Method and device for carrying out safety backup on memory data

Abstract

The invention provides a method for carrying out the safety backup on memory data, comprising the following steps of: acquiring the memory data of an initiated application program as well as basic information and auxiliary information of the memory data; caching the acquired memory data of the application program as well as the basic information and the auxiliary information of the memory data into a cache unit; judging whether the basic information and the auxiliary information of the memory data cached by the cache unit are both not changed or not, and if yes, not carrying out the backup on the cached memory data; if not, further judging whether the backed-up memory data contains data which is same as the basic information and the auxiliary information of the memory data or not, if yes, not carrying out the backup on the cached memory data, and if not, carrying out the backup on the memory data cached in the caching unit. The invention also provides a device for carrying out the safety backup on the memory data. By adopting the method and the device, the invention can carry out the safety backup on the memory data which is not stored into a disk on the premise of not influencing the normal operation of a system.

Description

technical field [0001] The invention relates to data backup technology, in particular to a method and device for safely backing up memory data. Background technique [0002] Data backup and recovery has become a data protection measure commonly used by enterprises and institutions. After the data stored on the disk of the data source is backed up to the backup system through the backup method, when various errors occur in the data source and the data is lost, The data in the backup system can be restored to the data source for continued use by the data source. [0003] The current data backup and recovery methods can only protect the data stored in the disk, and there is no way to protect the data that has not been stored in the disk in the memory, which will cause the data that needs to be saved in the memory to be easily lost. losses to users. For example: when the user does not actively save the edited data, the data edited by the user has been saved in the memory but h...

AI Technical Summary

Problems solved by technology

After the server or client starts, the application runs in protected mode, which makes it impossible to directly access the memory data of the application; and mandatory access to the memory data of the application often affects the stable operation of the application

Therefore, due to the limitation of the working mode of the server or client, it is difficult to realize the safe backup of the memory data
