Original topic: br 备份报错无法成功备份出来

| username: blaine

[TiDB Usage Environment] Production Environment
[TiDB Version] 5.3.0
[Encountered Issue] br backup reports that the tikv node cannot find the path
[Reproduction Path] No other operations were performed. Initially, it was backed up locally and reported an error, thinking it was a path issue. Then switched to an NFS shared disk and also reported an error.
[Issue Phenomenon and Impact]
An error is reported after the backup, and part of the SST file has already been backed up in the backup path. However, it eventually exited without completing normally.
One TiKV machine has 2 TiKV instances. Could this be the reason? Is there a solution?

The BR log error is as follows:

[BR:KV:ErrKVStorage] tikv storage occur I/O error
error happen in store 4 at 200.200.11.117:20161: Io(Os { code: 2, kind: NotFound, message: “No such file or directory” })

It roughly means that the TiKV at 200.200.11.117:20161 cannot find the backup directory. Please check if the NFS is correctly configured on the corresponding machine.
Also, please check the TiKV logs to confirm the cause of the error.
