Data backup method and system and server

Abstract

The invention discloses a data backup method, a data backup system and a server, and the method comprises the steps that the server receives the setting of a backup mode, a backup type and a backup trigger condition by a user, generates a data backup strategy and issues the data backup strategy to one or more clients; When the one or more clients meet the backup trigger condition, a data file is transmitted to a server; And the server performs backup on the data file according to the backup type and generates a backup record at the same time. Different backup strategies can be configured for clients of different users, the backup strategies are flexible and adjustable, and various data backup requirements can be met.

Description

technical field

[0001] The invention belongs to the technical field of data disaster recovery, and in particular relates to a data backup method, system and server. Background technique

[0002] Data backup is the basis of disaster recovery, which refers to the process of copying all or part of the data set from the hard disk or array of the application host to other storage media in order to prevent data loss caused by system operation errors or system failures. Inter-system data backup is a common data backup method, that is, data is backed up to another storage system. In the traditional inter-system data backup, users regularly copy the data that needs to be backed up on the main system to another system. This backup method lacks real-time and high efficiency.

[0003] Moreover, for units with a high level of confidentiality, data security and confidentiality requirements are very high, such as the data of the surveying and mapping department, and the medicinal material...
