As an administrator, one of your concerns will be the impact of DPM data transfer operations on system and network resources. The primary data transfer operations are:

• Replica creation. This occurs once for each protection group member.
  
  
• Change tracking. This is a continuous process on each protected computer.
  
  
• Synchronization. This occurs on a regular schedule.
  
  
• Consistency check. This occurs when a replica becomes inconsistent.
  
  
• Express full backups. This occurs on a regular schedule.
  
  
• Back up to tape. This occurs on a regular schedule.
  
  

Understanding these operations and DPM processes will help you establish reasonable expectations for DPM performance.
