Explanation:
FlexClone is an ONTAP feature that allows you to instantly create writable virtual copies of data volumes, files, and LUNs, which do not consume storage space. A FlexClone volume, file, or LUN is a writable point-in-time image of the FlexVol volume or another FlexClone volume, file, or LUN. FlexClone is based on Snapshot technology, which captures a read-only image of a volume at a given point in time. FlexClone is perfect for DevOps and test environments, where multiple copies of a database are needed for testing or development purposes.
