In the FusionCloud private cloud solution, the following is about the cloud server disaster recovery...

CSDR is a cross-region fire tolerance. When it needs to be used, at least two regions need to be planned. According to the two

The distance and delay of the Region can determine whether to use synchronous replication or asynchronous replication

Tenants can create their production business in any Region, and create placeholders in another Region

Virtual machine, occupying the private 1P address of the virtual machine is recommended to be consistent with the production virtual machine to reduce in-app virtualisation

Interaction between machines

The tenant creates a protection instance through the CSDR service, and it is recommended to protect all VMs in key applications to

Reduce the complexity of tenant business deployment and recovery

When a disaster occurs in a data center, the disaster recovery administrator logs in to BCManager eReplication

Manual failover of protection instances and manual startup of placeholder virtual machines
