Embodiment Construction

[0040] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0041] 1. The present invention provides a distributed backup method for files. The files include ordinary files and directory files. See figure 1 After receiving the backup instruction, that is, the backup path, the file will be backed up to the designated folder of the local computer, and several entries will be synthesized, and inserted into the backup database using the current employee number, current time, backup path and entry A record; get all the network clients connected to the network from the network client system, randomly select one or more network clients from all the network clients, back up the above entries to the selected computer network clients, and Copy backup records to network clients. In this way, after the current user's computer is completely damaged, the previously backed-up files can be restored from other networ...

Abstract

The invention discloses a distributed backup method of files. The files comprise common files and catalogue files. The method comprises the following steps: backuping the files to a specified folder in a local computer after receiving a backup instruction, namely, a backup path, and simultaneously synthesizing a plurality of entries, and inserting into a backup record; copying all backuped objects and the backup record to one or more network clients communicated with the local computer, wherein the entries comprises Hash values, file types, attributes, modified dates and file names; the backup record comprises employee numbers, current time, backup paths and entries. The network client is used for saving the computer backup, so that a backup system is unnecessary to configure a dedicated server, the hardware cost is lowered, the personnel cost is lowered, each backup has a plurality of duplicates on a plurality of computers; according to the setting of the duplicate number, any computer damage not more than the duplicate number can recover the backup file; the disaster tolerance ability is better than that of a normal server backup file.

Description

technical field [0001] The invention belongs to the technical field of computer storage, and relates to a distributed file backup method and system. Background technique [0002] The common methods of current computer file backup software are as follows: 1. Compress the files and directories to be backed up into a single compressed package such as zip or rar, or directly copy another copy. The disadvantage of this method is that after backup It takes up a lot of disk space, because the same file will be saved multiple times for each backup; 2. The backup software of the stand-alone version saves the backup to the local computer. The disadvantage of this method is that once the computer hard disk is damaged (it cannot be repaired) , all files and backups will be lost; 3. The backup software of the stand-alone version will save the backup to storage devices such as U disk and mobile hard disk. The disadvantage of this method is that it is necessary to manually insert the U dis...
