Overview

Asynchronous replication provides server-level protection if production site applications cannot be recovered within a short period of time due to force majeure (fire and earthquake) or device faults (faulty software and hardware). You can quickly recover services at the disaster recovery site with simple configurations.

Figure 1 shows the configuration process of asynchronous replication.

Figure 1 Configuration process

1. Set up a disaster recovery network on the cloud.

   Create VPCs and subnets on the cloud based on your disaster recovery plan.

2. Create a replica pair to establish the replication relationship between the production site and the disaster recovery site.
3. Deploy a cloud disaster recovery gateway.

   The cloud disaster recovery gateway aggregates, compresses, and encrypts the data on all replicated production site servers, and synchronizes the data to the disaster recovery site.

4. Download and install the proxy client.

   A proxy client transmits the data on the server to the cloud disaster recovery gateway.

5. Create protected instances.

   A protected instance consists of a server and its replicated server. The system automatically identifies the production site servers with proxy client installed. Create protected instances for the servers that require disaster recovery. After a protected instance is created, protection is automatically enabled for data synchronization.
