I used this when I was working on a product that used automated tests to upload files repeatedly during the day. The volume of test files was so great that it continually put pressure on the storage -- more pressure than the uploads from the actual users. Fortunately the uploads were from a set of a few dozen static files, and de-duplicating the data via fdupes was able to drop disk usage by a factor of 20-50x.
