TencentDB for SQL Server backup includes local backup and cross-region backup. The former stores the backup files of all TencentDB for SQL Server instances in a local region, while the latter stores backup files in a non-local region.
When you purchase TencentDB for SQL Server primary instances, you will receive free backup capacity. The backup space range is calculated separately for each region of an account. Excess backup files will be charged if your backup space exceeds the free tier. Note that the free tier is not applicable to cross-region backups, and as long as cross-region backup is enabled for your instances, all the generated cross-region backup files will incur fees.
This document describes backup fees. For more information, see:
