Depends on what you mean by "restore point" here. If you mean a restore point like in Windows that you could use to restore all data after a crash, I have no idea.
But if you mean just to restore all of your pages to just the way you have it set up as far as wallpaper, arrangement of widgets and apps, the YES, there is a way. I back mine up often if I change or tweak something.
Go to menu>scenes. At the bottom should be a list of pre-made HTC scenes. At the top, make sure "Current (unsaved)" is selected, then press Save at the bottom and re-name if you wish (I left mine with the default that came up, "Custom1"). Once your current scene is saved, you can restore back to that set-up any time by going to menu>scenes, and then selecting your saved custom scene.
Once in a while I will change something and need to complete a new "restore point". I just repeat the above steps, again naming the scene "Custom1". Since CUSTOM1 already exists, it asks if I want to replace the old one. Select yes and now your new layout is saved.
Again, this only backs up your page layout options, not data. I hope this is what you are talking about, if not, sorry for wasting your time!
