Abstract

The invention relates to a method and a device for data recovery treatment and a computer storage medium. The method comprises the following steps of determining whether a data block is updated or not; according to the occurrence of updating of the data block, performing data recovery treatment. The method provided by the embodiment has the advantage that the data recovery treatment is performed according to the occurrence of updating of the data block, so that the redundancy in data recovery treatment is decreased, and the efficiency of data recovery treatment is improved.

Description

technical field [0001] This article involves but is not limited to data processing technology, especially a method, device and computer storage medium for data recovery processing. Background technique [0002] While the amount of user data is increasing day by day, the importance of data is also gradually increasing; for the user's critical applications, any amount of data loss may cause huge losses. Continuous data protection (CDP, continual data protection) technology is a method of continuously capturing and saving data changes, and saving the changed data independently of the initial data, and this method can realize data recovery at any point in the past; CDP Technologies may be block, file or application based and provide granular recoverable objects for an unlimited number of variable recovery points. The block-level CDP technology is independent of upper-layer applications, and because it directly operates data blocks, its data backup and recovery efficiency is hig...
