Abstract

The various types of embodiment of the disclosure provide an appliance of backing up data. The appliance includes an auxiliary backup appliance that is coupled to a primary backup appliance. The auxiliary backup appliance further comprises: a data segmentation device, which is operable to divide the to-be-backed-up target data into a plurality of data segments; and an abstract data generating device, which is operable to generate corresponding abstract data of each data segment for the plurality of data segments, and provide the abstract data to the primary backup appliance for using for backing up the target data in the primary backup appliance, wherein the abstract data is mapped data segments of which the length are less than the length of the corresponding data segments.

Description

technical field [0001] Various embodiments of the present disclosure generally relate to the field of storage, and more particularly relate to methods and devices for data backup. Background technique [0002] In the field of a purpose built backup appliance (PBBA), de-duplication (de-duplication) technology is one of the most critical technologies. Deduplication operation is a kind of data compression operation, and its purpose is to delete duplicate data and only back up new data before backing up the data to the backup device, thereby effectively reducing the occupation of storage space by duplicate data. Deduplication is a computationally intensive process, including data segmentation algorithms, data summary calculation algorithms, summary index search, etc. In addition, backup appliances often provide data compression and data encryption options, depending on user needs. This can be achieved through a high-performance central processing unit (CPU). However, such CPU...
