Sierra boasts a new feature called iCloud Documents an Desktop, which 
synchronises all the files on your Desktop and your Documents Folder (there’s 
no choice here) to iCloud, the idea being that all of those files become 
available to all of your other devices. It is turned on by default in a new 
Sierra installation, s when you first run Sierra it copies all of yourt 
candidate files up to iCloud Drive and deletes them from your computer. Fine if 
you have less that 5Gb of files, and you don’t use iCloud Drive for anything 
else. My documents Folder contains well over 700Gb of files created over many 
years of activity, so I was very careful to make sure I turned this feature off 
before running Sierra for the first time.

There are quite a few articles out on the web which deal with the position in 
which you now find yourself, Just a couple can be found at

First thing to do, therefore, is to turn iCloud Drive back on, and you will 
find all your documents in place is specific folders. The above articles 
contain tips on how to restore things to the way they were. You will then be 
able to turn iCloud Documents and Desktop off and never bother it again.

Following a clean install of Sierra (which is essentiall wehat you have) you 
cam use Migration Assistant (in /Applications/Utilities) to "restore from a 
Time Machine Disk”. This will bring everything back painlessly, but in your new 
Sierra environment (ie, you won’t revert to the previous OS).
