A managed cloud backup service automates the backup process and scales the storage space as needed without manual intervention, which aligns with the organization's requirements for a flexible and secure backup solution tailored for a remote workforce. A dedicated cloud server, while secure and accessible, typically requires manual scaling of storage capacity. A company network drive, even though it might be accessible via VPN, doesn't offer the same level of scalability and Internet-based accessibility as a cloud service. Using physical drives for this purpose is impractical due to manual efforts needed to maintain and secure them.
