Description
Technical field
The present invention relates to the terminal operating system technical field of data processing, especially a kind of terminal operating system and data in real time remote backup, reduction and clone's method.
Background technology
Backup is a kind of basis of disaster tolerance, is meant to anti-locking system misoperation occurs or the system failure causes loss of data, and the process of the storage medium that all or part of data acquisition is copied to other from the hard disk or the array of applied host machine.Backup can make data avoid unexpected loss.For example, can create the copy of data in the hard disk, then data storage arrived other memory devices.The back-up storage medium both can make logical drive (like hard disk), independent storage devices (like moveable magnetic disc), also can make automatic switch tissue and control whole magnetic disk storehouse or disk band.If the raw data on the hard disk is by accident deletion or cover, or because hard disk failure and can not visit data, so just can from record copy, reduce these data.
Along with the develop rapidly and the wide application of information technology of electronicalization process, data more and more become the foundation of indispensable part and managerial decision in enterprise, the public institution's daily operation.But the use of computing machine also can bring worry to people sometimes, and that is exactly that computer data is very easy to lose and destroyed.Have the data of professional institution to show: the data of losing 300MB just mean 130,000 yuans loss for the marketing department, and treasurer's department is meaned 160,000 loss, and loss can reach 800,000 concerning engineering department.And if the critical data of losing still can not get in 15 days recovering, enterprise just might be eliminated.Along with computer system more and more becomes the indispensable data carrier of enterprise, how utilizing data backup to guarantee data security also becomes the problem that we press for research.
Data are destroyed, and might be artificial factors, also possibly be because various unpredictable factors mainly comprise the following aspects:
(1) Computer Hardware Malfunctions.Computing machine is a machine, and its hardware is the basis of total system.Owing to improper use or reason such as the computer product quality is not good, accessory is aging, the hardware of computing machine possibly be damaged and can not use.For example, the damaged track of hard disk.
(2) instability of computer software.Owing to the reasons such as reliability instability of user's improper use or system, computer software might be paralysed, and can't use.
(3) maloperation.This is artificial accident, can not avoid fully.For example, when using the DELETE key, useful data have been deleted because of carelessness.
(4) destructive virus.Virus is the very important reason that system possibly destroyed.Along with the development of infotech, various viruses are also spread unchecked thereupon.Now, virus not only can be destroyed software systems, also possibly destroy the hardware system of computing machine, and for example the virus CIH of outbreak in every month of current popular 26 days is exactly a typical virus of destroying computer hardware system.
(5) disaster, for example big fire, flood, earthquake etc.This is the almost irresistible reason of a kind of manpower.
Perhaps have the people unimaginable, a slight machine room fire, just possibly make a transnational enterprise infosystem collapse all.The procurement data of the dozens of production center, the whole world, the order of tens thousand of suppliers and retail trader, tens yuan stock information, tens0000 employees the year-round operation plan, all possibly in one minute, just come to naught.Therefore, the data security system of in the past having only the intensive enterprise of financial datas such as bank and telecom dealer just to use just more and more becomes the preventive measure that all kinds of enterprises have to provide for a rainy day and take.Morgan Stanley wakes up from death, just a living example.
And original backup, reduction technique ubiquity: terminal concurrence linking number less-restrictive (being generally 20 ~ 30), can only the backup operation system maybe can only carry out static backup to file, need interrupt work at present or the like problem when the backup file data.Everything has all determined necessity and urgency that real-time, dynamic, long-range, intelligentized operating system and data backup, recovery and clone's new technology occurs.
