How DPM Operations Affect Performance

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.
