Abstract
The invention provides a system and method for file synchronization. One embodiment of the system of this invention includes a software program stored on a computer readable medium. The software program can be executed by a computer processor to receive a file from a server; store the file as a cached file in a cache; determine if the cached file has been modified; and if the cached file has been modified, communicate the cached file directly to the database.
Claims26
A computer system comprising:
- a client computer processor;
- a client computer network connection device coupled to the processor and operable to connect to a network;
- a client computer memory coupled to the client computer processor the client memory having operating system space and user space;
- a client computer operating system having an operating system file management system;
- a user space cache manager in the client computer memory, the user space cache manager executable by the processor to perform operations comprising:
- communicating with a server over the network to download a copy of a file from a file repository;
- storing the downloaded copy of the file as a cached file in a local cache at the client computer, wherein the local cache comprises a location in a file system of the file management system;
- interfacing with the file management system of the client computer operating system to cause an automatic notification feature to provide the cache manager automatic notifications with respect to the local cache;
- in response to receiving an automatic notification with respect to the cache, determining if the cached the has been modified by another application;
- and
- when it has been determined that the cached file has been modified, sending changes to the cached file to the server to synchronize the file at the file repository with the cached file.
A computer program product comprising a non-transitory computer readable medium storing instructions, the stored instructions executable by a processor of a client computer having a client computer operating system with a file management system, the stored instructions executable by the processor to provide a cache manager that resides in user space of a client computer memory having user space and operating system space, wherein the cache manager residing in user space is configured to:
- communicate with a server over a network to download a copy of a file from a file repository to the client computer;
- store the downloaded copy of the file as a cached file in a local cache at the client computer, wherein the local cache comprises a location in a file system of the file management system;
- interface with the file management system of the client computer operating system to configure an automatic notification feature of the file management system to provide to provide the cache manager automatic notifications with respect to the local cache;
- in response to receiving an automatic notification with respect to the local cache, determine if the cached file has been modified in the local cache by another application;
- and
- based on a determination that the cached file has been modified in the local cache by another application, send changes to the cached file to the server to synchronize the file at the file repository with the cached file.
