In an image-data managing apparatus for a work-flow system, wherein image data transmitted from a server are updated sequentially by a plurality of clients, a temporary storage for temporarily storing data being updated is provided in each client, and an image database, an image-data storage device, a work-flow managing unit, and a recovery-state managing unit are provided in the server. When a failure occurs in the image-data managing apparatus and the recovery of image data is requested, the recovery-state managing unit extracts control information from the work-flow managing unit, which control information indicates whether or not image data are preserved in the temporary storage or the image-data storage device in the course of update processing, thereby executing a function for identifying image data to be retrieved
