Problems solved by technology

However, this dumping strategy lacks certain rationality. Specifically, due to the slow access speed of low-level data storage clusters, if the data stored for a long time but frequently accessed by users is dumped to lower-level data Storage clusters can easily lead to slow data access speeds, thereby reducing the user's data access experience

Embodiment Construction

[0038] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. the embodiment. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0039] For ease of understanding, the following first describes a big data storage system, such as figure 1 Shown as the application scenario of this embodiment. In a big data storage system, the data management server is usually connected to multiple levels of data storage clusters, figure 1 Take three levels of data storage clusters as an example. The data management server is u...

Abstract

The invention provides a data restoring method, an apparatus and a data management server, which relate to the technical field of big data, wherein, the method comprises the following steps: acquiringan access frequency of data in a first data storage cluster; determining whether data need to be restored according to the frequency of access; in the event that it is determined that the data needsto be restored, the data being restored from the first data storage cluster to a data storage cluster at a level matching the access frequency. The invention determines the restorage strategy of dataaccording to the access frequency of the data, which can reduce the storage cost of the large data, distribute the storage data more reasonably, ensure that the data with high access heat degree can be accessed quickly, thereby improving the data access experience degree of most users.

Description

technical field [0001] The invention relates to the technical field of big data, in particular to a data transfer method, device and data management server. Background technique [0002] In the field of big data, data scheduling is a basic requirement. For example, when performing data backup, copy data from a high-level data storage cluster to a low-level data storage cluster to prevent accidental deletion of data. Since the storage cost of the high-level data storage cluster is relatively high, in order to reduce the data storage cost as a whole, some data is transferred from the high-level data storage cluster to the low-level data storage cluster. [0003] In a related manner, the data transfer policy is determined according to the storage time of the data. Usually, when data is newly generated, it is often stored in a high-level data storage cluster. Due to the limited space and high cost of a high-level data storage cluster, if some data is stored for a long time, it...
