Default Delete all you like, but it won't free up space ; You've been (de)duped ...

From http://www.theregister.co.uk/2011/02..._reclaimation/

Quote:
Comment: Networker blog author Preston de Guise has pointed out a simple and inescapable fact: deleting files on a deduplicated storage volume may not free up any space.

De Guise points out that, in un-deduplicated storage: "There is a 1:1 mapping between amount of data deleted and amount of space reclaimed." Also, space reclamation is near-instantaneous. With deduplication neither need be true.
