What would happen if your primary server fails? What is the cost of downtime to your organization?

Mirrored servers can be used to lighten server loads and to provide redundant to network data.  In the event that the primary server fails, the secondary or mirror server continues to operate and to provide network user's access to their network data.

In a LAN environment, DFS keeps your network running in the event of a file server failure by providing a redundant link to your shared network files. Two or more servers can mirror each other's data.  Mirrored servers can also load balance data files. In a busy network environment, a request for a file can be alternatively passed to server 1 to server 2. By sharing the workload between two servers, access to network data is performed more quickly.

In a WAN environment, data mirroring provides quick access to network files spread across multiple locations. By replicating files on two or more servers, users can access files locally rather than on a remote server.
