Cross-Region Backup Billing

Last updated: 2026-03-20 16:02:37

Overview

This document describes how cross-region backup is billed. The cross-region backup feature is used to store backup files in another region. After this feature is enabled, local automatic backup files will be automatically copied to the COS bucket in the destination region.

Notes on Cross-Region Backup

Cross-region backup doesn't affect the local default backup, and both coexist after cross-region backup is enabled.
Cross-region backup will be triggered after the local default automatic backup is complete, that is, the default automatic backup is dumped to the storage device for cross-region backup.
Backup files in the cross-region backup space include automatic data backups and log backups, that is, local automatic backups are automatically synced to the destination region for storage.
Cross-region backups and local backups don't share the backup space.
Free space is unavailable for cross-region backups. As long as cross-region backup is enabled for the instance, all the generated backup files will incur fees.
Billable space of cross-region backups (for the region of the primary instance) = data backup volume (automatic backups in the destination region) + log backup volume (automatic backups in the destination region).
Cross-region backups are stored in the destination region, and the backup volume is counted in the backup space for the region of the primary instance. Cross-region backup storage and traffic fees are charged based on the destination region and the linkage between the source and destination regions respectively.

Cross-Region Backup Pricing

Cross-region backup fees consist of storage and traffic fees:
Cross-region backup fees = cross-region backup storage fees + cross-region replication traffic fees
For example, if an instance in Hong Kong (China) region is backed up to Beijing region, the cross-region backup will be stored in a COS bucket in Beijing region, the cross-region backup storage fees will be calculated at the storage price for Beijing region, and the cross-region backup traffic fees will be calculated based on the linkage between Hong Kong (China) and Beijing.

Storage pricing

Cross-region backup storage fees are charged in a pay-as-you-go (postpaid) manner at the storage price of the destination region as indicated below:
Chinese Mainland and Finance Zones
Hong Kong (China)
0.000113 USD/GB/hour
0.000127 USD/GB/hour
Note:
Billable space of less than 1 GB is not billed, and a billable time period of less than one hour is counted as one hour.

Traffic pricing

Cross-region backup traffic fees are charged based on the linkage between the source and destination regions in a pay-as-you-go (postpaid) manner at the prices as indicated below:
Source Region of Cross-Region Backup
Destination Region of Cross-Region Backup
Traffic Price (USD/GB/Hour)
Chinese mainland (Beijing, Shanghai, Guangzhou, Chengdu, Chongqing, and Nanjing)
Chinese mainland (Beijing, Shanghai, Guangzhou, Chengdu, Chongqing, and Nanjing)
0.09230769
Finance zones (Beijing Finance, Shanghai Finance, and Shenzhen Finance)

Cross-Region Backup Lifecycle

The cross-region backups of a running or isolated instance will be billed until it is deactivated.
Yearly/Monthly Subscription Instances
Within 7 days after the instance expires, if cross-region backup is enabled, the cross-region backup feature will operate normally.
After 7 days after the instance expires, namely starting from the 8th day after the instance expires, the instance will be isolated and moved to the recycle bin. At this time, rollback and manual backup will be prohibited, while automatic backups will still continue. If cross-region backup is enabled, it can also continue to synchronize normally, but modifications to the cross-region backup configuration will not be supported. You can renew your subscription in the console's recycle bin. Upon renewal, the instance and its backups, and the ability to modify cross-region backup configurations, will be restored.
After a 7-day isolation in the recycle bin, namely starting from the 15th day after the instance expires, the instance will be officially eliminated. At this time, the instance will be permanently terminated, along with all associated local and cross-region backups. Ensure necessary backups are saved promptly.
Pay-as-you-go instance
If cross-region backup is enabled, cross-region backups can be performed normally within 24 hours after the instance expires.
After 24 hours, the instance will be isolated into the recycle bin. At this point, rollback and manual backup will be prohibited, but automatic backup can still be performed normally. If cross-region backup is enabled, it can also be performed normally, but cross-region backup settings cannot be modified. You can renew the instance in the recycle bin in the console to recover it and its backups and modify cross-region backup settings.
After three days of isolation in the recycle bin (i.e., on the fifth day after expiration), the instance will be deactivated and terminated, along with all local and cross-region backups. Therefore, you need to save the required backup files promptly.

Payment Overdue

Yearly/Monthly Subscription Instances
If the instance has not yet expired but the account falls into arrears, backup-related services will be downgraded. Rollbacks, manual backups, and backup downloads will be prohibited. During this period, automatic backups will continue. If cross-region backup is enabled, it will proceed normally with backup synchronization and will be billed accordingly.
To perform services such as rollbacks, manual backups, backup downloads, and modify cross-region backup configurations, recharge your account to a positive balance.
Pay-as-you-go instance After your account has overdue payments, cross-region backup (if enabled) will change with the lifecycle of the instance. For more information, see the backup lifecycle of pay-as-you-go instances.
