Abstract

The present application provides a data backup method and device, the method comprising: backing up short-term data stored in a relational database in a data warehouse, and pushing the log of the relational database to a Hadoop storage cluster for backup; The condition is to filter out the long-term data from the data backed up by the data warehouse; push the long-term data from the data warehouse to the Hadoop storage cluster for storage. The loss of long-term data is avoided, and the long-term data and logs can be used to restore the long-term data to any point in time.

Description

technical field [0001] The present application relates to Internet technology, in particular to a data backup method and device. Background technique [0002] Hadoop is a software framework capable of distributed processing of massive data, allowing users to easily construct and use a distributed computing platform. Users can easily develop and run applications that process massive amounts of data on Hadoop. And it can quickly expand from one server to a cluster of tens of thousands of servers, while providing higher high availability and fault tolerance at the software architecture level. [0003] Hadoop Distributed File System (Hadoop Distributed File System, HDFS) is designed as a distributed file system suitable for running on general-purpose hardware. HDFS is highly fault-tolerant and designed to be deployed on low-cost hardware. And it provides high throughput to access application data, suitable for applications with very large data sets. HDFS can implement stream...
