A file version control system and method thereof

Abstract

The invention discloses a file version control system, which includes a local library and a control module. The local library includes a work area, a metadata database, and a version library. The work area is used to store files managed by the system. For storing file trees, version trees, and version lists, the version library is used to store version files in the work area; the control module includes an abstract file system interface module, a file operation module, a metadata access module, a recovery manager module, a work Area monitor module; the invention encrypts files and backs them up to the server, which can prevent privacy leaks at the server side; automatically maintains version information of files, making it convenient for users to recover to file history versions after misoperation of files. In addition, the file tree, version tree, and version list are stored in a table, and then the table is converted into a key-value pair and stored in a disk file. The modification and deletion of cells in the table are implemented by writing new values, which avoids random access to the disk. Reduce disk I / O and reduce network overhead.

Description

technical field [0001] The invention belongs to the technical field of computer network applications, and in particular relates to a method for version control and encrypted remote backup of files. Background technique [0002] With the development of network technology, many network companies distribute part of the hard disk or hard disk array capacity of their servers to registered users, that is, the advent of network hard disks (network disks). Reliable and other advantages, so it has been favored by more and more users. [0003] However, the clients provided by network disk providers access files in plain text, and file security is increasingly becoming the primary concern of users. On the one hand, most network disk providers do not provide version control functions. After the operation, the file cannot be restored to the state before the wrong operation; on the other hand, some network disk providers provide file historical version recovery services, and users cannot...

Problems solved by technology

[0003] However, the clients provided by network disk providers access files in plain text, and file security is increasingly becoming the primary concern of users. On the one hand, most network disk providers do not provide version control functions. After the operation, the file cannot be restored to the state before the misoperation; on the other hand, some network disk providers provide file history version recovery services, due to weak functions, users cannot customize the file version
