Using minio for full backup of TiDB, there was an error after completion. Is this normal? As follows:

Is this normal? There is data in minio. If it is not normal, what should I do? Thank you, everyone.

From the logs, it appears that the data was successfully backed up.

It’s unclear what the final update backup status is supposed to do. I guess it might be trying to update the backup result on backups.pingcap.com and failed due to network issues? This domain doesn’t seem to exist.

Since it ultimately printed that the update was successful, I think we can ignore this error.

Thank you for your response. It seems that we can only perform a recovery operation to verify the integrity.

I just checked the source code, it’s a trivial feature that will affect the user’s experience… I’ve already reported it.
