Abstract

A method and apparatus for redundant storage of data is disclosed. The invention relates to the field of computer data processing. The method comprises the following steps: acquiring data to be processed; Determining a file heat value of the data to be processed; Determining a heat level of the data to be processed according to the file heat value and a predetermined heat threshold; And determining a data redundancy policy of the data to be processed according to the heat level. The method and device for data redundancy storage disclosed in the present application can solve the problem of nodeload imbalance caused by high visiting quantity, and can also solve the problem of wasting storage space caused by less visiting quantity data.

Description

technical field [0001] The present invention relates to the field of computer information processing, in particular to a method and device for data redundancy storage. Background technique [0002] There are a large amount of data such as statements of accounts and transaction records in the financial system. In order to ensure data reliability, a copy redundancy strategy is usually adopted. In the event of data loss or corruption, the backup copy can be used for data recovery. The current common method is to use full copy redundancy to ensure data reliability. Complete copy redundancy is to copy multiple copies of data and store them on different data nodes of the distributed storage system to improve data availability and parallel data processing efficiency. HDFS, the Hadoop distributed file system component, adopts the full copy strategy. HDFS adopts three-copy backup disaster recovery by default. Data is stored through the rack-aware strategy, which is stored in the l...
