In recent years,the role of information technology in the development of the society has become more and more important,whether it is in the field of military information confrontation,the basic daily business or financial enterprises,are needed for effective storage of data.With the increase of data quantity,people put forward higher request to the reliability of data storage.Currently the market uses redundant technology through the disk array to get data security and reliability are effectively improved.Disk array is a practical and reliable data storage device,and its application is more and more wide.Modern social data update speed has been faster and faster,the demand for the size of the disk array storage capacity is also increasing.Data storage in the disk array has a variety of forms,the general multi block storage form,that is,data stored in the form of data blocks on the disk array,and cross disk storage.This results in a single disk drifting,unable to identify data in the disk,causing disk unavailability.In this paper,an improved disk array architecture is proposed,which builds a virtual logical disk array based on the underlying disk.Combined with the mixed storage of data block and file,this paper aims to effectively improve the data recovery rate of fault disk,and proposes a backup scheme to solve the data security in cloud storage.First,we propose a multiple storage backup scheme based on cloud storage environment.This program takes full account of the characteristics of the security industry,and fully consider the redundancy and other characteristics,puts forward a kind of safe and reliable,low redundancy of the multi replica management strategy,the establishment of multi copy storage node,although this scheme still exists redundant,but the data reliability was greatly increased.Then,a new logical disk array based on IPSAN technology is established.The data storage using a multi-level index storage structure of Dev data,using the file with data block storage,Dev design a logical volume no longer across disk storage,compared to the original disk array across disk logical volume data of Dev drift structure has better(mobility)and recognition rate.At the same time,the disk data is recovered and verified by parity calculation.Finally,the drift scheme of the completed disk array is analyzed,and the related experiments are carried out to verify its function and basic performance characteristics.Disk array architecture is proposed in this paper.The experiments show that it has better disk drift characteristics,identification of single disk array in the drift data rate is high,with high reliability,and multi copy backup strategy has good application value,strong stability,has important economic significance on video cloud storage security enterprise.
