Data Protection
DCS takes different measures to keep data secure and reliable.

---|---|---|
DR and multi-active |
To meet reliability requirements of your data and services, you can deploy a DCS instance in a single AZ (single equipment room) or across AZs (intra-city DR). |
|
Data replication |
Data can be incrementally synchronized between replicas for cache data consistency. When a network exception or node fault occurs, a failover is automatically performed using the replicas. After the fault is rectified, a full synchronization is performed to ensure data consistency. |
|
Data persistence |
Exceptions may occur during daily running of the service system. Some service systems require high reliability, including high availability of instances, cache data security, recoverability, and even permanent storage, so that backup data can be used to restore instances if an exception occurs, ensuring service running. |
