Abstract

The embodiment of the invention discloses a method and equipment for data backup, and a distributed cluster file system, wherein the method comprises the steps of scanning the file range in the charge of a node in a backup transfer table by a background backup thread of each node in a first cluster; for a scanned written-in file, writing the written-in file into a second cluster by the background backup thread of the node in the first cluster. The files can be automatically backed up into other clusters by the embodiment of the invention, and the safety of the backup files is improved.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a data backup method, device and distributed cluster file system. Background technique [0002] Cassandra is a hybrid non-relational database. The main feature of Cassandra is that it is not a database, but a distributed network service composed of a bunch of database nodes. A write operation to Cassandra will be copied to other nodes. Going up, the read operation on Cassandra will also be routed to a node for reading. For a Cassandra cluster, scaling performance is relatively simple, just add nodes to the cluster. [0003] However, compared with traditional databases such as the existing MYSQL (relational database management system), the Cassandra cluster lacks an automatic database backup mechanism. There is no backup solution for the entire Cassandra cluster data. Completely backing up data in one cluster to another cluster will obviously greatly improve data security and...
