Abstract

The invention discloses equipment, a system and a method for data backup. The method for data backup comprises the steps: by taking a time interval T as a period, computer equipment is used for backing data up on an external storage device by adopting a first backup method; by taking a characteristic tag of the first backup method as an input value, the computer equipment is used for generating a sequence by using a sequence generating algorithm, wherein the sequence is formed by two elements of different states and is M in length; during the period T of the first backup method, by taking a time interval t as a period, the computer equipment is used for backing the data up on the external storage device respectively by adopting a second backup method and/or a third backup method according to the two elements of different states of the sequence, wherein M is greater than or equal to 1 and is an integer; when mod (T, t)=0, M=(T/t)-1; when mod (T, t) is larger than 0, M=[T/t].

Description

technical field [0001] The invention relates to the field of computer data storage and processing, in particular to a computer data backup device, system and method. 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. Data backup is particularly important for enterprises. In the case of data loss caused by equipment failure or irreparable data due to operation errors, the original data can be restored completely, quickly, simply and reliably through the backed up data. [0003] Currently, there are three commonly used data backup methods: [0004] (1) Full backup (FullBackup) [0005] A full backup refers to a complete copy of all data or applications at a certain point in time. Backs up all selected folders and does not rely...
