What are common data backup and recovery solutions?
The data backup and recovery solutions vary by application scenarios and businesses. The following recommendations can be used based on your actual needs:

View the monitoring data regularly and configure corresponding alarms. For more information, please see Cloud Monitor. Process emergency requests with auto scaling.
