The invention discloses a data backup method, computer equipment and a storage medium, and the method comprises the steps: obtaining current modification data corresponding to a modification operation when the modification operation for a backup source object is detected; determining a backup time point corresponding to the latest historical backup; acquiring target change data of which the change time point is later than the backup time point from the plurality of historical change data; determining the data change amount of the backup source object according to the current change data and the target change data; and when the data change amount is greater than a first preset change amount, performing data backup on the backup source object. According to the embodiment of the invention, when the data change is detected, the data change amount from the last backup to the current time point is obtained, and whether data backup is carried out or not is determined according to the data change amount, so that the
