Fault Recovery

Resumable Data Transfer

To improve service availability and resilience, DRS provides resumable data transfer and fault recovery. If data in the source database is not corrupted or lost, the DRS instance can resume data transfer from the point at which the transfer was stopped.

Instance High Availability

An availability zone (AZ) is a physical region where resources use independent power supply and networks. AZs are physically isolated but interconnected over a local network. DRS also provides the cross-AZ HA. If the instance in the primary AZ becomes faulty, services can be switched over to the instance in the standby AZ to continue data replication.
