In the Internet era, both large and small enterprises need infrastructure such as servers to deploy online business in their daily operations. To keep the business running stably and continuously, it is crucial to develop and implement an available disaster recovery plan. Because in the event of an unpredictable disaster, it will be a significant loss to the business. Disasters such as earthquakes may bring about problems such as power outages, collapse of server rooms and cabinets, cable damage, data loss, and many other issues, where tangible losses such as equipment damage can be compensated for, while losses caused by the loss of valuable data are incalculable.
We know that the bank’s data is very safe, there is no phenomenon such as data loss leading to the inability to withdraw money, in fact, this involves the problem of server disaster recovery, the bank in order to ensure the reliability of the data center, basically will be built in different cities each data center to place the server and storage data, usually one center work, the other two as a disaster recovery center, three data centers of data synchronization in real time The data in the three data centers are synchronized and updated in real time. This ensures that all cloud servers are not placed in the same place, and even if war or earthquake destroys the two centers, it will not affect the normal processing of banking business. In case of extreme conditions all three centers are destroyed, there is also offline backup data, data security is absolutely no problem to receive protection.
So what are some things we can do to keep our data safe?
The first thing you need to do to create a local data backup is to back up your hard drive storage. Next, you need to automate the backup. At this stage of the process, you need an image-based backup software that can take an incremental snapshot of the entire server, including the operating system and all applications and data. This way, everything can be fully restored to the same or another device, which saves a lot of time and money when any of the servers stop working.
Backing up to the cloud is even better than creating redundant backup drives. Why? Physical hard drive backups require personnel to be on the ground in the data center, and when organizations don’t have that, they leave online operations vulnerable. The most complete data backup system requires a combination of both methods. In this setup, locally redundant backup drives allow for quick backup and recovery from the most common disruptions, while image-based backups are securely stored in the cloud and help recover from more widespread disasters.
As an emerging disaster recovery approach in the disaster recovery field, cloud disaster recovery has matured to provide a proven solution for enterprises. Cloud disaster recovery is a model that considers disaster recovery as a service, and customers pay to use the disaster recovery services provided by the disaster recovery service provider. With this model, customers can take advantage of the service provider’s superior technical resources, rich experience in disaster recovery projects and mature operation and maintenance management processes to quickly achieve their disaster recovery goals, reduce their operation and maintenance costs and work intensity, and lower the total cost of ownership of disaster recovery systems.
However, there are also many areas that need attention in the development of cloud disaster services, such as subscription fee model, on-demand subscription, flexible capacity expansion, reducing the initial investment waste; no initial hardware asset investment and operation and maintenance personnel investment; to meet the user ready to use, simple operation, and delivered to the user in a cloud management mode.
In the construction of disaster recovery and backup system, data backup is the key and the foundation. Do a good job in the construction of disaster backup, through effective disaster recovery mechanism, in order to ensure the business continuity of the enterprise and reduce the loss brought to the enterprise because of data loss, etc.
