Problems solved by technology

[0005] The existing solution realizes data redundancy by the application layer. According to the characteristics of the application layer, its logic is relatively complicated, and it is necessary to analyze the operation of the application layer layer by layer and send it to the bottom layer for implementation; Redundant backup is triggered only after the master device writes data successfully, which is not timely enough and slow

example

[0065] see figure 2 , is an example of an initialization processing flow chart of cloud storage-based data redundancy backup in the present invention, which includes the following steps:

[0066] In step 201, the initialization application unit of the storage node server receives an initialization instruction from the master device, and selects a redundant device for the master device.

[0067] In step 202, the initialization application unit includes the main device GUID and the redundant device GUID in the redundancy initialization command and sends it to the redundant drive unit.

[0068] Further, the GUID of the master device may also be written into the agreed position in the redundant device, and the GUID of the redundant device may be written into the agreed position in the master device.

[0069] Step 203, the redundant drive unit sets the device states of the primary device and the redundant device to the initializing state, the redundant drive unit establishes and ...

Abstract

The invention discloses a cloud storage-based data redundancy backup method, system and storage node server, wherein the method includes: the redundant drive unit of the storage node server monitors the write operation command; The write operation command for writing data obtains the globally unique identifier GUID of the master device; the redundant drive unit finds the corresponding redundant device GUID in the mapping relationship according to the master device GUID; the redundant drive unit determines that it corresponds to the redundant device GUID The redundant device is online, and the data written to the master device is written to the redundant device. The scheme of the present invention can realize real-time and fast redundant backup, and avoid the logic complexity realized by the upper layer application.

Description

technical field [0001] The invention relates to cloud storage technology, in particular to a cloud storage-based data redundancy backup method, system and storage node server. Background technique [0002] Cloud storage refers to a storage solution that integrates a large number of storage devices in the network through application software to work together through cluster applications, grid technology, and distributed self-storage file systems to jointly provide data storage and business access functions. The cloud storage system includes a storage node server and multiple node devices for data storage, and the storage node server is used for redundant management and maintenance of each node device in the system. The cloud storage system also includes other devices, such as an index server, for fast retrieval of information stored in the storage node server. [0003] In cloud storage, data redundancy backup is often involved, and the data of some node devices needs to be b...
