Infomaniak Cloud Sync : TooManyRequests

TrueNAS General

I’ve just setup Cloudsync for my TrueNAS Scale for offsite backups and I’m getting this error at the end. I’m using Swiss Backup from Infomaniak and using the S3 protocol.

[EFAULT] Checks: 177502 / 177502, 100%, Listed 673053 Transferred: 4318 / 4318, 100% Elapsed time: 50m52.6s 2026/06/08 05:56:18

https response error StatusCode: 429, RequestID: , HostID: , api error TooManyRequests: Too Many Requests

Is there something I can do for not getting that error?

  • I can’t add arguments for the Cloudsync.
  • Add something in the pre-script section?
  • Maybe doing a SYNC instead of a COPY when I PUSH ?

Same thing happens for me with Dropbox.
673053 files is probably simply to much.

IMHO, that is the problem with these “unlimited” plans and why I don’t like them.
As a provider, you offer API calls for free. Since it is free, you have to ratelimit it. Bad: you completly block it like in your case. Slightly better: you throttle it.

As a customer, I can’t know if and how I will be rate limited.

I would contact support and report back here.
