Answer:
These feature include Sparse VDL and Block clone
Explanation:
First an ReFS(Resilient File System) is a file system designed by Microsoft to minimize the availability of data and to have an efficient scalability to large data set across diverse workloads
Note : efficiency can be defined as the rate at which work is performed relative to the total work and/or cost incurred.
While
scalability: can be defined as the ability of a system to fit in the needs of an increased workload by repeatedly applying a cost-effective strategy for extending a system’s capacity.
Block clone:
This feature accelerates copy operations, enabling quick, low-impact VM (Virtual Machine)checkpoint merge operations.
Sparse VDL:
This is a feature of ReFS that allows it to zero file rapidly thereby reducing the time it takes to create fixed VHDs(Virtual Hard Disks)
