Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
As shown in fig. 1, the data security backup system provided by the present invention includes a main server and a backup server, where the main server and the backup server adopt a dual-server hot standby deployment manner.
The main server and the backup server are connected through an Ethernet TCP/IP protocol.
A data security backup method comprises the following steps:
step 1, copying data in a main server to a backup server in real time by using a data real-time mirroring method; monitoring the running state of application resources in real time, wherein the running state of the application resources comprises network speed, CPU utilization rate, memory utilization rate, hard disk active time and memory read-write speed;
step 2, according to the running state of the application resources monitored in the step 1, carrying out intelligent early warning and strategy switching; for example, when the network card or network resource fails, the resource is automatically switched to the backup server. The method is used for realizing automatic switching when resources (mainly hardware) fail and solving single-point failures of software and hardware, thereby ensuring continuous operation of a service system; the running state of the application service (database service program, SQLserver 2008R 2) is monitored in real time, and when the application service is abnormal, the application service is automatically switched to the backup server.
The specific method for performing policy switching is as follows:
and when the main server cannot be started, the backup server performs machine activation through software diagnosis and test.
The method is used for ensuring that an application service (database service program, SQLserver 2008R 2) is online and continuously mirroring and copying data; IO changes (database data changes, such as weighing data for completing weighing storage, operation log data and the like) of any data source are automatically copied to the target host, so that consistency of the data source and the data backup at any time is ensured.
The data safety backup system is an important information system for enterprises, and two servers are used for mutual backup and common execution of the same service. When one server fails, the other server undertakes tasks, so that the system can be automatically ensured to continuously provide services without manual intervention. The dual-computer hot standby solves the problem of uninterrupted service when the main server fails by the standby server.
The dual-computer hot standby is particularly a server hot standby based on an active/standby mode. Server data, including database data, may be written to two or more servers simultaneously, or using a shared storage device. Only one server is running at the same time. When one running server fails and cannot be started, the other backup server activates the standby machine through software diagnosis (generally through heartbeat diagnosis), and the application is guaranteed to be completely recovered to normal use in a short time.
The data safety backup system method comprises the following steps: the method comprises the steps that main and standby dual-computer deployment is adopted, data (weighing service data stored in a database) of a service data host computer are copied to a standby host computer in real time through a data real-time mirroring technology based on an Ethernet TCP/IP protocol; and the running state of the application resources, including network speed, CPU utilization rate, memory utilization rate, hard disk active time, memory read-write speed and the like, can be monitored in real time, intelligent early warning and strategy switching can be carried out, network resources, such as a service network card or network resource faults, can be continuously monitored, and the resources can be automatically switched to available standby machines. The automatic switching is realized when the resource (mainly hardware) fails, and the single-point failure of the software and the hardware is solved, so that the continuous operation of a service system is ensured. And monitoring the running state of the application service (database service program, SQLserver 2008R 2) in real time, and automatically switching the application service to a standby machine if the application service is abnormal.
Data plays a crucial role in enterprise production and management, and is information that is relied on and indispensable for all business activities, such as enterprise, production, management, strategy, and the like. The data is just like the eyes of an enterprise operator, and the operation problem can be reflected through the data just like a rudder depends on navigation.
The data types can be divided into: financial data, production data, sales data, market data, human resources data, and the like, and the various data may play different roles. The roles of financial data, production data, and sales data are all necessary and all are vital, missing data, or not statistically significant. The enterprise manager, is just like blind pass the road.
Data security is crucial to the normal operation of enterprises today. Enterprises need to do data security work practically, and major loss is avoided. In addition, if the security of the data is not sufficient, this can result in customer distrust of the enterprise, which can also have negative effects.
In the background of the era of big data, enterprises should strengthen the management of the final line of defense of business continuity and data security to deal with unknown risks. Various embodiments are enumerated
The data safety backup system mainly aims at the task of data host hot backup (after the two-computer hot backup is set, after the data host hot backup is stored, the task is called to create one task, a plurality of tasks can be created, and the backup of data between different two computers can be completed, for example, the task of creating database backup, the task of creating document backup between two computers and the like) can be operated through a toolbar or a right key shortcut.
The main operations used are as follows:
carrying in: can make the task effective
Taking out: the task can be disabled
Taking over or transferring: the active host may be switched.
Modification/viewing: the configuration information for the task may be modified.
After the main machine and the standby machine are switched: the application service database service program only runs on the server which is taken over (can be viewed in the computer service);
stop running on the standby machine (can be viewed at the computer service center).
