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.
What you need to know.
The server is usually hosted by a third-party service provider, who charges the backup customer a fee based on capacity, bandwith or number of users. In the enterprise, the off-site server might be proprietary, but the chargeback method would be similar.
