# Log backup
+ To start a log backup, run **`br log start`**
+ The log backup runs in the background, until stopped manually
+ A cluster can only run one log backup task each time

```
tiup br log start --task-name=pitr --pd "${PD_IP}:2379" \
--storage 's3://backup-101/logbackup?access-key=${access-key}&secret-access-key=${secret-access-key}'
```
