Embodiment Construction

[0035] The embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. This embodiment is implemented on the premise of the technical solution of the present invention, and detailed implementation methods and specific operating procedures are provided, but the scope of protection of the present invention is not limited to the following the described embodiment.

[0036] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0037] 1. The method structure of mass file backup and recovery is as follows: figure 1 As shown, the entire backup set consists of the latest backup file directory and the incremental backup time point directory.

[0038] 2. Backup principle such as figure 2 as shown,

[0039] First, create an empty latest backup file directory, and then perform a full backup. The process of a full backup is the same as that of an increm...

Abstract

The invention discloses a method for fast backup and recovery of massive files, including: generating the latest backup file directory first, creating an incremental backup time point directory during incremental backup, and the invention does not record backup files in databases or files similar to database technology Metadata information, when judging incremental files, the system resource consumption is small and the speed is fast; when restoring, you can quickly find the file version that needs to be restored, avoiding the need to restore to a backup point that is close to the full backup, and restore to the current time. The speed of the backup point is slow. At the same time, the latest backup file directory is always consistent with the files that need to be backed up. When users need to restore or verify the latest backup data, they can directly use the latest backup file directory to meet the rapid recovery verification of massive file data. and temporary takeover needs.

Description

technical field [0001] The invention belongs to the technical field of data storage and backup, and specifically supports a method for fast backup and recovery of massive files. Background technique [0002] In the context of the rapid development of the Internet and the advent of the era of cloud computing, applications based on file-centric storage infrastructure (Web servers, emails, electronic records, electronic archives, and digital media) are occupying an increasing proportion of enterprise data. high ratio. IDC believes that 80% of the total shipments in the global storage market will be used to store unstructured data, that is, file data. With the growth of these massive file data, its data backup has also become a difficult problem. [0003] The traditional mass file backup and recovery method first needs to perform a complete backup, pack all the files to be backed up into a compressed file, and save the backup file metadata information (source location, source ...
