The storage of a domestic bank was paralyzed, and data loss caused huge economic losses.

According to a media source: a storage equipment failure in a domestic bank's production center caused long-term interruption of multiple systems, including core business systems, and the counter and electronic channel businesses were greatly affected. The bank's production center storage equipment (a foreign brand) triggered a fiber bridge firmware program defect due to the capacity expansion operation, causing a large number of disk failures in a short period of time. The two controllers that were backups of each other worked chaotically at the same time, and data could not be read or written. , core, counter and other systems stopped running.

The storage device also carries data from dozens of information systems in the bank's virtualization platform. This resulted in more than 6 hours of business loss.

For banks, 6 hours of data loss is a huge loss for today’s banking business that relies on all kinds of data. Therefore, in today's era of data economy, while enterprises are enjoying the dividends brought by information technology, how to reasonably manage, control, store, and back up data has become their most urgent demand. Let me talk about Haiyu.com today. What is a more scientific and reasonable data disaster recovery and backup mechanism for banks and other financial companies?

In the past, data protection may have been more focused on individuals, network security, personal privacy security, business secrets, etc. In today's era when companies are undergoing digital transformation and upgrading, what we call data protection may be more focused on For enterprises, in order to ensure business continuity, data reliability, compliance and low packet loss. Therefore, at present, the most favored by enterprises, especially banks, is undoubtedly the off-site disaster recovery and backup solution in two places and three centers. Reduce the risk of over-concentration of core businesses in a single main data center and weaken the interaction between businesses, so that core businesses can be deployed separately. According to the scale and function, the construction can be roughly divided into headquarters-level data centers, provincial/municipal branch data centers, sub-branches and business outlets.

The first step: Dual centers in the same city refers to the establishment of two data centers in the same city or neighboring cities that can independently undertake the operation of key systems. The dual centers have basically the same business processing capabilities and can provide real-time data processing through high-speed links. Synchronizing data can share the operation of business and management systems at the same time in daily situations, and can switch operations; in disaster situations, disaster recovery emergency switching can be performed without basically losing data to maintain continuous business operation.

Step 2: A remote disaster recovery center refers to establishing a backup disaster recovery center in a remote city for data backup in dual centers. When the dual centers fail due to natural disasters or other reasons, The remote disaster recovery center can use backup data for business recovery.

The above enterprise-level data protection includes three sub-solutions: disaster recovery, backup, and archiving, which solve the problems faced by enterprises from the following three perspectives:

Firstly, Business continuity means that in the event of a disaster, the information system can continue to operate normally, helping the company achieve the goal of business continuity;

The second is data recoverability, which prevents the system from operating errors or malfunctions. Data loss;

The third is regulatory compliance. For example, laws and regulations require production data to be kept for more than ten years.

Complete disaster recovery architecture design, appropriate solution implementation, and strict process specification execution are the basis for ensuring business continuity in all walks of life. They are also the needs of society and the requirements of policies and regulations. Disaster recovery, not data.” Server disaster recovery and backup solutions are crucial for enterprises.
