Abstract

The embodiment of the invention provides a multi-user data sharing method and system, electronic equipment and a storage medium, the system comprises N upper-layer file systems, the ith user has read-write authority to the ith upper-layer file system, 1 < = N, 1 < = i < = N; a lower-layer file system, wherein each user has a read-only permission to the lower-layer file system; the i-th upper-layer file system and the i-th lower-layer file system corresponding to the i-th user are mounted on the i-th combined mounting file system; wherein if a data reading instruction is received, preferentially accessing the ith upper-layer file system; and if a data writing instruction corresponding to the lower-layer file system is received, storing data corresponding to the data writing instruction in the ith upper-layer file system. In the embodiment of the invention, the same copy does not need to be copied in the storage space of each user, so that the storage space of the user is saved, and the access of other users to the shared data is not influenced.

Description

technical field [0001] The present application relates to the field of electronic technology, and in particular to a multi-user data sharing method, system, electronic equipment and storage medium. Background technique [0002] In some application scenarios, multiple users need to share data. For the shared data, the access permission of the data needs to be set as read-only, otherwise user permission and data security problems will arise. If a certain user needs to modify the shared data, he needs to copy the shared data to his own storage space and modify the shared data in his own storage space. In this manner, the modified shared data will not affect other users' access to the shared data, which ensures user rights and data security. [0003] However, the above method needs to duplicate the same copy in the storage space of each user, which occupies more user storage space. Contents of the invention [0004] In view of this, the present application provides a multi-...
