws:policy/ElasticLoadBalancingFullAccess
               - arn:aws:iam::aws:policy/AWSMarketplaceMeteringFullAccess
               - arn:aws:iam::aws:policy/AWSMarketplaceMeteringRegisterUsage
               - arn:aws:iam::649513742363:policy/<other-policies-needed-for-cluster>
           withAddonPolicies:
               imageBuilder: true
               autoScaler: true
               ebs: true
               fsx: true
               efs: true
               albIngress: true
               cloudWatch: true

3. Install EFS provisioner:

   kubectl apply -k "github.com/kubernetes-sigs/aws-efs-csi-driver/deploy/kubernetes/overlays/stable/?ref=release-1.3"

4. Copy and paste the below shell script in the terminal, update the name and region variables to create an EFS volume and attach the volume to the subnet.

   export cluster_name=<Name>
   export cluster_region=<Region>
   vpc_id=$(aws eks describe-cluster \
           --name $cluster_name \
           --query "cluster.resourcesVpcConfig.vpcId" \
           --output text --region $cluster_region)
   cidr_range=$(aws ec2 describe-vpcs \
           --vpc-ids $vpc_id \
           --query "Vpcs[].CidrBlock" \
           --output text --region $cluster_region)
   security_group_id=$(aws eks describe-cluster 
           --name $cluster_name 
           --query "cluster.resourcesVpcConfig.securityGroupIds[0]" --output text --region $cluster_region)
   aws ec2 authorize-security-group-ingress \
           --group-id $security_group_id \
           --protocol tcp \
           --port 2049 \
           --cidr $cidr_range --region $cluster_region
   file_system_id=$(aws efs create-file-system \
           --region $cluster_region \
           --performance-mode generalPurpose \
           --query 'FileSystemId' \
           --output text --region $cluster_region)
   aws ec2 describe-subnets \
           --filters "Name=vpc-id,Values=$vpc_id" \
           --query 'Subnets[*].{SubnetId: SubnetId,AvailabilityZone: AvailabilityZone,CidrBlock: CidrBlock}' \
           --output table --region $cluster_region

5. Copy the output from step 4, pick one subnet from each zone and add subnet values to the below command to create EFS mount target on the subnet:

   for subnet in <Subnet values>;do aws efs create-mount-target --file-system-id $file_system_id --subnet-id $subnet --security-groups $security_group_id --region $cluster_region;done

6. Copy the file system ID from Step 5, paste in the search field on the EFS page in AWS console and then click Attach. EFS page displays the file system details. For more information on creating EFS, refer Creating Amazon EFS.

7. Click Mount Via IP and provide the mount details.

Add Azure NFS file share as backup target

Prerequisite

• Install Azure CLI and login to the CLI.

• Ensure that you have required permissions to create resources.

Create NFS file share on Azure

Perform the below steps in Azure CLI to create an NFS file share on Azure cloud:

1. Create resource group to store the metadata of the resources:

   az group create  --name <resource-group-name> --location <location>

2. Create AKS cluster on which you want to back up your data :

   az aks create --resource-group <resource-group-name> --name  <cluster-name> --node-count 3 --node-resource-group <node-resource-group-name>

3. (Optional) Connect to the AKS cluster created in Step 2:

   az aks get-credentials  --resource-group <resource-group-name> --name  <cluster-name>

4. Enable service endpoint for Azure storage within the virtual network:

• Get the virtual network name:

  az network vnet list --resource-group  <node-resource-group-name> --query '[].[name]' --output tsv

• Get the subnet name:

  az network vnet subnet list --resource-group  <node-resource-group-name> --vnet-name <vnet-name> --query '[].[name]' --output tsv

• Provide the virtual network name and subnet name obtained from Step a and Step b in the following command to enable the service endpoint:

  az network vnet subnet update --resource-group <node-resource-group-name> --vnet-name <virtual-network-name> --name <subnet-name> --service-endpoints Microsoft.Storage

5. Create a storage account for your Azure NFS file share:

   az storage account create --location <location-name> -g <resource-group-name> --sku Premium_LRS --kind FileStorage -n <storage-account-name> --enable-sftp false --default-action Deny --https-only false

6. Obtain the subnet ID:

   az network vnet subnet list --resource-group  <node-resource-group-name> --vnet-name <vnet-name> --query '[].[id]' --output tsv

7. Add the network rule to the service account with the subnet ID obtained from Step 6:

   az storage account network-rule add -g  <resource-group-name>  --account-name <storage-account-name>  --subnet <subnet-id>

8. Create Azure NFS file share :

   az storage share-rm create -g <resource-group-name> --storage-account <storage-account-name>  --name <nfs-share-name> --quota <size-in-GB> --enabled-protocols NFS

9. Fetch the NFS server address:

   az storage account show --name <storage-account-name> --query primaryEndpoints.file

   Above command gives NFS server address in the following format:

   https://<storage-account-name>.file.core.windows.net/

   The string <storage-account-name>.file.core.windows.net and /<storage-account-name>/<nfs-share-name> serves as the NFS server address and NFS exported path respectively, to create NFS-based backup location in Portworx Backup.
