Embodiment Construction

[0041] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the present invention.

[0042] like figure 1 Shown is the work flow diagram of the multi-terminal backup service system of the present invention; figure 2 It is a flow chart of the task scheduling method of the multi-terminal backup service system of the present invention.

[0043] exist figure 1 Among them, the multi-terminal backup service system is realized by C / S architecture, including two parts: client and server. Among enterprise users, a disk array is usually set up in the enterprise network as the server, and all end users in the enterprise can be used as clients to connect to the server.

[0044] The main function of the client is to formulate a backup strategy for each user terminal, and form a backup task request according to the strategy. The backup strategy adopts the method of periodically backing...

Abstract

The invention discloses a multi-terminal backup service system and a task scheduling method thereof. The method includes: step 1, the client sets a backup policy for each user terminal, forms a task request according to the backup policy, and sends the task request to to the server; step 2, the server receives the task request, and sets an observation window of a certain length to sort the original task queue, and inserts the sorted tasks into the execution task queue in turn, and executes the task through the task processing node The tasks in the queue are processed to allocate corresponding task resources to the tasks. The present invention comprehensively considers the influence of multiple task attribute factors, can centrally and reasonably allocate concurrent tasks to processing nodes on the server side and assign corresponding task resources to them according to task characteristics, thereby reducing the task processing pressure and network load pressure on the server side.

Description

technical field [0001] The invention relates to the fields of computer information storage technology and data backup technology, in particular to a multi-terminal backup service system and a task scheduling method thereof. Background technique [0002] With the development of computer technology and personal PCs, a large amount of important data is scattered and stored in the computers of workers. These terminal devices are not safe, which can easily lead to data loss and bring losses to users. The terminal backup service system came into being. Backup service The system can not only save storage resources, but also greatly improve data security. The traditional terminal backup service system mainly backs up user data in chronological order, and the backup tasks are executed in a decentralized manner. When faced with a large amount of data from multiple users, users in the backup service system arbitrarily compete with each other for resource usage, resulting in network con...
