Abstract:

Big data has become the focus of the social attention,it will raise a new competition in science and technology and comprehensive national strength,especially in the disaster recovery and backup data.Therefore,based on the analysis of the current industrial status and the requirements about big data disaster recovery and backup,the advantage and disadvantage of several typical technology solutions were discussed,then a better incremental backup data recovery solution was proposed.This solution can support minute RPO,and meet current requirements about the disaster recovery and backup data.

Key words: big data, backup, recovery, service continuity
