Abstract

Disclosed is a method of recovering a computer-implemented process, the process being computer code loaded into a working memory and processed by at least one processor. The process receiving signals that initiate internal procedures. The method having the steps of saving a state of the process by copying the data from the working memory allocated to the process, recording the signals input to the process since the saving of the state. When a command to recover the process is issued the process is restored to the saved state and the recorded signals applied to the restored process to complete the recovery process. The recorded signals may be filtered and /or reordered before being applied to the restored process.
