GN4 distinguishes, by means of a workstate, the content to be archived from the content to be skipped.
You can define such workstates either as a parameter, assigned to a group or user, or by specifying it as a command line parameter. See Parameters for archiving for the list. See Assign parameters to groups or users for the procedure.
When all the prerequisites are met, on the pages navigator listing on the Pages main tab, select a page to archive, and then on the File menu, click Archive.
