This topic describes the solutions to the issues that you may encounter when you use the backup feature of ApsaraDB RDS for MySQL.
How can I check the backup usage of an RDS instance?
You can go to the Basic Information page of the RDS instance to view the backup usage.
What does the backup usage consist of?
The backup usage consists of the backup storage that is used to store the backup sets and binary log files within the retention period.
Why is the backup usage of an RDS instance not reduced after I click Upload Binlogs to upload binary log files?
The Upload Binlogs feature is used to upload binary log files to which no data is written from the RDS instance to the specified Object Storage Service (OSS) bucket and delete the binary log files from the RDS instance. As a result, this feature cannot be used to reduce the backup usage.
How do I reduce the backup usage of an RDS instance?
You can use the following methods to reduce the storage usage of the RDS instance:
Reduce the number of days during which you want to retain backup files.
Reduce the backup frequency.
Scale up the disks of the instance.
