Abstract

The invention discloses a data backup disaster tolerance method. The method comprises the following steps of receiving a control instruction of backup data; on the basis of the control instruction, selecting a backup mode, carrying out segmentation processing on data to be backed up, and obtaining a plurality of data blocks; respectively obtaining first mark information in the data blocks and searching whether the same first mark information exists in the backed-up data or not; when a searching result shows that the same first mark information does not exist; storing the data to be backed up in a local storage terminal, and storing the data to be backed up in the cloud storage terminal through the local storage terminal. Therefore, the technical effects that the transmission data volume can be effectively controlled, and the waiting time is reduced are achieved.

Description

technical field [0001] The invention relates to the technical field of storage device security, in particular to a data backup disaster recovery method. Background technique [0002] With the continuous development of information technology, more and more attention is paid to the security of data. People need to backup disaster recovery protection for data so that they can be restored in time when data is damaged. Existing data backup requires specific equipment, which has a poor effect on data protection and relatively high cost. Cloud storage appeared in the later period. The biggest feature of cloud storage is that it can reduce costs for users. However, in actual application, due to network and other reasons, when storing data, there are technical problems such as large amount of transmitted data and long waiting time. Contents of the invention [0003] The embodiment of the present invention provides a data backup and disaster recovery method, which solves the techni...
