Method for filtering monitored directory change events

Abstract

The invention provides a method for filtering monitored directory change events. A system comprises a file monitoring event module, a file interceptor module, an event interceptor module and a file copying module. The functions and processing steps of the modules are as follows: to protect the specified file directories, the file monitoring event module first specifies the file directories to be protected and adds the file directories to the file monitoring list; the file monitoring event module (1) monitors the change of any file in the directory in real time after starting monitoring the directory; addition, deletion and alteration of the files in the directory can trigger a file monitor to notify a file protection module in accordance with the events generated by file change, therefore, file backup can be carried out to achieve the purpose of file protection. Applied to data backup systems, the method can increase the disk backup utilization ratio and save the backup space, thus coping with the challenges which sharp increase of data faces. In particular, based on network backup, the network bandwidth occupation can be greatly reduced, thus greatly improving the backup efficiency.

Description

technical field [0001] The invention is a monitoring directory change event filtering technology, which is usually used in a file-based backup system and aims at reducing the number of file backups in incremental backups. The "monitoring directory change event filtering" technology can reduce the stored data to 1 / 10 of the original, so as to allow more backup space, not only can save the backup data on the disk for a longer time, but also save offline A large amount of bandwidth is required for storage. technical background [0002] Insufficient storage space has always been a headache for IT personnel, because not only do they need to purchase additional storage devices, but they also have to face various configuration tasks that follow after adjusting the storage architecture. Needless to say, these tasks are complicated and cumbersome. In the process of expanding storage capacity, downtime is more likely to be required, which will seriously affect the normal operation of...

Problems solved by technology

But when encountering problems, the operating system often generates more than one event notification after a file change, sometimes as many as a dozen. If these event notifications are used, the file may need to be backed up more than a dozen times. Obviously, both in terms of efficiency and Huge problem in terms of disk space usage
