The cluster has recovered from the network partition failure, but the checkpoint of the log backup task progress still does not resume. Why?

Issue: #13126

After a network partition failure in the cluster, the backup task cannot continue backing up logs. After a certain retry time, the task will be set to ERROR state. At this point, the backup task has stopped.

To resolve this issue, you need to manually execute the br log resume command to resume the log backup task.
