A set of tracking records indicating a state of the application system is received. The set of tracking records is added to the active dump file. A storage signal for storing the active dump file into a backup device associated with the application system is generated according to a determination that a size of the active dump file meets a predetermined size threshold and according to a determination that a state of the inactive dump file is a ready state. The ready state indicates that the inactive dump file is available for storing another set of tracking records to be received in the future. Accordingly, two dump files may alternately store tracking records, and copies of the dump files may be continuously stored into a backup device to improve reliability. ## Claims ### Claim 1 A method for managing tracking records in an application system, the application system comprising an active dump file and an inactive dump file, the method comprising: receiving a set of tracking records indicating a state of the application system;
