text: (cid:2) FlashCopy licensing is based on the virtual capacity of the source volumes. 
  
  (cid:2) Incremental FlashCopy copies all of the data when you first start FlashCopy, and then only 
  the changes when you stop and start FlashCopy mapping again. Incremental FlashCopy 
  can substantially reduce the time that is required to re-create an independent image. 
  
  (cid:2) Reverse FlashCopy enables FlashCopy targets to become restore points for the source 
  without breaking the FlashCopy relationship, and without having to wait for the original 
  copy operation to complete. 
  
  (cid:2) The size of the source and target volumes cannot be altered (increased or decreased) 
  while a FlashCopy mapping is defined.
