Abstract

The invention discloses a data cloud backing-up method and system. The method comprises the steps of after a first instruction is received, when data of data blocks in a to-be-backed-up volume is rewritten, replicating data before rewriting in the data blocks, and recording the distribution and status of each data block in the current to-be-backed-up volume at the same time; comparing the distribution and status of each data block in the currently recorded to-be-backed-up volume with a result recorded when the data of the to-be-backed-up volume is rewritten last time, and uploading the data before rewriting of the data blocks the states of which are changed to a cloud server for storage. According to the data cloud backing-up method and system, when the data of the data blocks in the to-be-backed-up volume is rewritten, the data in the data blocks is replicated and uploaded to the cloud server for backup; when all the data blocks in a backup volume are rewritten, all data in the volume is backed up. Compared with the prior art, by means of the method and system, the situation is avoided that a large amount data is replicated and uploaded in one time, the bandwidth occupation can be reduced, the replication rate is increased, and the time consumption is reduced.

Description

technical field [0001] The invention relates to the technical field of data backup, in particular to a data cloud backup method and system. Background technique [0002] In the prior art, the method for data cloud backup is to upload all the volume data to be backed up in the storage system to the cloud at one time by copying. If this method encounters a large amount of data to be backed up, copying A lot of data puts a lot of pressure on bandwidth and is very time-consuming. Contents of the invention [0003] The purpose of the present invention is to provide a data cloud backup method and system, which can reduce the bandwidth occupation, speed up the copying rate and reduce time-consuming compared with the prior art. [0004] To achieve the above object, the present invention provides the following technical solutions: [0005] A data cloud backup method, comprising: [0006] After receiving the first instruction, when the data of the data block in the volume to be b...
