Virtualized disaster preparedness ensures data security
A large number of users' business systems rely on IT as support. If there are problems in the IT system environment, IT will be difficult to ensure the normal operation of the business and bring great losses. A variety of disaster recovery technologies and systems are popular in the market. However, due to the high installation, configuration, and complexity of the traditional disaster recovery system and its high price, 80% of the user's investment only protects 20% of the server, and can not really guarantee the operation of the business.
The purpose of disaster preparedness is to immediately restore the system and put it into use as soon as possible after a disaster occurs. Therefore, various technologies adopted in disaster preparedness, whether data backup, data replication, or other technologies, will be carried out around the business continuity. The indicators to measure these disaster Recovery technologies are mainly RPO (Recovery Point Object) and RTO (Recovery Time Object).
In a virtualization disaster solution, the target to be backed up is defined as a workload, which refers to the application running environment independent of the hardware platform, including the operating system, data, and applications.
The core idea of the disaster recovery solution of virtualization technology is bidirectional replication, where the data can be made available in real-time elsewhere. This copy can be put into use without data recovery, and then restored after interrupted recovery. The biggest benefit of data replication is that the replica data is immediately available, with no data recovery time, and RTO is perfect. Because it is replicated in real-time, the RPO is also perfect and almost no data is lost.
One of the most critical technologies in the virtualization disaster preparedness solution is the bidirectional migration technique. P2P migrates workload from one physical machine to another; P2V is the migration of a physical machine's workload to a virtualization platform. V2V and V2P are the migration of a virtual machine from one virtualization platform to another over a network, or the migration of a workload from one virtual machine to a physical machine.
The benefits of virtualization include the ease of recovering workloads in the event of system failures or disasters; Reducing the disadvantages of a disaster recovery solution that is expensive, typically requiring one-to-one redundant hardware and software resources; Better disaster preparedness and continuous testing can be easily completed to protect the workload in the mixed physical and virtual machines; When incremental replication is done, the network bandwidth can be set to prevent network bandwidth depletion, affecting other business operations.
If the physical server is completely broken, you can directly replace a new server and let the disaster recovery system to a new device. For example, when the primary server is upgraded and the server hardware configuration changes, then restore from the virtual machine can still be migrated to the new server or restored from the workstation to the blade.
In addition, the heterogeneous replication-based disaster preparedness technology is one of the future development trends and has a broader market. Because most customers have a heterogeneous host environment and support data replication technology in a heterogeneous environment, they can make use of the existing environment to replicate among each host, and virtualization is the solution to achieve this goal. However, when virtualization becomes mainstream today, we need to pay more attention to the data protection of the virtualization platform.
