I've tried signing out of iCloud (letting it delete all the synced info from my Mac) and signing back in…..
That's where I'm headed (without the signing back in) but I just want to be sure I can restore the deleted files either from my Time Machine or Super Duper backups.
The files can be restored, but they'll just be deleted again if you restore them to the same place they came from.
A better solution is to export or save your iCloud files to a different place on your hard drive (for example, Documents) before you sign out.
In my case, I need to have access to my iCloud documents on all my devices because I travel a lot and will update them from a number of different devices.
