Thank you for the response R C-R. My best guess was that the 300 was seconds. A good guess, but it was only a guess. Affinity should be clear in the preference itself exactly what it is I am setting. Affinity is definitely autosaving the documents, but they are not making backups because an autosave is not a backup. Also, Affinity doesn't "suggest" that a complete, stand alone back is saved, they state precisely that in the help document. A backup of a computer file, or any file, is always a seperate copy or it isn't a backup. Wherever Affinity is saving these documents, if that area becomes corrupted, every document that I haven't specifically saved through use of the hamburger menu is history. And even if I saved those documents throught the hamburger menu, any changes I have made to those documents after that save are history because, there are no backups. I would suggest to Affinity that two things be done here: 1. Define the units used in the "Autosave Interval" preference so that anyone adjusting that preference knows exactly what they are setting. Preferably in minutes rather than seconds so no calculations are necessary. 2. Change the incorrect and misleading wording in the help document that attempts to explain what the "Autosave Interval" is, and does. Now, as far as the "Save Location" preference having nothing to do with the "Autosave Interval" preference, you are absolutely correct. And I don't think there is anything more counterintuitive than that.
