Problems solved by technology

This unified backup strategy does not take into account the differences between different data, which may lead to too much data redundancy in the system, relatively low storage efficiency, and poor system and cluster load balancing capabilities in practical applications.

Embodiment Construction

[0026] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0027] Such as figure 1 As shown, the number and location of each data backup are different, and data 1-5 are the data in 5 different clusters in the result of clustering. Backup rules can be formulated for each type of data as required. For data 1 (such as data that is not used for a long time and is not important), its backup rule can be formulated to be backed up only once on the local node. For data 2 (such as data that is rarely used and basically not modified), in order to ensure security, its backup rule can be formulated as the number of backups is 2, and the backup location is on different nodes of the same rack. For data 3 (for example, data that has a certain amount of usage and usage time and will be modified), its backup rule can be formulated as the number of backups is 3, and two copies are placed on different nodes o...

Abstract

The invention relates to a cloud computing platform data backup method based on clustering. The method comprises the steps: (1) identifying key factors according to user requirements; (2) introducing correlation rules to find association among the key factors, and determining the divided cluster number; (3) clustering data records containing the key factors; (4) in each time period, according to the step (3), setting the data backup number and backup position by taking a cluster as unit. A specific backup strategy containing the backup number and the backup position is made for data aiming at different usage situations of different data, the problem that too much data redundancy in a system to affect the load ability of the system is effectively solved, and thus the storage performance of the system or cluster is effectively improved.

Description

technical field [0001] The invention relates to the field of cloud computing, in particular to a data backup method for a cloud computing platform based on clustering. Background technique [0002] The data backup strategy is a corresponding backup management strategy formulated for the data backup requirements of different backup nodes. It is a set of rules defined by the system administrator on the management server for managing data security backup, archiving and hierarchical storage. After formulating a data backup strategy, you can back up data of different types and purposes according to the backup rules in specified numbers and locations. [0003] The current backup strategy on the cloud platform uses HDFS for data replication by default. The HDFS distributed file system adopts a unified backup strategy of three copies, and the backup location is specified. HDFS places two copies on different nodes of the same rack. , another replica is placed on a node in a differen...
