Enterprises today create and maintain critical corporate data in a wide variety of locations, both inside the firewall of an internal network, and also outside the protection of the network on web servers, application servers and in remote offices. This white paper provides information on maintaining security levels and backing up data in the DMZ architectures through firewalls, and other data protection strategies, to give the IT Department a better understanding of backup and restore security. The security is not only a network configuration, but also a software philosophy to improve the computer enterprise policy.
