[Test Environment for TiDB]
[TiDB Version] v8.1.0
[Reproduction Path] tiup br log start --task-name pitr --pd -s local:/backup
[Encountered Issue: Error: [pd] failed to get cluster id

(There is no problem with the full database backup, /backup is an NFS share)

It should be written like this, right?
tiup br log start --task-name=pitr --pd “” --storage “local:///backup”

–pd Is this address correct? It looks like the address in the command is wrong.

Modify the command as follows:
tiup br log start --task-name=pitr --pd=“${PD_IP}:2379” --storage=‘local:///backup’

In addition, tiup br log status --task-name=pitr --pd=“${PD_IP}:2379” is used to query the task status.
