The technology that allows for the automatic backup of files in the cloud is referred to as cloud backup or cloud sync. This technology involves using cloud storage services that continuously or periodically create backups of local files, ensuring data preservation and accessibility. Users often set preferences for backup frequency and the types of files to include. Solutions like Backblaze and Carbonite simplify data protection by securely storing backups off-site, reducing the risk of data loss due to hardware failures, theft, or disasters.
