Storage device configuration information continuous optimization backup system and application method thereof

Abstract

The invention provides a storage device configuration information continuous optimization backup system. The continuous optimization backup system can back up the storage device configuration information in the premise of greatly reducing the backup data occupied space, recover and roll back the storage device configuration information according to the backup data. The system comprises a basic data zone for storing original configuration information of the storage device, and further comprises a configuration backup zone, wherein the configuration backup zone is provided with a plurality of backup blocks; each backup block comprises a head description zone and a data zone; the head description zone stores timestamp and data zone length of the current backup point; the data zone stores the backup data corresponding to the head description zone; the backup data stored in the data zone is obtained by performing OR operation and compression to the storage device configuration information of the point in time corresponding to the backup block and the storage device configuration information corresponding to the adjacent last point in time. The invention further provides an application method of the system.

Description

technical field [0001] The invention relates to the field of computer information storage, and relates to a storage device configuration information optimization backup system. The invention also provides a method for using the system. Background technique [0002] With the continuous development of storage and network technologies, the capacity of network storage has increased exponentially. Enterprise-level storage devices are becoming more and more powerful and rich in functions, and their configurations are becoming more and more complex. While the system administrator hopes to simplify the management of storage devices, he also requires the security and stability of configuration information, because the configuration information of storage devices Correctness is the basis for data storage security and stability. Therefore, stable and reliable storage of storage device configuration information and recovery capabilities under abnormal conditions are particularly importa...

AI Technical Summary

Problems solved by technology

[0004] In traditional enterprise-level storage devices, configuration information is generally stored in a format set by the manufacturer through files or directly written to storage media. This method cannot record the chronological order of configuration operations, nor can it conveniently operation rollback

[0005] The method of backing up all the data in the configuration information management area in chronological order after each modification of the configuration information can realize continuous protection of the configuration information data, but because the configuration information management area reserved by enterprise-level storage devices generally has a large space, Between several megabytes and even hundreds of megabytes

If this method is used for continuous protection, it will greatly waste space, and the backup data itself will have an impact on the performance of the storage system
