Configuring a Disaster Recovery Gateway
Scenarios
Before using a gateway and disaster recovery site servers for the first time, you need to configure the gateway.
Prerequisites
- The recommended ECS specifications to deploy the gateway are 8 vCPUs and 16 GB memory. Only Linux is supported. Huawei Cloud EulerOS 2.0 and EulerOS 2.9\2.10 are recommended, or see Supported OSs.
- The region, AZ, and VPC of the gateway ECS must be the same as those of the production site servers.
- It is recommended that you deploy the disaster recovery gateway and proxy client in the same security group and only allow ECSs within the security group to communication with each other. For details, see Security Group Configuration Examples.
- In 24.6.0 or an earlier version, ensure that you have upgraded the SDRS software on the gateway and production site servers to 24.9.0 or later and reconfigured the gateway according to the "Procedure for 24.9.0 or Later" part in this section.
In the following example, sdrs_linux_amd64_24.6.0.20240627203949.tar.gz is the package (24.6.0) used to configure the gateway.
- Run the following command in the /opt/cloud/sdrs directory to configure the gateway:
sh register_gateway.sh

- In cross-AZ scenarios, configure the following parameters:
