Final answer:
A Storage Area Network (SAN) would provide the most security and control for automatically backing up data for a large company due to its dedicated environment, centralized management, and high performance.
Step-by-step explanation:
If you have a large company and are looking to ensure that your employees' work is backed up regularly with the most security and control, the best network to utilize would be a Storage Area Network (SAN). A SAN is specifically designed to handle large amounts of data storage, offering a robust and dedicated network environment that excels in data backup and disaster recovery processes. It operates on its own network of storage devices, separate from the LAN or WAN, which allows for better performance, scalability, and security. By using a SAN, you gain centralized management over backups, and can easily implement automatic backup schedules, reduce network congestion and improve backup speeds compared to a typical LAN or WAN setup.
