跨云环境的备份及容灾管理分析与实践

Analysis and practice of backup and disaster recovery management across cloud environments

随着电网企业智能化步伐的推进,IT在电网企业的地位越来越重要,作为关系到国计民生的重要行业,电力行业一旦发生大规模数据损失或破坏,所造成的损失将是无可估量的。特别是在云时代的背景下,如何保障部署在云服务器上的电力业务系统,在遭受火灾、洪水等意外灾难的破坏后,可以及时恢复并保障业务的持续运作,是当前急待解决的重要问题。本文阐述了电网企业在跨云环境下备份及容灾管理所遇到的困难和挑战,并阐述了电网企业如何采用集群、远程镜像技术、基于IP的SAN的互连技术、快照技术和异地“双活”等技术,一旦机房遭受灾难时,业务即时迁移到备机,能够实现零停机,确保业务的连续运行,即使在灾难后,也能够通过备份及容灾恢复业务,可以方便地挽回丢失的数据,把灾难带来的风险和损失降到最低。

With the pace of intelligent advancement of power grid enterprises,the importance of IT in power grid enterprises has become more important.As an important industry related to national economy and people’s livelihood,once large-scale data loss or destruction occurs,the losses will be incalculable.Especially in the context of the cloud era,how to ensure that the power business system deployed on the cloud server can recover and guarantee the continuous operation of the business in time after being damaged by accidents such as fires and floods is an important issue to be solved urgently.problem.This paper describes the difficulties and challenges faced by grid enterprises in backup and disaster recovery management in a cross-cloud environment.It also explains how grid enterprises adopt clustering,remote mirroring technology,IP-based SAN interconnect technology,snapshot technology and off-site.In the case of a disaster in the equipment room,the business is immediately migrated to the standby machine,enabling zero downtime and ensuring continuous operation of the business.Even after the disaster,the business can be recovered through backup and disaster recovery,which can be easily recovered.Lost data minimizes the risks and losses of disasters.
