Fault Recovery

GeminiDB can automatically create backups for your instances during the backup time window that you specified. The backups are stored based on the preset retention period (1 to 35 days).

Active-active DR

GeminiDB Redis allows you to create a dual-active relationship between two instances. Once one instance becomes faulty, the other takes over workloads to ensure service continuity.

Intra-region DR

Primary GeminiDB Cassandra instances support HA. If a primary instance fails to be connected due to a natural disaster, services can be switched over to its DR instance.

Cross-region Dual-active DR

GeminiDB Cassandra supports dual-active DR and bidirectional synchronization between two instances at different regions. Once one instance becomes faulty, the other takes over read/write traffic to ensure service continuity.

Multiple-AZ Deployment

An AZ is a physical region where resources have their own independent power supply and networks. AZs are physically isolated but interconnected over a private network. Nodes of one GeminiDB instance can be evenly deployed across three AZs to provide DR support.
