An Efficient File Backup and Recovery Method

Abstract

The invention discloses an efficient file backup and recovery method. The technical problem to be solved is to change the traditional backup method under the premise of normal system operation, speed up file backup or recovery and save storage space. Can accurately and efficiently restore the required files. Technical solution: As time goes by, the change of the file leads to a new file version. The new version can be formed by combining the change data of the file with the previous file version. When saving the change data of the file, it can be divided into continuous storage blocks and stored in In the medium, if the data of the storage block is the same as that of an existing storage block, it does not need to be stored repeatedly. The memory assigns a unique ID to the storage block, and the recovery file operation is realized through the collection of these IDs. The present invention does not need to repeatedly store the same data block, saving storage space; it does not need to perform operations such as data copying and pasting, and improves recovery speed and efficiency.

Description

technical field [0001] The invention relates to a file backup and recovery method, which is a fast, reliable backup and recovery method that can save storage space. Background technique [0002] The popularity of computers has brought a lot of convenience to daily work and life, but when computers are attacked or natural disasters, people are in a hurry in the face of lost important data. Faced with such a difficult problem, people often use the following methods: 1. Use an external device to copy the data; 2. Use a recorder to burn the data into a CD; 3. Save the data outside the system partition; 4. Back up the data with a floppy disk; 5. Use GHOST to backup data or system. Although the above five methods can protect important data to a certain extent, problems such as inconvenient operation, easy misuse, loss of external devices, and waste of resources are endless, and they are not suitable for enterprises with large amounts of data. [0003] Some enterprises need to pe...

Problems solved by technology

Although the above five methods can protect important data to a certain extent, problems such as inconvenient operation, easy misuse, loss of external devices, and waste of resources are endless, and they are not suitable for enterprises with large amounts of data.

[0003] Some enterprises need to perform regular backups. When the amount of data grows relentlessly, this will inevitably require more storage space and more bandwidth. Managers will not want to easily destroy the original data structure, but this requires more hardware investment
