About Online Backup

Online backup means using a network connection to back up data from a computer or hard drives to a remote server (that is the cloud storage service we generally mentioned). Online backup services usually provide a web-based management console to access data and monitor the running status of backups. The backed-up files will be encrypted and stored in the provider's data center. Individuals or businesses can directly download and use data backup or browse archived files from any computer or device.
