"I’m no tech expert, but one of the main benefits of cloud storage is the ability to access files from anywhere, provided you have internet connection."

If you really want to play-safe then utilize the services of two organizations.
I back-up everything to a second hard-drive – but, just in case of fire, flood or whatever I use "OneDrive" for cloud-storage.
I just love the way you can setup how and what you want to "sync" automatically.
