Backing up files to the cloud is an example of infrastructure as a service (laaS), a service of cloud com- puting which allows users to access and store files online. Cloud backup providers offer continuous backup of new and changed files, transmitting them over a secure Internet connection. Like many cloud services, they offer a "pay as you go" pricing model, where customers subscribe to a service for a period, and pay for the fea- tures or storage they use. Many cloud backup providers offer web and mobile apps to access and restore files. Cloud backup services differ from cloud storage services. Cloud backup services offer the software and infrastructure to back up and restore files only. They generally do not support synchronizing files across devices or sharing files with many users, which are common features of cloud storage services.
