  Repeat this step to create other mappings. To remove a mapping that was created, click 
  . Click**Next.**
  
  **Important:**The source and target volumes must be of equal size. Therefore, only the 
  targets with the appropriate size are shown for a source volume. 
  
  Volumes that are target volumes in another FlashCopy mapping cannot be the target of 
  a new FlashCopy mapping. Therefore, they do not appear in the list.

  In the next window, select one FlashCopy preset. The GUI provides the following presets 
  to simplify common FlashCopy operations, as shown in Figure 11-42 on page 485. For 
  more information about the presets, see 11.2.1, “FlashCopy presets” on page 466: 
  
  – Snapshot: Creates a point-in-time snapshot copy of the source volume. 
  
  – Clone: Creates a point-in-time replica of the source volume. 
  
  – Backup: Creates an incremental FlashCopy mapping that can be used to recover data 
  or objects if the system experiences data loss. These backups can be copied multiple 
  times from source and target volumes.
