A method and device for data backup management

Abstract

The purpose of this application is to provide a method and device for data backup management; obtain the first data block that has been changed in the target disk of the corresponding data providing device, wherein the first data block is stored in the format of the first compressed data package form for data transmission; based on the first compressed data packet, allocate a corresponding first storage space for the first data block; based on the storage location information corresponding to the first storage space, generate the first data block First snapshot information, wherein the first snapshot information includes corresponding creation time information. Compared with the prior art, this application realizes the remote, centralized, and real-time backup of the disk data in the corresponding several data provision devices by the data management device, among which, the real-time changed data blocks can be backed up in real time, reducing the risk of backup data loss ; In addition, through the form of the first compressed data packet, the amount of data actually transmitted can be effectively reduced.

Description

technical field [0001] The present application relates to the computer field, in particular to a technology for data backup management. Background technique [0002] With the expansion of computer network applications, such as cloud computing, e-commerce, social networking and other applications, the amount of data information that needs to be stored has increased rapidly. In the process of data use, data may be lost due to unexpected reasons, such as the destruction of the storage medium, or human misoperation; Data backup storage achieves the above-mentioned purpose. [0003] However, in the prior art, most of the data backup management systems are performed locally, and if the local equipment fails, the backup data will be lost at any time, and the security of the backup data cannot be guaranteed. At the same time, the data of multiple devices in the system needs to be backed up. Managing the backup data of each device separately will increase the maintenance workload a...

Problems solved by technology

In the process of data use, data may be lost due to unexpected reasons, such as the destruction of the storage medium, or human misoperation; Data backup storage achieves the above purpose

[0003] However, in the existing technology, most of the data backup management systems are carried out locally, and if the local equipment fails, the backup data will be lost at any time, and the security of the backup data cannot be guaranteed.

At the same time, there are multiple devices in the system that need to be backed up. Managing the backup data of each device separately will increase the maintenance workload and is not conducive to resource utilization.

[0004] In addition, in the prior art, there is also a backup method that periodically creates data snapshots in each device to be backed up, and then periodically saves the snapshots in the corresponding backup server, but regular backup of snapshots cannot achieve real-time data update , there is a risk of data loss, such as the possible loss of at most two adjacent backup time points, that is, possible update data within a backup cycle, resulting in large data backup errors

At the same time, creating a snapshot in the device to be backed up will affect the normal operation of the device

[0005] In addition, in the existing technology, if the amount of backup data transmission between devices in different places is large, the transmission efficiency will be low due to the uncompressed or ineffective compression of the transmitted data, which will affect the efficiency of data backup
