The readiness re-gating guard read `r.Get(...) == nil` to mean "the Job does
not exist yet", folding any non-NotFound error (an apiserver hiccup, an RBAC
denial) into that branch. On such a transient error the driver would re-enter
the readiness precondition even though the Job may already exist and have
completed, reintroducing the spurious terminal failure this guard removes.
Switch on the Get error: nil means the Job exists (observe it), NotFound
means run the pre-launch readiness gate, and any other error requeues without
deciding. Same on the backup and restore paths.
