In the age when information is of the utmost value one has to take care of data backup. Right away we want to note the difference between cloud backup and cloud storage. Cloud storage serves as an extension of a hard drive sitting in data centers. Cloud backup contains multiple time-point versions of user data and the ability to restore it. This is handy in case one gets hacked or critically infected with malware. So we’d like to talk about cloud backup services for Mac. 

Apparently, the only native macOS option for backups is saving data to an external storage drive via Time Machine. Yet there is the ability to save files to iCloud which is close to cloud storage for various data types: photos, mail, contacts, Safari bookmarks, etc. iCloud works both on macOS and iOS, but for Macs it’s more of a storage and for iOS devices it is a backup option. 200GB for $3 monthly or 2TB for $10 could be of great help. To configure iCloud on your Mac, open System Preferences > iCloud.
