I wouldn’t necessarily trust a cloud so I would encrypt my files before uploading and wouldn’t use the cloud as my only solution. Because they guarantee for nothing and could just delete your account or their service. But it can expand your backup with another layer.
(Haven’t found my perfect solution, just some thoughts)
What do you use to backup all your photos and documents, cloud or external drive or both?
I never want to lose photos I’ve taken over the years. What’s the best solution to make sure they’re saved?
