A computer system is coupled to a database management system for managing data, and an infrastructure system for managing storage areas of the data. The computer system is configured to: receive a tracking request including identification information of target data; calculate, based on information on the data managed by the database management system, a data duration period of the target; identify, based on configuration history information on a configuration of the storage areas, a first storage area which is provided to the database management system for the data duration period and which stores the target data; and execute, based on the data duration period and history of copying operation of the storage areas of the infrastructure system, with the first storage area as an originating point, tracking processing for tracking a second storage area in which the target data is stored by the copying operation.
