With the advent of the era of big data,massive data will be generated every day.If these data are not archived,there will be problems such as information loss and waste of resources.Therefore,in order to ensure the normal operation of the information management system in the era of big data,it is necessary to archive massive data.When archiving big data,it is first necessary to classify it,and then propose corresponding processing methods for different types of data.This paper studies the data archiving system based on big data for reference.
