Building Effective Data Disaster Recovery Is Significant On The Hospital Information System

Rapid development of medical information technology

, medical information, as coverage and greater amount of data, and a wide range of information, but also to maintain updated 24 hours a day. Once a large amount of data makes the data corruption or loss, will result in incalculable damage to the hospital, so building effective data disaster recovery is essential for the hospital information system.

Disaster Recovery is not a simple

But a long time and most of the hospitals do not build an effective disaster recovery mechanism, as long as the database problems, there is no way, will inevitably lead to very serious consequences. Some hospitals also use the appropriate backup systems, but only achieved by copying the backup data is no guarantee that the data from security and business continuity operations. When the server is actually DOWN out of time, not only to restore a backup neutral gear of the data, business interruption will affect the operation of the hospital.

In fact, the disaster is not just a backup that simple! It means that when a disaster occurs, IT systems can in the shortest time to resume operations with minimal loss of running. From traditional data backup disaster recovery techniques, the main domestic regular cold backups, snapshot backups, dual-plane clustering, Raid some, but not enough to meet such technical data of hospital information system requirements of security and business continuity .

Expensive quasi-continuity disaster recovery Example, a hospital in order to solve the hospital information security business continuity and data using a dual-machine cluster model to support the application of hospital HIS system. The program uses two different server configurations, using shared storage disk cabinet. By installing the cluster Management Software Can be achieved: at the same time only one server and disk counters for the client to provide services and data. When the machine is down, the other one sleep machine will wake up, continue and disk counters for the client to provide services and data. That may seem like a perfect program, set the cumbersome, expensive, continuity is very strong, and the disk cabinet also made a raid, not afraid of the damage a single disk.

Figure 1 But when we analyze in detail the time but found a lot of fatal problem. First look at raid, damage to a single disk, the other disk after the data is deleted. This case, if the incident occurred accidentally deleted, then the data is brought back, or even the cost of looking back is also very large.

Next we look at two planes: two planes to use as a shared disk cabinet, so only the local two-machine, the local two-machine is not available disaster recovery capability, if for some unexpected disaster, such as fire, flood Dual lead to physical damage, then the data was no more.

Once again look at cost: because the two computers server1 and server2 the configuration requirements must be exactly the same, and the need to counter the secondary disk, which invisibly increase in hardware costs. So expensive, "thorough" option does not solve the health care industry, the data may be a crisis, it has become a health care information technology industry, an urgent need to solve important problems. Until the CDP (continuous data protection) technology appears, disaster recovery can truly entered a new stage to ensure business continuity.

And of the mind "being prepared"

As technology continues to develop and research information on the characteristics of the medical industry, in-depth understanding of Beijing and of the mind and Technology Co., Ltd. launched the "be prepared for" data backup products?? UPM database bodyguards, the perfect solution to the defects as those mentioned above.

Figure 2 UPM database bodyguards achieve real-time hot backup of database program basically made up of two two-plane defects. Not only allow the hospital retrieve accidentally deleted data, but also through the network backup, remote backup and disaster recovery server, greatly improved data security. It is worth mentioning is the backup server, this program can be fully and inconsistent HIS server, including operating systems and hardware. This means you can use low-end configuration backup machine to reduce backup costs. Four features of the three backup

To be effective, low-cost health care industry, information technology security, Beijing and of the mind and Technology Co., Ltd. "be prepared for" data backup products?? UPM database bodyguard has the following important features. First of all, UPM can automatically monitor the database, continuous backup of data capture and change the data as long as the database changes, then real-time, accurate back down; Secondly, UPM can be any action steps or time data fast recovery, Back to the database, any state, to be able to recover accidentally deleted, or damaged before the data. In the recovery process not only ensures the integrity of the data type, but also ensure the integrity of the event; third, UPM in the main database server is down after the backup machine from the database to take over the main points of the IP and the external database services; Finally, UPM can be adopted in different places on the WAN and LAN data on the machine with the database backup. Applicable to all kinds of disaster recovery needs of different sizes of enterprises.

UPM also offers three other cost advantages of different backup: restore data types, user specified in the backup directory backup database files, data loss when the main station, the station master and slave can be applied to the data recovery module data load back to the main station. Loading process can be steps or time rewind data to adjust the integrity of the database. This backup hardware costs are the lowest on the PC configuration is basically no requirements.

The second is to avoid a backup to restore the data type, which means the software will be loaded into the data files directly from the station (back-up) in the database, when the main station (work machine) can immediately take over the work after paralysis. Backup does not require recovery, but no rollback feature. Backup data in this way occupy less disk space, can take over the IP, and database services. It demands a relatively high profile, and from the station to install the same version of the master database, no data rollback feature. Double backup

third type is the addition to the backup directory specified by the user in the form of a backup database file files, while also loaded into the database files directly from the station (back-up) in the database. This can prevent recovery from the station, you can also rollback. Are clear advantages to it that can be taken over IP and database services, data can be reverted. But equally, the backup
