Embodiment Construction

[0035] The technical solutions of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0036] The embodiment of the present invention provides a disaster recovery backup method, the method flow chart is as follows figure 1 shown, including the following steps:

[0037] Step 101, the first storage unit receives a backup instruction input by a user;

[0038] Specifically, the first storage unit may be understood as a client with processing capability and storage capability, including a processing module and a storage module. Wherein, the processing module can be understood as a module for performing disaster recovery and backup calculation processing. The storage module stores data to be backed up that the user needs to perform disaster recovery backup, and it can be a fiber optic disk or other storage media.

[0039] The processing module of the first storage unit receives the backup instruction input ...

Abstract

The invention relates to a disaster recovery backup method. The method includes the steps that a first storage unit receives a backup instruction input by a user, analyzes the backup instruction to obtain data to be backed up and a backup time; when system time reaches the backup time, the data to be backed up and a backup frequency parameter corresponding to the backup time are determined; a first copy instruction is generated and sent to a second storage unit; the second storage unit acquires the data to be backed up from the first storage unit according to address information of the data tobe backed up, and the data to be bucked up is stored locally in the second storage unit as backed up data; a second copy instruction is generated and then sent to a third storage unit when the backedup data matches with the data to be backed up; the third storage unit copies the backed up data from the second storage unit according to the second copying instruction; when the backup frequency parameter is a first backup frequency parameter, local data is obtained; the data to be backed up and the local data are compared according to a data identifier, updated data of the local data is obtained, and the local data is updated according to the updated data.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a disaster recovery and backup method. Background technique [0002] Undoubtedly, data has long been the basis for the survival and development of an information society. While data continues to grow explosively, the field of disaster recovery and backup, which serves as a data and business protection barrier, is also showing multiple development trends. With the acceleration of the informatization process, information security has become the most concerned issue for enterprises and institutions whose business is based on IT systems. All units have higher and higher requirements for data security and business continuity. Data backup, or local disaster recovery cannot meet the demand to some extent. Remote disaster recovery has become the first choice for disaster recovery in more industries. In terms of preventing data loss and business interruption caused by large-scal...
