Cloud Backup

Cloud Backup

Cloud backup, also known as online backup, is a strategy for backing up data that involves sending a copy of the data over a proprietary or public network to an off-site server. The server is usually hosted by a third-party service provider, who charges the backup customer a fee based on capacity, bandwidth or number of users. Online backup systems are typically built around a client software application that runs on a schedule determined by the level of service the customer has purchased. If the customer has contracted for daily backups, for instance, then the application collects, compresses, encrypts and transfers data to the service provider's servers every 24 hours. To reduce the amount of bandwidth consumed and the time it takes to transfer files, the service provider might only provide incremental backups after the initial full backup.
