Abstract

The invention belongs to the technical field of financial system data backup, and discloses a data backup method based on distributed storage. The method comprises the step of judging the low-peak period of the application server service, confirming a file system where the backup data is located, a file catalogue and a file naming format; judging whether the rest space of the file system where thebackup data is located exceeds a threshold value, acquiring the backup data, generating a storage prefix of the backup data, retransmitting the backup data, performing the distributed storage, deleting a local temporary backup file, and deleting overdue data. Through the scheme, a financial enterprise does not need to purchase additional special hardware equipment, the backup data cost of the enterprise is reduced, the backup data has a plurality of copies in distributed storage, and according to the number of the copies, any server which does not exceed the number of the copies is damaged, the backup data can be recovered.

Description

technical field [0001] The invention belongs to the technical field of financial system data backup, in particular to a method for data backup based on distributed storage. Background technique [0002] Explanation of related terms: [0003] File system: The file system is the method and data structure used by the operating system to specify files on storage devices (commonly disks, and also NAND Flash-based solid-state drives) or partitions; that is, the method of organizing files on storage devices. [0004] Distributed storage: Distributed storage is a data storage technology that uses the disk space on each machine in the enterprise through the network, and forms these scattered storage resources into a virtual storage device, and the data is distributed and stored in various parts of the enterprise. corner. [0005] Data backup: Data backup is the basis of disaster recovery. It refers to the process of copying all or part of the data set from the hard disk or array of...
