It is common to create one or more copies of production data for the purpose of generating reports, mining, and testing. These cases frequently update the copies of the data with the most current data, and one or more copies of the data always exists. FileSnaps can be used to create multiple copies instantly. The application that uses the original data can see a slight performance hit due to the unsharing of data that can take place during updates. This slight impact on performance can still be present even when all FileSnaps have been deleted. However, you rarely see all FileSnaps being deleted since these use cases usually have one or more copies at any given time.
