Description

结构化灾难备份系统和备份方法 Structured disaster recovery and system backup method

技术领域 FIELD

[0001] 本发明涉及数据库备份技术,跟具体地说,涉及结构化的灾难备份系统。 [0001] The present invention relates to a database backup technology, with in particular, to the structure of the disaster recovery systems.

背景技术 Background technique

[0002] 通常,对于大型的数据库,都需要配备灾难备份系统,灾难备份系统在物理位置上与主系统隔离,并且需要隔开相当的距离,以实现在主系统由于某种原因无法工作时,可以接管主系统的工作,继续提供服务。 [0002] Generally, for large databases, backup systems are required with a disaster, a disaster backup system and the primary system on the physical separation, and requires a considerable distance apart, in order to achieve the primary system is not working for some reason, can take over the main system, we continue to provide services.

[0003] 由于灾难备份系统需要与主系统实现相同的工作,因此备份中心需要配置与主系统同一系列、性能档次接近的主机及相应的数据库。 [0003] Since the disaster recovery system needs to achieve the same work with the host system, so the backup central host system to configure and the same series, the performance level close to the host and the corresponding database. 在传统的备份中心配置中,使用数条(比如两条2M的)专线与主系统相连,利用数据库的日志备份与恢复机制来进行主系统与备份系统之间的数据同步。 In conventional backup center configuration, a number of (for example two of 2M) and the main line system is connected, for data between the main system and the backup system synchronization using log database backup and recovery mechanisms.

[0004] 更具体地说,可以在主系统的数据库服务器后台运行监控进程,每隔十分钟检查是否有新的归档日志需要传送。 [0004] More specifically, the database server process runs in the background to monitor the main system, every ten minutes to check for new log file to be transferred. 一旦有新的日志文件生成,就立即传送到备份系统,同时每天分三次在备份系统中将新传入的日志在备用数据库中进行恢复。 Once a new log file is generated, it is immediately transferred to the backup system, the backup system while three times in a day, the new incoming logs for recovery in the standby database. 这样,两地的数据差异将保持在一个日志文件(127M,约3万条交易记录)以内,实现了两地数据间的"准同步"。 Thus, the data differences between the two will remain within a log file (127M, about 30,000 transaction records), to achieve a "quasi-synchronous" between the two places data. [0005] 采用传统的备份方案,存在如下的缺点: [0005] traditional backup scheme, there is a disadvantage:

[0006] 1)该方案的仅能实现"准实时"的数据同步。 Only [0006] 1) implementation of the program "quasi real time" data synchronization. 当主系统出现灾难无法读取硬盘数据时,将会有一部分数据的丢失(最多可能是一个日志文件127M,约3万条交易记录)。 When the primary system hard drive can not read data disaster occurs, there will be a loss of part of the data (most probably a log file 127M, about 30,000 transaction records). 当数据库对于实时服务具有较高的要求时,或者交易记录具有不可再现性时,数据库的运行会受到显著的影响。 When the database for real-time services with higher requirements, or when the transaction has not reproducible, run the database will be significantly affected.

[0007] 2)目前的备份策略都是整体切换备份,即,主系统中的任意一个部件出现故障,当其会影响到主系统的整体运行时,主系统的整体都切换到备份系统运行。 [0007] 2) the current backup strategies are entirely switched backup, i.e., the main component of any one system fails, as it will affect the overall run time of the main system, the overall primary system to the backup system are switched operation. 这样的备份策略显然需要花费更多的时间,目前的备份时间通常都在几十分钟到几十小时,同样,对于实时服务具有较高要求的数据库,会明显感受到备份切换带来的影响。 Such a backup strategy obviously takes more time, the current backup time is usually in the tens of minutes to several hours, the same, the service has a database for real-time high requirements, you will clearly feel the impact of a backup switch.

