The high cost of failures on the network

Starting with Exchange 2007, Microsoft has offered a set of new tools for maintaining the messaging environment during disasters or equipment outages by replicating the Exchange implementation across a wide-area network. Although the tools are valuable, restoring a failed implementation can still be costly and time-consuming, according to a study from Teneros.

Cause of outage:     Work hours to recover:  Basic cost of recovery*:
Server failure

25 to 71

 $3,750 to $10,650

Database failure

26 to 75 

$3,900 to $11,250

Total site failure

26 to 75

$13,800 to $35,700

*Based on a rate of $150 per hour.
