[TiDB Usage Environment] Production Environment / Testing / PoC
[TiDB Version] 6.5.0
[Reproduction Path] First, perform a snapshot backup, then insert some data, then log backup, then snapshot restore, and finally log restore.
[Encountered Problem: Problem Phenomenon and Impact]
Found that the inserted data was not restored. After updating to version 6.5.6 of the br tool for log recovery, it directly reported an error.

Which version of the br tool does the official recommendation for log backup and recovery for this version?

Additionally, why was nothing restored, yet the final result returned as successful?

The official documentation indicates that the BR version should be the same as the TiDB version.

Brother, take a look at my description. The br log of version 6.5.0 didn’t recover, so I changed the version.

Is the data restored from the snapshot backup complete?
According to the official documentation, v6.5.0 should be the best recommendation.

  1. Please provide the cluster display results.
  2. Please provide the complete log, and check if there are any error-level messages before and after.

It should be the same version. If there are any issues, first check the cause of the problem.

I recommend using 6.5.0. Can you provide all the logs from the 6.5.0 recovery?
