Prerequisites for backup from snapshot and restore from backup operations
Label a valid storage class for NetBackup usage, add the following label:netbackup.veritas.com/default-csi-storage-class=true. If NetBackup labeled storage class is not found, then backup from snapshot job for metadata image and restore jobs fail with the error message No eligible storage classes found.
To label the storage classes, run the following commands given in the examples:
Example 1. Run the command:# kubectl get sc

Label a valid volume snapshot class for NetBackup usage, add the following label: netbackup.veritas.com/default-csi-volume-snapshot-class=true. If the NetBackup labeled VolumeSnapshotClass class is not found, then backup from snapshot job for metadata image and restore jobs fails with an error message: Failed to create snapshot of the Kubernetes namespace.
To label the volume snapshot classes, run the following commands given the examples:
Example 1. Run the command:# kubectl get volumesnapshotclass

Each primary server which runs the backup from snapshot and restore from backup copy operations, needs to create a separate ConfigMap with the primary server's name.
In the following
configmap.yaml
example,backupserver.sample.domain.com and mediaserver.sample.domain.com are the hostnames of NetBackup primary and media server.
IP: 10.20.12.13 and IP: 10.21.12.13 are the IP addresses of NetBackup primary and media server.
apiVersion: v1 data: datamover.hostaliases: | 10.20.12.13=backupserver.sample.domain.com 10.21.12.13=mediaserver.sample.domain.com datamover.properties: | image=reg.domain.com/datamover/image:latest version: "1" kind: ConfigMap metadata: name: backupserver.sample.domain.com namespace: kops-ns
Copy the
configmap.yaml
file details.Open the text editor and paste the yaml file details.
Then, save it with the yaml file extension to the home directory from where the Kubernetes clusters are accessible.
Specify
datamover.properties: image=reg.domain.com/datamover/image:latest
with correct datamover image.Specify
datamover.hostaliases
, if the primary server and the media servers connected to the primary server have short names and host resolution failing from datamover. Provide a mapping of all hostnames to IPs for primary and media servers.Create a secret as described in detail in the Point 6 in the Deploy service package on NetBackup Kubernetes operator section to use a private docker registry.
Once the secret is created, add the following attributes while creating a configmap.yaml file.
datamover.properties: |
image=repo.azurecr.io/netbackup/datamover:10.0.0049
imagePullSecret=secret_name
Create the
configmap.yaml
file, run the command: kubectl create -f configmap.yaml.If Kubernetes operator is not able to resolve the primary server based on short names
While fetching the certificates, if you get a message:EXIT STATUS 8500: Connection with the web service was not established. Then, verify the hostname resolution state from the nbcert logs.
If the hostname resolution fails, then do the following:
Update the kops deployment.yaml and add the hostAliases in the deployment.
In the following
hostAliases
example,backupserver.sample.domain.com and mediaserver.sample.domain.com are the hostnames of NetBackup primary and media server.
IP: 10.20.12.13 and IP: 10.21.12.13 are the IP addresses of NetBackup primary and media server.
hostAliases: - hostnames: - backupserver.sample.domain.com ip: 10.20.12.13 - hostnames: - mediaserver.sample.domain.com ip: 10.21.12.13
Copy, paste the hostAliases example details in the text editor and add to the hostAliases in the deployment.
Note:
The hostAliases section must be added to the line 2104 in default
./netbackupkops-helm-chart/templates/deployment.yaml
file.hostAliases example:
2104 hostAliases; - ip:10.15.206.7 hostnames: - lab02-linsvr-01.demo.sample.domain.com - lab02-linsvr-01 - ip:10.15.206.8 hostnames: - lab02-linsvr-02.demo.sample.domain.com - lab02-linsvr-02 imagePullSecrets: - name: {{ .values.netbackupKops.imagePullSecrets.name}}
Create a secret with fingerprint and authorization token.
Create a backupservercert request to fetch certificates.
