I am experiencing many “We encountered an internal error. Please try again.” 5xx errors when trying to use R2 with backup tools like restic (e.g. “Save(<data/3578280506>) returned error, retrying after 711.218198ms: client.PutObject: We encountered an internal error. Please try again.”). This already caused a corrupted backup repository - is that a known issue or something wrong on my side?
Hey,
I’d recommend joining the Discord (Cloudflare Developers) where the R2 team is very active and can help you out 
Cloudflare R2 definitely shouldn’t be throwing internal errors but the fact that it caused a corrupt backup repository sounds like a client issue. IMO any robust backup software should be able to gracefully handle errors by retrying and eventually rolling back to a known-good state.
It looked like a PUT was acknowledged, but missing later, so I can’t really blame the client that data blocks are missing if this is the case. But I’ll do as @WalshyMVP suggested and have a look at discord
Interesting. It’s not good if a PUT was acknowledged with 200 OK but the object wasn’t actually written. I would mention this on Discord as well as it’s arguably a bigger problem than the internal errors.
