Backblaze cloudsync task fails with 503 error

[Penobscot]

I receive the following intermittently:
[EFAULT] Checks: 804 / 804, 100% Transferred: 16 / 16, 100% Elapsed time: 36m49.9s 2023/12/05 02:06:51 Failed to sync with 2 errors: last error was: no tomes available (503 service_unavailable)

Backblaze's solution to a 503 error is simple: try again.

Would this code, using --retries, work? Thanks
