110: Commercial Server 120: Backup Agent

130: backup server

The present invention relates to a method and system for providing a data backup solution of a commercial server. More specifically, by managing the usage status of the commercial server in real time, the data is backed up only when the commercial server is in a certain level or lower, and when the level is above a certain level, the backup of the data is paused to decrease the performance of the commercial server. The present invention relates to a method and a system for performing a backup while preventing a problem.

In general, a server is a subsystem that services data-intensive processing in a communication network. The server performs printer control or file management to monitor / control the entire network, or to communicate with other networks through a mainframe or public network. It helps to share software resources such as connections, data, programs and files or hardware resources such as modems, faxes, printer sharing and other equipment.

Such a server provides various services to the user. The connection structure between the server and the client is called a client / server system. A client / server system refers to a distributed form of operating one or more applications in a mutually cooperative environment. The client / server system provides a user with a desired service through collaboration between a client requesting a service and a server processing the client's request. System.

In the case of small LAN with 5 ~ 20 clients, all the services can be handled by one server. However, in the case of more large LAN, multiple servers are arranged. The exchange with the outside such as the printer server, the Internet, etc. is divided into respective roles such as the communication server.

On the other hand, the server on the Internet is a special form of a computer that provides information stored on the user's hard disk to the outside. In general, in the Internet, various information is managed by a server, and general users use their computers to access the server and use information provided by the server.

As such, a system that provides various services using a server always performs a task of backing up and storing important data periodically. Here, the backup of data refers to a series of operations for periodically transferring important data to a specific backup server or storage device in order to use it when an important file is lost in the system and needs to be urgently recovered.

Conventionally, backup of data is performed without considering the state of a commercial server by using FTP (File Transfer Protocol) or RCP (Remote Copy Protocol) commonly used for file transfer between a dedicated backup server and a commercial server of a service system. As a result, there was a problem of overloading the system resources of a commercial server.

That is, since the backup server determines the transmission speed of the backup data and whether or not the transmission is interrupted without considering the state of the commercial server, the commercial server excessively allocates resources to the transfer of the backup file, resulting in degradation of function or There was a case in which the system itself failed and the original function could not be faithfully performed.

Data backup solutions such as this can overload the central processing unit (CPU) of a commercial server with excessive transfer of backup files, occupy too much memory resources, or fail to secure minimum disk space at times of high disk utilization. This can cause serious problems such as performance degradation or system downtime.

In addition, when the commercial server performs data processing through the network to transmit the backup data, the backup of the data should be stopped until the commercial server secures an appropriate level of network bandwidth. There was a problem that the I / O (Input / Output) of the data can not be performed, causing the system to run out of resources, threatening the stability.

In order to solve the above-mentioned problem, the present invention manages the use state of a commercial server in real time, and performs data backup only when the use state of the commercial server is below a certain level, and temporarily backs up the data when a certain level or more is reached. The goal is to provide a method and system for performing backups while stopping to prevent performance degradation of commercial servers.

In order to achieve the above object, the present invention includes a backup server for performing a backup of wired and wireless service data, the server system for providing a wired and wireless service to a user, the user and the wired and wireless service data to the user by transmitting and receiving Providing the wired / wireless service, and including a backup agent which determines usage status information in real time and determines whether to back up the wired / wireless service data based on the usage status information, and controls the wired / wireless service data under the control of the backup agent. It provides a data backup system comprising a commercial server to back up to the backup server.

In addition, according to another object of the present invention, in a server system comprising a backup server for performing the backup of the wired and wireless service data and a commercial server for transmitting and receiving wired and wireless service data with the user to provide a wired and wireless service, a method for backing up the wired and wireless service data A method comprising: (a) collecting usage state information; (b) analyzing the usage state information to determine whether the usage state is below a threshold; And (c) backing up the wired / wireless service data to a backup server when the usage state is less than the threshold as a result of the checking in step (b).

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. First of all, in adding reference numerals to the components of each drawing, it should be noted that the same reference numerals are used as much as possible even if displayed on different drawings. In addition, in describing the present invention, when it is determined that the detailed description of the related well-known configuration or function may obscure the gist of the present invention, the detailed description thereof will be omitted.
