Cloud storage and online backup are similar, but each has distinct functions.
Cloud storage is primarily for keeping files that you access routinely and share with others.
Backup, on the other hand, is about long-term storage for the purpose of recovery in case of data loss. Backup services don’t usually have collaborative or file-sharing features. A great cloud backup provider is Backblaze that you can try for free for a year with an ExpressVPN subscription.
