iCloud Drive is an in-built system on iOS devices where files and documents made on your machine can be backed up onto an online storage service.
This online storage can then be accessed through any web-browser to allow you to maintain a secure and accessible file storage system, safeguarding your work in the case where your device is no longer behaving as expected or is inaccessible
To enable your iCloud Drive, please complete the following:
- Open Settings app.
- Select your Apple ID (from the left-pane) and then select iCloud.
- Scroll down and enable iCloud Drive
Once your iCloud Drive has been enabled you can then move files saved in your apps to iCloud, from within the app the document is saved in, or in the files app.
