Problems solved by technology

First of all, in the copying process, the copying of the next file needs to be completed after the copying of the previous file is completed. Therefore, the cold backup speed is slow and the cold backup efficiency is low; secondly, before the cold backup data is backed up in the dis

Embodiment 1

[0039] In this embodiment, the specific implementation process of data cold backup is described in detail by taking the data cold backup of a certain distributed storage system tdb system as an example.

[0040] In this embodiment, the data in the tdb system is cold-backed up to the Hadoop system. The Hadoop system is also a distributed system, which is equivalent to the above-mentioned data cold backup device, which can include HDFS module, mapreduce module and cold backup module. Among them, the HDFS module is equivalent to the above-mentioned distributed storage module, which is used for parallel distribution of files. Fault-tolerant processing and storage, the HDFS module includes a central server (NameNode) and at least one node server (DataNode), Namenode is responsible for managing the namespace (namespace) and client access to files, Datanode is responsible for storing and managing files; mapreduce module , which is equivalent to the above-mentioned split module, is us...

Abstract

The invention discloses a data cold standby method. The method includes the steps of generating a cold standby task including pre-configured cold standby data parameters, dividing the cold standby task into at least one sub task, executing the at least one sub task respectively, acquiring corresponding cold standby data from a cold standby data source, and storing the cold standby data in a distributed mode. The invention further discloses a corresponding data cold standby device. Net data copying, cold standby task centralized processing and cluster management of the cold standby data can be achieved, cold standby speed and efficiency are effectively improved, besides, the cold standby data are stored in the distributed mode, so that storage reasonability of the data, the application rate of a disc and the utilization rate of cold standby resources are improved.

Description

technical field [0001] The invention relates to data processing technology in network communication, in particular to a data cold backup method and device. Background technique [0002] In the field of information technology and data management, backup refers to the duplication of data in the file system or database system; in the event of a disaster or misoperation, the effective data and normal operation of the system can be restored conveniently and in a timely manner. [0003] Backup can include the following types: full backup, that is, to copy all files, folders or data in the hard disk or database at one time; incremental backup, to back up the updated data after the last full backup; selective backup, Backup part of the system; cold backup: backup when the system is shut down or under maintenance. In this case, the backup data is completely consistent with the data in the system at this time; hot backup: backup when the system is in normal operation. In this case, s...
