An intercept engine is installed on a computer and includes an intercept filter adapted to intercept selected commands transmitted between a file system and a storage device. The intercept engine also includes an intercept manager adapted to transmit to the intercept filter one or more primitives, wherein each primitive includes device information specifying a device, wherein a command directed to the specified device is to be intercepted, command type information specifying a type of command to be intercepted, and follow-up action information specifying an action to be performed after the command has been intercepted. A primitive may also include default action information specifying an action to be performed with respect to the command if a communication between the intercept filter and the intercept manager is interrupted. The intercept engine intercepts commands transmitted between the file system and the storage device in accordance with the one or more primitives.
