Due to NFS implementation specifics on certain NFS storage, backup job may fail with "rollback file deletion errors". Despite the error status, backups and replicas are created successfully, and required VRB files are deleted properly according to the retention policy. If you are experiencing this issue, here is the registry mod enabling jobs to ignore this error.
