Create a backup

Create a file of the PostgresqlBackup resource, e.g., using the touch postgresqlbackup.yaml command.

Open the file and paste the configuration:

apiVersion: postgresql.stackland.yandex.cloud/v1alpha1
kind: PostgresqlBackup
metadata:
  name: cluster-backup
spec:
  cluster:
    name: cluster

Apply the manifest: kubectl apply -f postgresqlbackup.yaml -n <project name>. Optionally, you can specify the project name in the metadata.namespace resource property and skip it in the command.
