Go to the /root directory at 21:30 every day and upload the /src/src1 folder to bucket obs://bucket-test in the incremental mode.

You have properly enabled the scheduled crond service in the Linux OS.

NOTE:

Run the service crond status command to check whether the service is enabled.

Run the crontab -e command to open the configuration file for setting a scheduled task.
Enter the Insert mode to edit the configuration file.
```
30 21 * * * cd /root && nohup ./obsutil cp /src/src1 obs://bucket-test -r -f -u &>obsutil_crond.log &
```
NOTE:

Assume that the obsutil tool is in the /root directory. The preceding configuration is described as follows: Go to the /root directory at 21:30 every day, upload the /src/src1 folder to bucket obs://bucket-test in incremental mode, and redirect the command output to the obsutil_crond.log file in the /root directory.
Press Esc to exit the Insert mode. Then input :wq and press Enter to save the configuration and exit.
Run the crontab -l command to check whether the scheduled task is configured successfully.

How do I determine whether a scheduled task is being executed?
- Run the tail /var/log/cron command to view the latest scheduled task execution records.
- Run the ps -ef | grep obsutil command to check whether obsutil is being executed.
How do I forcibly stop an ongoing scheduled task?
1. Run the ps -ef | grep obsutil command to check the process of obsutil.
2. Run the kill -9 PID command to forcibly stop the process, where PID indicates the queried process ID.
