File back-up system and method of computer system

Abstract

The invention relates to a method of file backup in a computer system and a system thereof. The method comprises the following steps: step 1, a monitoring device captures a file operation event in the computer system, generates a file operation log for the file operation event which is within the monitoring range, matched with filter rules and successfully executed, and stores the file operation log into a memory device; step 2, a backup control device schedules the execution of a backup task, and transmits the backup task to a backup device when the backup task needs to be executed; step 3, the backup device judges whether the backup task is full backup or incremental backup, if the backup task is the full backup, then the full backup is carried out, otherwise, the next step is executed; and step 4, the backup device acquires the file operation log from the memory device and carries out the incremental backup according to the file operation log. The method can carry out online data warm backup, provides an incremental backup method for file logical blocks, reduces backup data volume and improves the backup efficiency.

Description

technical field [0001] The invention relates to the field of information security, in particular to a system and method for file backup in a computer system. Background technique [0002] With the continuous development of computer technology and the continuous improvement of informatization, people's dependence on information is getting higher and higher. The highly centralized storage of information in the IT environment greatly improves the automation of information and data management, improves operational efficiency, and reduces costs. But at the same time, the risk is also increasing, and data loss caused by disasters may cause huge losses. [0003] In order to avoid the adverse effects of disasters, it is necessary to back up data regularly or in real time. As the data to be protected continues to increase, the time required for a data backup is getting longer and longer. Business applications are constantly busy, and their importance is increasing. The time that bu...

Problems solved by technology

This method reduces the amount of backup data to a certain extent, but for the case of partial file changes, the amount of backup is still relatively large

[0008] Patent CN1773500A proposes a method and system for performing backup of the current file system relative to the previous file system backup using directory-style hard links of the computer file system, but does not propose a method for backup efficiency
