Is there a required condition?\n\nAlways\n\n### What is the expected behavior? Why is that the expected behavior?\n\nzero should be rejected as an invalid rate, or explicitly treated as a documented single-call mode.\n\n### What do you see instead?\n\n```console\nbackup still pending after 1 second\n```\n\n`backup()` accepts `rate: 0` and its promise remains pending indefinitely while zero-page jobs are repeatedly scheduled.\n\n### Additional information\n\n_No response_","author":{"url":"https://github.com/trivikr","@type":"Person","name":"trivikr"},"datePublished":"2026-08-01T03:00:31Z","url":"https://github.com/nodejs/node/issues/64892"}
