Cloud backup is a service where data is copied and stored on remote servers hosted on the internet, rather than on local physical drives. This process ensures that critical information is safeguarded against loss, corruption, or disasters. Cloud backup solutions automatically synchronize and back up data at regular intervals, providing easy recovery options in case of data loss. These services offer scalability, allowing businesses to increase storage capacity as needed, and include features like data encryption and access controls to ensure the security and confidentiality of the backed-up information.
