About FlexClone volumes


Data ONTAP provides the ability to clone FlexVol volumes, creating FlexClone volumes. The following list outlines some key facts about FlexClone volumes that you should know:

  • FlexClone volumes are a point-in-time, writable copy of the parent volume. Changes made to the parent volume after the FlexClone is created are not reflected in the FlexClone.
  • FlexClone volumes are fully functional volumes; you manage them on the Manage Volumes page, just as you do the parent volume.
  • FlexClone volumes always exist in the same aggregate as their parent volumes.
  • FlexClone volumes can themselves be cloned.
  • FlexClone volumes and their parent volumes share the same disk space for any data common to the FlexClone and parent. This means that creating a FlexClone is instantaneous and requires no additional disk space (until changes are made to the FlexClone or parent).
  • Because creating a FlexClone does not involve copying data, FlexClone creation is very fast.
  • FlexClone volumes are created with the same space guarantees as their parent.
