Technical Specification

Description

CallbackFilter is a software development kit, which tracks any file updates and backs up modified files on-the-fly. Your application gets notification when a file operation is executed. Besides simple notifications, CallbackFilter lets your application decide how to process a request: whether modify input or output data before or after the request is performed, deny or even cancel the request.

CallbackFilter consists of the system-level driver and user-mode API.

Driver

File System Filter driver intercepts various requests going to the file system. If the request matches one of the rules, specified by the application, the driver performs the action defined by the rule. The action can be to process or decline the request unconditionally and to call the callback function in your application synchronously or asynchronously. Your callback can also decline or allow the request, perform the request itself (not passing it further) or post-process the request.

User-mode API

User-mode API is simple and introduces about ten functions, specific to driver management and storage mounting operations. Also the API includes about 20 callback functions (events) which your application can handle to get notified about different types of file system requests.
The API is used to activate the filter and to set the callback rules.