具体实施方式 Detailed ways

[0043] 首先参考图l,本发明的结构化灾难备份系统的主要设计思想是将系统模块化,以便于在进行备份切换时可以局部进行,加快备份的速度。 [0043] Referring first to Figure L, the main structural design of the disaster recovery system of the present invention is a modular system, so that it can be partially switched on during a backup, the backup speed. 如图l所示,该结构化灾难备份系统包括一主系统10和一备份系统20,主系统10包括互相连接的服务器子系统11、存储子系统12、网络子系统13和通讯子系统14,备份系统20包括: As shown in FIG. L, the configuration of the disaster recovery system 10 includes a main system and a backup system 20, the main system 10 includes a server 11 interconnected subsystems, the storage subsystem 12, subsystem 13 and communications network subsystem 14, backup system 20 includes:

[0044] 服务器备份子系统21,对应于服务器子系统ll,并且与存储子系统12、网络子系统13和通讯子系统14实现连接; [0044] 21 server backup subsystem, the server subsystem corresponding to ll, and 12, the network subsystem and communication subsystem 13 is connected to the storage subsystem 14 implements;

[0045] 存储备份子系统22,对应于存储子系统12,并且与服务器子系统11、网络子系统13和通讯子系统14实现连接; [0045] The backup storage subsystem 22, corresponding to the storage subsystem 12, subsystem 11 and the server, the network subsystem 13 and communication subsystem 14 implements the connection;

[0046] 网络备份子系统23,对应于网络子系统13,并且与服务器子系统11、存储子系统12和通讯子系统14实现连接; [0046] network backup subsystem 23, subsystem 13 corresponds to a network, and the server sub-system 11, the storage subsystem 12 and communication subsystem 14 implements the connection;

[0047] 通讯备份子系统24,对应于通讯子系统14,并且与服务器子系统11、存储子系统12、网络子系统13连接; [0047] The backup communication subsystem 24, corresponding to the communication subsystem 14 and subsystem 11 with the server, the storage subsystem 12, subsystem 13 is connected to the network;

[0048] 其中,所述服务器备份子系统、存储备份子系统、网络备份子系统和通讯备份子系统之间互相连接; [0048] wherein the interconnection between the backup server subsystem, a backup storage subsystem, a backup subsystem and network backup communication subsystem;

[0049] 当主系统10中的一个或数个子系统故障时,如果该故障并不需要进行整体的切换,则仅仅将发生故障的子系统切换到备份系统中相应的子系统,而主系统中没有发生故障的子系统继续使用。 [0049] When the number of subsystems or a fault in the main system 10, if the fault does not require the entire handover, only the malfunctioning subsystems switch to the backup system, the occurrence of the corresponding subsystem, the master system does not subsystem failure to continue to use. 比如,当主系统10中的服务器子系统11出现故障时,仅仅使用备份系统20中的服务器备份子系统21来替代该服务器子系统ll,而主系统10中的存储子系统12、网络子系统13和通讯子系统14则继续使用。 For example, when the primary server sub-system 10 11 failure, server 20 using only the backup system backup subsystem 21 instead of the server sub-ll, the main system 10 and the storage subsystem 12, subsystem 13 network and continue to use the communication subsystem 14. 由于主系统10中的服务器子系统11、存储子系统12、网络子系统13和通讯子系统14和备份系统20中的备份服务器子系统21、备份存储子系统22、备份网络子系统23和备份通讯子系统24都是实现互联的,因此备份服务器子系统21可以方便地接替服务器子系统11继续工作。 Since the server 10 in the main system subsystem 11, memory subsystem 12, the backup server 20 network subsystem 13 and communication subsystem 14 and subsystem 21 backup system, the backup storage subsystem 22, subsystem 23 and backup network backup communication subsystem 24 are interconnected, so the backup server subsystem 21 can easily take over the server subsystem 11 to continue working. 仅仅替换主系统10中的一个部件所需要进行的操作比对主系统10进行整体替换要简单地多,也可以节省大量的时间,因此,本发明通过上述的模块化设计使得进行部分备份切换时的切换时间能够縮短到几分钟甚至是几秒钟。 When replacing only a main system operation member 10 required to be simple than the overall primary system 10 Alternatively, can save a lot of time, therefore, the present invention is a modular design such that the above partial backup switch the switching time can be reduced to minutes or even seconds. 当主系统10有多个部件故障,引起整体故障时,才将主系统10整体切换到备份系统20。 When the primary system 10 has a plurality of component failure causing total failure, the main system 10 as a whole will only switch to the backup system 20.
