text: – Multitarget FlashCopy 
  
  IBM Storwize V7000 supports copying of up to 256 target volumes from a single source 
  volume. Each copy is managed by a unique mapping and in general, each mapping 
  acts independently and is not affected by other mappings sharing the source volume. 
  
  – Cascaded FlashCopy 
  
  This function is used to create copies of copies, and supports full, incremental, or 
  nocopy operations. 
  
  – Reverse FlashCopy 
  
  This function enables data from an earlier point-in-time copy to be restored with 
  minimal disruption to the host. 
  
  – FlashCopy nocopy with thin provisioning 
  
  This function provides a combination of using thin-provisioned volumes and FlashCopy 
  together to help reduce disk space requirements when making copies.
