Cloud backup is a service that allows individuals and organizations to securely save copies of their data to remote servers via the internet. This process ensures that important files, documents, and system information are protected from loss due to hardware failure, theft, accidental deletion, or disasters. By storing data offsite, cloud backup provides an easy way to restore information to devices if the original data is lost or damaged. Most cloud backup solutions offer automated, scheduled backups and encryption for enhanced security, making it a reliable and convenient option for safeguarding digital assets.
