Technology for continuous data protection based on CDP

Abstract

A technology for continuous data protection based on CDP refers to that data is monitored automatically continuously without a stop; data changes are captured and backed-up continuously; the data can be recovered quickly according to arbitrary operation steps or time points; the data of a structuralized database type can be recovered to any state of the database; and non-structuralized data can be recovered to a designated time point. Hence, the data which is deleted by mistakes or the data before damage can be found. During recovery, data integrity is ensured, and event integrity can be ensured.

Description

technical field [0001] The invention relates to a CDP-based continuous data protection technology, which belongs to the field of computer disaster recovery and backup. Background technique [0002] At the beginning of the new century, human beings are entering the era of knowledge economy with information technology as the core. Information resources have become as important as materials and energy as strategic resources. All countries in the world regard accelerating the construction of information technology as their national development strategy. With the continuous advancement of information construction and the continuous expansion of business systems, the amount of data generated by business information systems is increasing day by day, and its importance is gradually increasing. For some key applications of users, any amount of data loss may cause huge losses. loss. [0003] Risk of business system data loss: [0004] Logical errors: The probability of occurrence is...

Problems solved by technology

[0011] 1. The CDP implemented based on the application system is only for the protected application system, which occupies a large amount of application system resources

[0012] 2. The CDP based on the file system monitors the data changes on the file system level, and starts to copy after writing the FAT table. At the same time, it needs to read the data first, which consumes a lot of system resources and increases the consumption of network bandwidth.

[0014] For the user to encrypt the partition under the operating system, Zhongke Tongxiang can use the CDP disk image to completely copy all the partition data including the status. When the backup data needs to be accessed, there is no need for too many adjustments, which is also based on the data block The unique advantages of level CDP, the protection based on files and application logs cannot be realized
