Chapter 11. Advanced Copy Services 477
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 change is not recommended for the following 
reasons: 
– For example, 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.
– As another example, 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 Cleaning Rate options, see 
Table 11-1 on page 448 or see Table 11-5 on page 457.
When your FlashCopy mapping setup is ready, click Next.
3. You can choose whether to add the mappings to a Consistency Group, as shown in 
Figure 11-29. 
If you want to include this FlashCopy mapping in a Consistency Group, select Yes, add 
the mappings to a consistency group, and select the Consistency Group from the 
drop-down menu.

4. It is possible to add a FlashCopy mapping to a consistency group or to remove a 
FlashCopy mapping from a consistency group after they are created. If you do not know 
what to do at this stage, you can change it later. Click Next.
