Original topic: tidb集群使用b r备份到Minio报错

[TiDB Usage Environment] Production Environment
Testing the backup using the br command failed. The specific command used is: tiup br backup full --pd=“10.200.78.51:2379” --storage=‘/data/backup/tidb’ --backupts=‘2023-04-14 11:10:00’
After executing the backup command, the screen started scrolling backup logs, and finally reported a backup failure. Could you please tell me if there is an issue with my backup command or if there is an internal cluster fault causing this? Or is there any other method to perform a full backup of the TiDB cluster database?

Finally, it was written that on the machine with IP 10.200.78.52, the path /data/backup/tidb could not be found.
BR requires that all TiKV nodes can access the specified path.

The path exists on 10.200.78.52, but it does not exist on the other two TiKV servers.

All TiKV nodes must have this path, and BR will place the SST files of this node onto this node.
