Problems solved by technology

In traditional data backup storage, the backup data is directly written to the storage layer without compression. The storage process takes a long time and takes up a lot of storage space. Especially, the cost of saving on flash media is high, which increases the operation and maintenance cost of the enterprise. Data compression is performed by calling the gzip library by the CPU, which consumes additional CPU and puts forward higher requirements on CPU performance.

Abstract

The invention relates to a data backup and recovery device and method based on a special compression card, which belongs to the field of information technology and solves the problems of data backup storage efficiency and storage cost. The invention compresses / decompresses the data to be backed up / restored by integrating a special compression card Compression, storage to the storage layer / restoration to the database, realizes data backup / restore of the database. The present invention uses a dedicated compression card to improve space storage efficiency and save storage costs, especially the storage costs of high-performance media such as flash memory, without affecting the CPU and storage performance; and the compression process works on the storage layer, for the upper database Business access is completely transparent.

Description

technical field [0001] The invention relates to the field of information technology, in particular to a data backup and recovery device and method based on a special compression card. Background technique [0002] With the development of enterprise informatization, business functions, the number of users, and the number of units are increasing year by year, and the amount of informatization data is increasing rapidly. The backup storage of database data files and archived logs is the focus of database operation and maintenance. In traditional data backup storage, the backup data is directly written to the storage layer without compression. The storage process takes a long time and takes up a lot of storage space. Especially, the cost of saving on flash media is high, which increases the operation and maintenance cost of the enterprise. Data compression is performed by calling the gzip library by the CPU, which consumes additional CPU and puts higher requirements on the perfo...
