text: **11.1.19 Interoperation with Metro Mirror and Global Mirror**
  
  A volume can be part of any copy relationship (FlashCopy, Metro Mirror, or Remote Mirror). 
  Therefore, FlashCopy can work with MM/GM to provide better protection of the data. 
  
  For example, you can perform a Metro Mirror copy to duplicate data from Site_A to Site_B, 
  and then perform a daily FlashCopy to back up the data to another location. 
  
  **Note:**A volume cannot be part of FlashCopy, Metro Mirror, or Remote Mirror if it is set to 
  Transparent Cloud Tiering function. 
  
  Table 11-7 on page 465 lists the supported combinations of FlashCopy and remote copy. In 
  the table,*remote copy*refers to Metro Mirror and Global Mirror.
