Abstract: Provided are a computer program product, system, and method for recording backup information for backed-up data items in a data item list. In response to a backup operation of a data set, information is obtained of backed-up data items in the backup operation. Data item entries are maintained for the backed-up data items in a data item list of the backup information for the data set. A determination is made of the backed-up data items corresponding to the data item entries in the data item list. Status lists are added for the entries in the data item list including backed-up status flags having backup information on the backup operations for the backed-up data items corresponding to the data item entries in the data item list.
