Does TimeMachine backup iCloud Drive files? Does TimeMachine backup the files I have in iCloud Drive? I want to use iCloud Drive more for files I don't use a lot. But it is important that there is a regular backup.
iCloud Drive is a folder located in the Library folder: ~/Library/MobileDocuments.

This folder will be back-upped but there are a few strings attached to it:


As long as the files are stored locally it will be backed up. 
When there is a cloud icon next to the file it means it's stored in the cloud and not longer locally. It will not been backed up.
