As others have said, I don't trust the cloud! I feel that everything on my computer is open to them. I put every photo on an external hard drive and even that failed once. I suppose that I need a second one for backup.
I view cloud backup as a fourth level system.
My primary backup is a hard drive connected to my computer.
My secondary backup is a hard drive stored in the house, but as far away from the computer as I can reasonably put it.
My tertiary backup is a hard drive stored somewhere else in town (I had a barn about a mile away).
My quaternary backup is on the cloud.
The primary, secondary, and tertiary backups are occasionally synchronized and rotated.
If my primary backup fails or my computer catches on fire I have my secondary backup. If the secondary backup also fails or if the computer (or something else) burns down the whole house I have my tertiary backup. If I had lived in Paradise, CA last year, my tertiary backup would also have been destroyed by fire.
Hard drives fail. I try to avoid that by (1) redundancy -- having 3 hard drives for backup and (2) a cloud system. To keep my backups viable takes maintenance. I have to keep the drives running occasionaly to exercise them so the bearings don't lock up. I have to occasionally verify the data so it doesn't get corrupted without my noticing. I have to replace the drives occasionally to avoid age related failures.
The advantage of the cloud storage is that someone else takes care of the maintenance. They hire people who are skilled at it and use components that are reliable, redundant, and distributed. I view cloud storage as being much more reliable than local storage.
Having said that, I should point out that I view local storage as MUCH more convenient than cloud storage. If I have a problem and have to restore a large block of data, I can do it from local sources in a few minutes or hours. Restoring a few Terabytes of data from the cloud will take me a few days or weeks.
The question is then, is the convenience or the reliability more important to you?
