Variable-Length Data Block Based Disaster Data Recovery Algorithm
Yan Yi-xian · Journal of Chengdu University of Information Technology · 2010
Extreme characteristics of the fingerprint-based byte of data distribution algorithm,present a recovery algorithm of disaster data.Through the data block and the value of comparative digest between source and backup,using differential copy method to copy to complete data recovery.In all,this recover method detects duplicate data effectively,so it can save a large amount of network bandwidth.
