Generally, two disaster recovery methods can be considered, activeactive mode and activestandby mode. The activestandby mode relies on two sets of environments, one as the main environment and the other as the backup environment. Under normal circumstances, the primary environment system provides services, and the other environment system does not bear any
traffic. Data is replicated synchronously between the primary Austria WhatsApp Number and secondary environments. Only when the main environment production system is paralyzed, the backup environment system will be switched to enable. The dualactive mode is also a business system with two environments. Different from the active and backup environments, the two environments will be running at the same time. It is similar to load balancing. The traffic direction can be controlled through tools, and the data synchronization is also realtime,
so it does not matter who is the one. It is the Lord who is prepared. The abovementioned disaster recovery levels and disaster recovery forms need to be considered when planning and designing disaster recovery solutions. Of course, all implemented solutions must be considered based on actual conditions. Do not overplan, and the appropriate one is the best. response mechanism After the implementation path is clear, an emergency response plan should also be developed, of which there are several key factors that require special attention.
