Problems solved by technology

[0006] During incremental data copying, a snapshot needs to be generated, which is cumbersome to operate; and, during the incremental data copying process, if the server receives a new request for data to be written, the server reads the incremental data in the first storage medium, And write the incremental data to a new storage medium, read the incremental data from the new storage medium, the copy process is complicated

Embodiment 1

[0051] The embodiment of the present invention provides a method for incremental data copy. see figure 1 , where the method includes:

[0052] 101: The server receives a write data request, and the write data request carries the data to be written and the offset address of the data to be written;

[0053] 102: The server binds the data to be written with the cycle identifier of the current cycle, and stores the data to be written in the first storage medium according to the offset address of the data to be written;

[0054] 103: The server obtains the data received in the current cycle according to the cycle identifier of the current cycle;

[0055] 104: The server stores the data received in the current period in the second storage medium.

[0056] In the embodiment of the present invention, when the server receives a data write request, it binds the data to be written with the cycle identifier of the current cycle; when copying incremental data, the server only obtains the ...

Embodiment 2

[0058] The embodiment of the present invention provides a method for incremental data copy. see figure 2 , where the method includes:

[0059] 201: The server receives a write data request, and the write data request carries the data to be written and the offset address of the data to be written;

[0060] Wherein, the data to be written is any data to be written into the storage medium; the offset address refers to the offset of the address of the data to be written relative to the segment head address.

[0061] Wherein, when the terminal wants to write the data to be written into the storage medium, it sends a data write request to the server, and the data write request carries the data to be written and the offset address of the data to be written.

[0062] Wherein, it should be noted that the write data request carries at least the data to be written and the offset address of the data to be written, and the write data request may also carry the identifier of the first st...

Embodiment 3

[0102] An embodiment of the present invention provides a device for incremental data copying. see image 3 , where the device includes:

[0103] The receiving module 301 is configured to receive a write data request, the write data request carries data to be written and an offset address of the data to be written;

[0104] A binding module 302, configured to bind the data to be written and the period identifier of the current period;

[0105] The first storage module 303 is configured to store the data to be written in the first storage medium according to the offset address of the data to be written;

[0106]An acquisition module 304, configured to acquire data received in the current period according to the period identifier of the current period;

[0107] The second storage module 305 is configured to store the data received in the current period in the second storage medium.

[0108] Further, the binding module 302 includes:

[0109] The first acquiring unit 3021 is c...

Abstract

The invention discloses a method and device for copying incremental data, and belongs to the field of internet communication. The method includes the steps that write data requests are received; data to be written in and period identification of a current period are bound, and the data to be written in are stored in a first storage medium according to offset addresses of the data to be written in; data received in the current period are acquired according to the period identification of the current period; the data received in the current period are stored in a second storage medium, wherein the write data requests carry the data to be written in and the offset addresses of the data to be written in. The device comprises a receiving module, a binding module, a first storage module, an acquisition module and a second storage module. According to the method and device for copying the incremental data, the data to be written in and the period identification of the current period are bound by a server; when the data are copied, the data received in the current period are acquired according to the period identification, the received data are stored in the second storage medium, and the copying process is simple.

Description

technical field [0001] The invention relates to the field of Internet communication, in particular to a method and device for incremental data copying. Background technique [0002] In recent years, with the development of Internet communication technology, the amount of data generated has grown at an incredible rate. If data is lost, there will be serious consequences. Therefore, how to realize data backup is the focus of the industry. [0003] At present, the method of incremental data copy is mostly used for data backup, wherein, incremental data refers to newly stored data within a preset time; incremental data copy refers to copying incremental data from one storage medium to another in the storage medium. [0004] The prior art provides a method for incremental data copy, which may be as follows: the server receives a request for data to be written, and the request for data to be written includes the data to be written and the offset address of the data to be written;...
