What is Cloud Backup?

Quick answer

Copying data from computers, servers, or applications to storage run by a cloud provider so it can be restored if the original is lost.

Cloud Backup, explained

Cloud backup services automatically copy files, databases, or entire systems to remote data centers on a schedule. Because the copies are stored off-site, they protect against local problems such as theft, fire, hardware failure, and many ransomware attacks.

A widely used guideline is the 3-2-1 rule: keep three copies of important data, on two different types of storage, with one copy off-site. For a small business, that might mean files on office computers, a local backup drive, and a cloud backup. Software-as-a-service tools such as email and document platforms may also need separate backups, since providers' built-in retention is often limited. The most important step is testing restores regularly, because a backup that cannot be restored offers no protection.
