I've kept a local HDD plugged in to my mini for several years now and Time Machine keeps everything backed up throughout the day. But I also have a pretty large iCloud Drive. I have all my documents, photos, and my important folders/files synced to it. With that, do I still need to do a backup locally? If I remember correctly, when I swapped out my internal HDD for an SSD, I loaded macOS and downloaded everything from the cloud. So other than wanting to find a file I accidentally deleted through Time Machine, what else am I missing?
