See HERE for info that MX-Linux has an app called Snapshot that will make an iso copy of an entire installed system. Timeshift can't do that.
Is there an app for Zorin that has a user-friendly GUI & will make an iso copy of one's complete system? (Please -- NOT Clonezilla.)

There's also Rescuezilla instead but I'm not sure if that's quite what you are looking for. Useful to know it exists though so have a look at it anyway.
That's what I use ..... much easier to use than Clonezilla for me ....
