US Patent 10157105 Method for data protection for cloud-based service system

A method for data protection in a cloud-based service system is disclosed. The method includes the steps of: A. collecting historical operating data of storage devices in the cloud-based service system; B. building up a life expectancy model and a next-7-days failure probability model by the collected operating data; C. inputting operating data in the past 24-hours into the life expectancy model and the next-7-days failure probability model for every storage device to obtain ranges of expected lifespans in respective groups and corresponding failure probabilities; and D. backing up data in the storage devices according to the results of step C.
