I never used my Time Machine backups since I started using it for my Mac in 2012 (two MacBook Air laptops ago). Today, I finally chose to wipe it fresh and stick with SuperDuper alone to free up that space on my external hard drive. (In other words, ditching the previous versions of files.) I’ll stick with a daily regimen of using Smart Update from this point forward.
