Cloud Storage and Syncronization.

Protect your Documents and Photos by syncronizing to the cloud. Syncronize your data, contacts and calendar between multiple computers and mobile devices. The difference between syncronization and backup is that if you delete a file, syncronization also deletes it (usually to a recycle bin), backup keeps the deleted file.

* Larger free storage and syncronization without moving your files, makes Google my recommendation.
Apple's iCloud and Microsoft's OneDrive move your files when setting up syncronization.
This breaks recent file links and is a major drawback.
