What is the cheapest cloud backup?
It depends on your data size. Above ~2TB, unlimited plans (Backblaze, Carbonite) win on cost per terabyte. For a few hundred GB, a small capped plan (pCloud, Icedrive, IDrive) is cheaper. Slide your size above to see the winner.
Backup vs storage, what is the difference?
Backup (Backblaze, Carbonite, IDrive, Acronis) auto-copies your whole machine for recovery, often unlimited for one device. Storage (Google One, OneDrive, Dropbox, pCloud) syncs selected files and is capped. Many use storage for backup, so both are listed with a type label.
Are unlimited plans truly unlimited?
Mostly, but they usually cover one computer, back up only internal and attached drives, and may purge files a while after you delete them locally. They shine once you store more than about 2TB.
