It’s a strange error. It didn’t work last night, but it works this morning. Does anyone know what’s going on?

This log appearing is not an issue, it later shows “dump data successfully, dumpling will exit now.” This part is [info].

The previous logs are INFO, so this backup should have been successful, right?

Manually canceled? Or was it interrupted for other reasons?

After the backup is completed, start the GC safepoint through PD (the GC safepoint is stopped during the backup). This ERROR caused by context cancel after the backup is completed will be optimized in subsequent versions in terms of related logs and logic.
