      Description of problem:

      We found this issue during the interop testing, OCP 4.14 has pod Security mode set as enforce which caused the pod to be getting denied. This is caused due to the restore order, basically the pod is getting created before the SCC resource as this pod violates the podSecurity standard it denies the pod.

      I have tested it with setting restore priority field on velero server, restore was successful. 

      $ oc get dpa -o yaml
         configuration:
            restic:
              enable: true
            velero:
              args:
                restore-resource-priorities: ServiceAccount,SecurityContextConstraints
              defaultPlugins:
              - gcp
              - openshift
      
      $ oc get restore -o yaml

        backupName: test-restic

      OCP 4.14 
      OADP 1.1.4 

       

      How reproducible:
      Always

      Steps to Reproduce:
      1. Deploy an application which consist SCC resource.

      $ oc create -f https://raw.githubusercontent.com/openshift/oadp-operator/master/tests/e2e/sample-applications/mysql-persistent/mysql-persistent.yaml

      2. Execute backup with restic.

      $ cat backup.yml 
      apiVersion: velero.io/v1
      kind: Backup
      metadata:
        name: test-restic
        labels:
          velero.io/storage-location: default
        namespace: openshift-adp
      spec:
        defaultVolumesToRestic: true
        includedNamespaces:
        - mysql-persistent
        storageLocation: ts-dpa-1

      3. Delete app namespace
      4. Execute Restore

       

      Actual results:

      Restore is partially failing.

      Expected results: 
      Restore should be successful.
