Before you install and use CPS, you should consider the following questions to help assess your backup requirements:
- 
How much information can you store and which servers should store it?
 - 
Has the System Information for the server been modified so that it warrants backup protection?
 - 
What information is business-critical and needs to be backed up continuously (every time the information changes)?
 - 
What information you back up hourly, daily, weekly, monthly, or at irregular intervals?
 - 
What information should you back up on an as-needed (manual) basis only?
 - 
Are shared folders being used, or do all users have unique folders in which their files are stored?
 - 
Who should have access to the Continuous Protection Server Administration Console for the purpose of changing settings, scheduling backups, restoring information, and managing system alerts?
 - 
Who should have access to various backup destinations for the purpose of restoring data?
 - 
How often should data snapshots be captured and how many should be retained?
