Problems solved by technology

However, when enterprises migrate their services to cloud computing, they are often afraid because they have lost control of their sensitive data and can only rely on cloud computing service providers to ensure data security.
Hardware failure, human error, software defect, computer virus, hacker attack, natural disaster and many other factors may cause data loss, thus causing incalculable losses to the enterprise
The OpenStack cloud platform itself provides some basic data protection functions such as snapshots and virtual machine reconstruction for virtual machines, but it cannot perform file-level backup and recovery, and once the cloud platform itself fails, data will be at risk of loss

Embodiment Construction

[0047] The present invention provides a virtual machine backup method based on a distributed storage system, such as figure 1 As shown, the methods include:

[0048] S1. Configure distributed storage, convert rbd through the iscsi tool, and map it to the backup server;

[0049] S2. Log in to the backup server, and the backup server automatically scans the iscsi storage; the distributed storage is recognized and utilized by the backup server after being converted by iscsi;

[0050] S3. The backup server creates a virtualized stripe based on the scanned physical storage to save the backup data;

[0051] S4, configure the information of the KVM virtual machine in the OpenStack, and set the backup strategy;

[0052] S5. Start the backup according to the backup strategy, and back up the data information inside each virtual machine to the distributed memory; the data information includes: files, database tables, and virtual machine operating systems;

[0053] S6. When a virtual m...

Abstract

The invention provides a virtual machine backup method and system based on a distributed storage system. When the virtual machine crashes, the virtual machine reconstruction function based on OpenStack platform is selected to rebuild the failed virtual machine, and the data information of the rebuilt virtual machine is restored from the backup server. In this way, even if the virtual machine crashes, the previous data files can be recovered, and the process data of the virtual machine can be backed up. The method and the system of the invention butt the open source distributed storage system ceph, and realize the backup of the KVM virtual machine in the OpenStack cloud management platform to the distributed storage system, thereby solving the backup of the KVM virtual machine with different granularity, and reducing the backup cost.

Description

technical field [0001] The invention relates to the field of computer networks, in particular to a virtual machine backup method and system based on a distributed storage system. Background technique [0002] With the advantages of reducing costs, improving operational efficiency, and accelerating the pace of enterprise innovation, OpenStack is widely supported by enterprise users. Since its inception in 2010, OpenStack has grown into one of the most successful open source projects recognized by the industry, and it is also the largest open source platform in history. According to incomplete statistics, OpenStack users include 50% of Fortune 100 companies, managing 5 million processor cores. Today, the users who adopt OpenStack are more and more diverse. They come from various fields, from exploring astronomy, to telecommunications, finance, to automobile manufacturing, etc., in any subdivided industry. However, when enterprises migrate their services to cloud computing, t...
