You can use the Commvault Cloud software to back up and restore a PostgreSQL app running in a Kubernetes cluster. To do this, install a Commvault Cloud container along with a PostgreSQL container inside a pod. Each pod in the Kubernetes cluster is registered as a client in the CommCell. Share the Data and Archive log directories in the persistent volumes (PV) with the Commvault Cloud container. Commvault Cloud is then able to read data for backups and write to volumes during restores.
The Commvault Cloud software also needs a 3 GB persistent volume to store its configuration files and logs. As the Commvault Cloud server does not know how to communicate with pods in a Kubernetes cluster, each pod can access a Commvault Cloud server through a one-way network topology immediately after the Commvault Cloud container in the pod is accessible. After the pod is registered as a client, you can create a PostgreSQL instance for each pod to run backups and restores. You can run the operations on both FS based backup set and Dump based backup set.
