Schedule and Scope of Backup Capacity Billing
Excessive backup capacity will be charged for TencentDB for MySQL instances of High Availability Edition but not Basic Edition.
TencentDB for MySQL will charge for excessive backup capacity from October 2019 on. The specific schedule will be announced separately.
Backup capacity is used to store backup files of all TencentDB for MySQL instances in a region, including automatic data backups, manual data backups, and log backups.
TencentDB for MySQL offers a certain amount of backup capacity free of charge based on the region, which is equivalent to the sum of storage capacity of all HA instances (including master and disaster recovery instances) in your region.
Free backup capacity will be provided when you purchase a master or disaster recovery instance but not a read-only instance.
Excessive backup capacity will be charged at 0.000113USD/GB/hour in Mainland China and 0.000127USD/GB/hour in international regions.
If the excessive backup capacity or time period is less than 1 GB or 1 hour, they will be calculated as 1 GB or 1 hour, respectively. TencentDB for MySQL adopts a flexible giveaway policy, so that you generally do not need to pay for the backup capacity for most instances.
Free backup capacity in one region = Sum of storage capacity of all TencentDB for MySQL high availability instances in that region
Paid backup capacity in one region = Data backup volume + log backup volume - free backup capacity (all values are for that region)
TencentDB for MySQL instance backups in the recycle bin will also be calculated for the backup capacity.
If you have a running a TencentDB for MySQL high availability instance with a purchased database storage capacity of 500 GB/month in Guangzhou Zone 3 and another such instance with a purchased database storage capacity of 200 GB/month in Guangzhou Zone 4, you will get a free backup capacity of 700 GB/month in the Guangzhou region.
If your data backups reach 800 GB and log backups reach 100 GB, your total backup capacity in Guangzhou will exceed 700 GB, and your hourly paid backup capacity will be 200 GB per hour (800 + 100 - 700 = 200).
