Problems solved by technology

However, when different terminals log in to the same cloud backup account for backup, the cloud server needs to fully back up the data of each terminal, which will lead to low efficiency of data backup
[0004] For example, taking the backup of contacts as an example, after Terminal A, Terminal B, and Terminal C log into the same cloud back

Embodiment 1

[0034] This embodiment will be described from the perspective of a data backup device, and the data backup device may specifically be integrated into a server.

[0035] A data backup method, comprising: receiving first data to be backed up and a target backup account sent by a master device, and backing up the first data to be backed up to a first storage area corresponding to the master device under the target backup account, and then, Receive the second data to be backed up and the target backup account sent by the slave device, obtain the difference data between the second data to be backed up and the first data to be backed up, and back up the difference data to the target backup account and the slave The second storage area corresponding to the device.

[0036] like figure 2 As shown, a data backup method, the specific process is as follows:

[0037] 101. Receive first data to be backed up and a target backup account sent by a master device, and back up the first data ...

Embodiment 2

[0089] This embodiment will be further described on the basis of the method provided in Embodiment 1.

[0090] This embodiment is described in detail by taking the data backup device of Embodiment 1 integrated in a server as an example. The server can be a cloud server for backup.

[0091] refer to image 3 , a data backup method, the specific process is as follows:

[0092] 201. The master device sends a first data backup request to a server, where the first data backup request carries first data to be backed up, a device identifier of the master device, and a target backup account.

[0093] Specifically, the main device may receive the backup instruction, and send the first data backup request carrying the first data to be backed up and the target backup account to the server according to the backup instruction.

[0094]Wherein, the backup instruction can be triggered by a certain event, for example, it can be automatically triggered by a data change. Specifically, when a...

Embodiment 3

[0123] In order to better implement the above method, the embodiment of the present invention also provides a data backup device 30, such as Figure 4 As shown, the data backup device 30 includes a first backup unit 301, a receiving unit 302, a difference acquisition unit 303 and a second backup unit 304, as follows:

[0124] The first backup unit 301 is configured to receive the first data to be backed up and the target backup account sent by the master device, and back up the first data to be backed up to the first storage area corresponding to the master device under the target backup account;

[0125] a receiving unit 302, configured to receive the second data to be backed up and the target backup account number sent by the slave device;

[0126] a difference obtaining unit 303, configured to obtain difference data between the second data to be backed up and the first data to be backed up;

[0127] The second backup unit 304 is configured to back up the difference data to...

Abstract

The embodiment of the invention discloses a data backup method, device and system. The data backup method disclosed by the embodiment comprises the following steps: receiving first data to be backed up and a target backup account, which are sent by master equipment; backing the first data to be backed up to a first storage region, corresponding to the master equipment, in the target backup account; then, receiving second data to be backed up, sent by slave equipment, and the target backup account; obtaining the distinguishing data between the second data to be backed up and the first data to be backed up; and backing up the distinguishing data to a second storage region, corresponding to the slave equipment, in the target backup account. By adopting the data backup method, device and system, the efficiency of backing up the data can be improved.

Description

technical field [0001] The present invention relates to the technical field of cloud backup, in particular to a data backup method, device and system. Background technique [0002] Cloud backup is an emerging cloud computing business. Cloud backup service providers use technologies such as virtualization, distributed processing, and broadband networks to gather massive and heterogeneous storage devices in the network to work together and provide data storage backup to the outside world. Serve. Users can access through mobile Internet and broadband Internet to realize centralized storage and safe keeping of a large number of scattered files or folders on the terminal. [0003] Among them, the cloud backup is to back up the data in a certain terminal to a cloud server. In the existing cloud backup solution, multiple terminals can log in to the same cloud backup account and cloud server for data backup. However, when different terminals log in to the same cloud backup accoun...
