Problems solved by technology

The disadvantage of this method is that once the local log file is damaged or lost, it will not be possible to perform incremental backup of the files that have been changed from the last incremental backup to the current one.

Embodiment Construction

[0019] The method of the present invention is described in detail below with reference to the accompanying drawings.

[0020] The system structure of the invention mainly includes: a file incremental backup application system, a file filtering drive system, and a remote storage system.

[0021] Among them, the file incremental backup application system is the main carrier for the realization of the strategy, which is responsible for the cooperation and scheduling of the file filtering drive system and the remote storage system, including the setting of rules and the realization of the strategy. The file filtering driver system is the core implementation module of this strategy, which is responsible for intercepting file change information in the file system and generating log files. The remote storage system is responsible for storing log file information of file changes.

[0022] The implementation method of the fast and reliable file incremental backup strategy is described...

Abstract

The invention provides a fast and reliable file incremental backup method. A system comprises a file incremental backup application system, a file filter driving system and a long-distance storage system. The file incremental backup application system is a main carrier for achieving a strategy, is responsible for scheduling and making the file filter driving system and the long-distance storage system coordinate with each other and comprises rule setting and strategy achieving, the file filter driving system is a core achieving module of the method and is responsible for intercepting generation of change information and log files of files in a file system, and the long-distance storage system is responsible for storing log file information of file changes.

Description

technical field [0001] The invention relates to a computer application technical field, in particular to a fast and reliable file incremental backup method. Background technique [0002] The pace of global informatization is getting faster and faster, and the total amount of data is growing rapidly, so the security of data storage is becoming more and more important. While informatization brings people fast service and convenient management, it also brings people the risk of digital information loss, so the status of data backup is becoming more and more prominent. [0003] There are three main methods of data backup: full backup, incremental backup and differential backup. [0004] Full backup (full backup), each file will be written into the backup file. As mentioned above, if there is no change in the data between two point-in-time backups, then all backup data is the same. The problem is that the backup system doesn't check whether the files have been changed since th...
