Example Embodiment

[0050] In the embodiment of the present invention, the backup node creates a snapshot for the backup object through Hbase. When backup is needed, the data in the snapshot is backed up to the remote storage node through HDFS, so that not only does the Export tool need to be used for data export operations, but also Only the incremental part of the data can be backed up, which can greatly shorten the backup window and improve the backup efficiency.

[0051] The embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings of the specification.

[0052] Such as figure 1 Shown is a flowchart of a data backup method provided by Embodiment 1 of the present invention, and includes the following steps:

[0053] S101: The backup node creates a snapshot for the backup object through the distributed data storage system Hbase according to the instruction of the control node;

[0054] S102: The backup node backs up the data in the crea...

Abstract

The invention relates to the technical field of data backup, in particular to a data backup method and device and a data recovery method and device. The data backup method and device and the data recovery method and device are used for solving the problem that needed backup and recovery window are comparatively long in the method of using an Export tool and an Import tool in an Hbase to conduct data backup and data recovery in the prior art. The data backup method comprises the steps that backup nodes create snapshoots for backup objects through the Hbase according to instructions of control nodes; the backup nodes backup the data in the created snapshoots to far-end storage nodes through a Hadoop distributed file system (HDFS). The data recovery method comprises the steps that recovery nodes read data stored in far-end storage nodes according to the instructions of the control nodes; the recovery nodes handle the read data to data in a snapshoot format, and the handled data are written into a data recovery system for providing a data access service through an HDFS interface.

Description

technical field [0001] The invention relates to the technical field of data backup, in particular to a data backup method and device, and a data recovery method and device. Background technique [0002] The billing statement system of the mobile business operation support system (Business and Operation Support System, BOSS) has been established for many years, and it undertakes basic functions such as original call bill approval processing, bill generation, and bill detailed bill query, and provides data for statistical analysis, etc. However, with the increasing number of users and business volume, the massive data of the billing statement system has caused problems such as insufficient storage space, degraded query performance, bottlenecks in statistical analysis, and difficulties in modifying file libraries. Based on these problems, people have introduced The column mode and the distributed database (Hbase) system suitable for storing massive data have brought a comprehen...
