Distributed storage scheme based on check-encoded backup
Chen Dongxiao, Wang Peng
Traditional cloud computing storage system, which is used to guarantee usability, usually uses mirrored redundant backup to produce a large amount of redundant data, which affects the efficiency of storage data space utilization. In this case, a storage scheme is proposed to reduce the footprint of backup data for storage space. The image redundancy is discarded, the method of verifying encoding is used to reduce the backup data, the backup is validated by the conflict jump mechanism, and the backup quantity is reduced under the premise of guaranteeing the validity of the backup data. The comparison between the simulation program running results and the mainstream cloud storage scheme shows that the proposed storage scheme can significantly reduce the consumption of the distributed storage to the disk space while guaranteeing the reliability of the data.
