Embodiment Construction

[0035] The embodiment of the present invention provides a data protection method and device, which can be used in the application scenario of distributed storage cluster data storage, wherein the distributed storage cluster refers to a large number of PC servers interconnected through the Internet to provide an overall service to the outside world. And does not have the following characteristics:

[0036] (1) Scalable, the distributed storage cluster system can be expanded to a cluster size of hundreds or even thousands of units, and the overall performance of the system increases linearly.

[0037] (2) Low cost. Due to the characteristics of automatic fault tolerance and automatic load balancing in distributed storage clusters, distributed storage clusters can be built on low-cost servers, and the linear expansion capability also reduces server costs.

[0038] (2) High performance, regardless of whether it is for a single server or for the entire distributed storage cluster, ...

Abstract

The invention discloses a data protection method and equipment, which are used to solve the problem in the prior art that after a fault occurs in a fault domain, the performance of a distributed storage cluster is reduced and business operation is affected. In the embodiment of the present invention, the distributed storage cluster will re-divide the hard disks in the fault domains that have not failed to obtain at least one new fault domain, and reselect in the new fault domain according to the initial data fragmentation distribution rules The hard disks where data fragments are distributed, and recovery and rebalancing are performed on the reselected hard disks. Since in the embodiment of the present invention, after a fault occurs in a fault domain, the distributed storage cluster will re-divide the hard disks in the non-failure domain in time to obtain a new fault domain, and then the lost data will be based on the re-divided fault domain Recovery reduces the probability of performance degradation and business failure due to faults in the fault domain that cannot be processed in time.

Description

technical field [0001] The invention relates to the technical field of technical computers, in particular to a data protection method and equipment. Background technique [0002] With the explosive growth of data, traditional data storage methods can no longer meet the needs, and distributed storage has become the first choice. Distributed storage includes distributed block storage, distributed file storage and distributed object storage. [0003] Existing distributed storage clusters usually use data redundancy to protect data. Typical data redundancy methods include copy strategy and erasure code strategy. Both the copy strategy and the erasure code strategy will generate data fragmentation (such as copy, erasure code check block), the existing distributed storage cluster adopts the method of dividing the fault domain, and by formulating corresponding distribution rules, the data fragments are placed in different fault domains. Since the division of fault domains is art...
