In host-level DR, the production center and the DR center are networked for data transmission. A piece of specialized data replication software is installed on hosts on the production center and the DR center for remote replication. Common host replication software includes Symantec's Veritas Volume Replicator (VVR). In addition, some software has built-in remote replication function, for example, Oracle Data Guard.
To better implement remote replication, an application-based DR solution containing remote switchover software can be deployed on the host level. The host-level DR applies to scenarios where the host number is not large and is compatible with hosts and storage devices from multiple vendors, cutting the DR costs for customers whose hardware composition is complex. However, the host-level DR requires software running on hosts, which compromises the host performance.

Technology refers to the technologies used in the DR, such as data replication technology, application switchover, interface • DR site selection switchover, and service continuity. Select the DR site based on the disaster type. For example, in A DR system can be constructed by following four steps: service case of a fire, a flood, and an earthquake, the DR center can be analysis, policy making, implementation, and O&M management. several hundred meters, several miles, and several hundred miles At the early stage of the DR system construction, the first two away from the production center. Site selection varies with the steps are the focuses, which determine the complexity of the region. Ensure that all possible disasters are considered during site implementation and O&M management. selection.
Service Analysis • Date replication technology selection Service analysis consists of risk analysis and service impact The data replication technology, applying to the data replication analysis. between the production center and the DR center, is the core of a DR system. Huawei divides the data replication technology into Risk analysis covers possible organization and facilities host-level replication, SAN-level replication, and storage array- breakdowns caused by ambient environment factors, events having level replication. The host level consists of operating systems, adverse impact, and possible losses. In risk analysis, you need to applications, and databases. make countermeasures and corrective actions to reduce or prevent potential impact and losses. Moreover, you must make quantitative and qualitative evaluations on possible project risks, define risk levels based on the risk probability and risk impact, and determine focused protection scopes based on the risk level. Risk analysis provides basis for the follow-up policy making.
Service impact analysis quantifies and qualifies the impact of disasters and accidents. It helps you determine the criticality of different business systems and the DR priority and recovery time objective (RTO) for mission critical services and departments. Based on the service impact analysis, you can concentrate your investments to mission critical services. In service impact analysis, you must determine two key indicators: RTO and recovery point objective (RPO). RTO defines the length of time it takes to recover
