I have deployed Nifi on Kuberntes using cetic/helm-nifi helm chart. We are facing a problem, If nifi pod restarts we lost the all processes that we created. Is there any way to keep a backup of the process in nifi canvas.

You might be deploying the helm with default config or you are tweaking any configs also?
i have not used nifi but i think enabling the PVC config for nifi might resolve your resolve.
https://github.com/cetic/helm-nifi/blob/master/values.yaml#L211
You can enable the PVC by changing the values.yaml line number.
persistence:
enabled: true
if you have already created volumes you can also use it.
Nifi keeps flow definitions in the /opt/nifi/nifi-current/conf/flow.xml.gz file in the docker image. It is strongly advised to have /conf folder persist .There are lots of kubernetes alternatives for this . check the official document
You can also find archives in the /conf folder for back-ups
