Can I backup Microsoft Office for Mac documents to my iCloud Drive on my iMac? Can I backup to that drive, PDF files that I have stored in iBooks that were not purchased from iTunes? Thank You.
You can store all kinds of documents on iCloud drive, only don't use the specific Mac application folders for your third-party documents. Create your own folders.
But since you are asking about "backup": And you should be aware, that iCloud drive is meant to be your central storage for your working documents, that you want to access from all devices. iCloud Drive is not meant to be a backup. If the copy on iCloud Drive is your only copy, you have no backup. If you modify or delete a file on iCloud drive the change will sync to all devices and you will not be able to restore it without a backup.

With iCloud Drive, you can safely store all your presentations, spreadsheets, PDFs, images, and any other kind of document in iCloud. Documents you store in iCloud Drive will be kept up to date across all of your devices, and you can access them from your iPhone, iPad, iPod touch, Mac, or PC.
Here's what you can do with iCloud Drive:
- Store and access all of your documents in one place from any of your devices
- Keep files and folders up to date across all your devices
- Create new files and folders from iCloud-enabled apps
- Work on the same file across multiple apps
If you use Time Machine to backup your Mac, your iCloud Drive documents will also be included in the backup.
