Fault tolerance strategies

Fault tolerance refers to the ability of a system to continue to function when part of the system fails. To create a fault-tolerant system, use preventive measures to minimize the possibility of a system failure and to minimize the impact of any disaster.

You can use the following strategies to improve the fault tolerance of your Client Security deployment:

• Minimizing single points of failure
  
  
• Using SQL Server log shipping
  
  
• Using RAID configurations
  
  
• Using power backup
  
  

This section provides more information about each of these strategies. You can apply these strategies individually or in combination. Because each strategy has a cost associated with it, it is important to examine the cost/benefit ratio for each before implementing it.
