We lived in a world of data. Data can be created and used continuously across an organization[1]. For us, how to ensure the availability of data and protecting it from out of use is the challenge we need to face. Recently,Continuous Data Protection is used for data recovery,but the disadvantage of it is it allways requires a lot of storage space. To resolve it,We present Warm-CDP system,it is a new method to do data recovery and protectionin, it aims at less data storage needed and lower overhead to do a recovery when primary node is down, and the performance evaluation is described in the end.
