Incremental (*INCR or *CUML) backups of spooled files are based on the creation date of the spooled files. Only spooled files that have a create date after the incremental backup reference date will be saved or putting it another way, only spooled files created after the last full save of the spooled files will be saved.
Incremental backups of spooled files can be performed when saving control groups with spooled file list (*SPL) entries.
