Embodiment 1

[0039] This embodiment provides a file backup method, which is characterized in that it is applied to a communication network including a client and a server connected to the client in communication, and the file backup method includes the following steps:

[0040] Mounting a disk area on the server side on the client side by specifying a network protocol to form a virtual disk;

[0041] Select a backup data source in the disk area of ​​the client, and create a first data bitmap for monitoring changes in the input / output data of the backup data source on the memory of the client, and for exchanging the first data bitmap a second data bitmap of the change status of the input / output data in the first data bitmap;

[0042] Initially scan the system bitmap of the backup data source, read the input / output data in the backup data source, and copy the read input / output data in the backup data source to the virtual disk formed on the client ;

[0043] After the system bitmap scannin...

Embodiment 2

[0068] This embodiment provides a client 2, please refer to Figure 5 , which is a schematic diagram of the client’s principle structure. Such as Figure 5 As shown, the client 2 includes the file backup system 1 described in the first embodiment.

[0069] To sum up, the file backup method and system of the present invention and the client with the system record the system I / O changes by updating the bitmap, periodically synchronize the data by switching the update bitmap and exchanging the bitmap, and every Taking a snapshot of the backed up data at regular intervals avoids the time-consuming operations of creating and comparing file feature description lists in traditional methods, and also avoids the time-consuming operations of frequently opening, reading, and closing files when backing up a large number of small files. Real-time operation can not only back up small files efficiently, but also ensure the reliability of data through periodic snapshots. Therefore, the pre...

Abstract

The invention provides a file backup method and system and a client. The file backup method comprises the steps that a disk area on a server is mounted on the client to form a virtual disk through a specified network protocol; a first data bitmap and a second data bitmap are created on a memory of the client; a system bitmap of a backup data source is initially scanned, input / output data in the backup data source is read, and the read input / output data in the backup data source is copied to the virtual disk; after scanning of the system bitmap of the backup data source is completed, the first data bitmap and the second data bitmap are monitored according to preset data backup parameters, switching to the second data bitmap is achieved through the changing condition of the input / output data in the backup data source recorded by the first data bitmap, and the changed input / output data is copied to the virtual disk according to the change of the second data bitmap. Accordingly, a time consuming operation is avoided, small files can be efficiently backuped, and the reliability of data is guaranteed.

Description

technical field [0001] The invention belongs to the field of data backup and disaster recovery, and in particular relates to a file backup method, a system and a client end with the system. Background technique [0002] With the rapid development of computer technology, most enterprises now use computers to operate their core business, and the resulting data has become the core wealth of enterprises. How to effectively protect these core data has become a huge challenge for enterprises. Challenge and focus. [0003] At present, the more troublesome and difficult thing for enterprise data protection is the backup of massive small files. In the actual IT working environment, there are often situations where the number of files is very large and the amount of data in each file is small, such as office files, picture files, and small videos. These files do not change frequently. For such an environment, the traditional incremental backup or differential backup method is very s...
