Which Items Occupy the Storage Space of My RDS for MySQL Instances?

Both your regular data (backup data not included) and the data required for the operation of your DB instances (such as system database data, rollback logs, redo logs, WAL logs, and indexes) take up storage space on your DB instances. The storage space includes the file system overhead required for inode, reserved blocks, and database operations. Binlogs generated by RDS for MySQL instances also occupy storage space.

These files ensure the stability of RDS DB instances.
