Continuous Data Protection

CDP, also called continuous data protection, is different from traditional backup in that a schedule is not followed. Instead backups are constantly running. Restorations are specified to the point in time to which a user would like to recover allowing any point-in-time restoration. Traditional backups can only restore data to the point at which the backup was taken. We backup block-level differences in files (only the bits and bytes that change) rather than file-level differences thus minimizing the backup footprint. Traditional tape backup takes a copy of entire files.
