Object Storage Service:RTC traffic fees

Last Updated:Aug 29, 2023

The Replication Time Control (RTC) feature of Object Storage Service (OSS) is developed based on the cross-region replication (CRR) feature and ensures that the time required to replicate data meets the service level agreement (SLA). After RTC is enabled for a single data replication task, OSS provides the data replication capability that meets the SLA for the data replication task. OSS also compensates for non-compliance based on the SLA.


This topic describes the billable items and billing methods of OSS. For more information, visit the OSS pricing page.
