Cloud Data Backup and Recovery Method Based on the DELTA Compression Algorithm

To keep the original storage proportion of cloud data parameters after an information attack, a cloud data backup and recovery method based on a delta compression algorithm is proposed in this paper. First, improve the key file management strategy in the delta compression framework, and then complete the cloud data processing based on the delta compression algorithm by standardizing the transmission form of data information files. Then, the backup processing technology and recovery application mechanism are studied to realize the smooth application of cloud data backup and recovery methods based on the delta compression algorithm. The experimental results show that under the action of the delta compression algorithm, the storage proportion of cloud data parameters will not decrease infinitely with increasing information attack intensity, which meets the practical application requirements of stably storing data and information files.
