When selecting a preset, some options, such as Background Copy Rate , Incremental , and Delete mapping,  after completion are automatically changed or selected. You can still change the automatic settings, but this is not recommended for the following reasons: 

– If you select the Backup  preset but then clear Incremental  or select Delete mapping after completion , you lose the benefits of the incremental FlashCopy. You must copy the entire source volume each time you start the mapping. 

– If you select the Snapshot  preset but then change the Background Copy Rate , you have a full copy of your source volume. 

For more information about the Background Copy Rate and the Cleaning Rate, see Table 11-1 on page 473, or Table 11-5 on page 482. 

When your FlashCopy mapping setup is ready, click Next .
