Policy scheduling method and policy scheduling system

Abstract

The invention discloses a strategy scheduling method and a strategy scheduling system. The strategy scheduling method comprises the following steps: obtaining a strategy and a time slice; dividing a task corresponding to the strategy into task blocks according to task granularity within the time slice, and executing the task according to the strategy with the task granularity as a unit; when the time slice is used up, continuing to execute and accomplish the task block when the time slice is used up; and switching the strategy. According to the strategy scheduling method disclosed by the invention, the task corresponding to the strategy is divided into the task blocks according to the task granularity within the time slice, the task is executed with the task granularity as the unit, and when the time slice is used up, the strategy is switched after the task block is executed and accomplished when the time slice is used up, therefore throughput performance of data backup is improved.

Description

Technical field [0001] The present invention relates to the field of computer technology, in particular, to a strategy scheduling method and strategy scheduling system for data backup. Background technique [0002] The strategy is the information for the user to set the backup operation, and it is also the core of the backup system. Strategic scheduling is to perform system backup operations according to policies. It is the key to ensure fair scheduling of strategies in application requirements. At the same time, high-performance throughput is required. [0003] An existing strategy scheduling method is to perform time slice polling on the strategy based on time slice. Time slice polling means that tasks are executed according to the strategy in the time slice of the strategy. If the task in the time slice of the strategy is always executed, the next strategy will be traversed when the time slice is exhausted. [0004] The existing strategy scheduling method of the backup system ...

AI Technical Summary

Problems solved by technology

[0006] Aiming at the problem in the related art that the policy scheduling method when the time slice is exhausted and when there are no tasks under the policy leads to poor throughput performance of data backup, the present invention proposes a policy scheduling method and a policy scheduling system, which can improve data backup throughput performance
