Cloud backup solutions store backups of data in off-premise, geographically dispersed cloud-based data centres. Cloud backup is an “off-premise” solution, which is important to have in case of a local disaster. For example, if there is a fire in a building, that will destroy the original data. If the backed-up data is also in the building (“on-premise” backup), it will be destroyed too. In this case, the backup will not be effective. Therefore, it is important to back up to multiple locations, including a dispersed cloud backup solution.
