Abstract
A storage stack delete notification can be received at a storage stack filter. The delete notification can indicate deletion of primary data in a primary storage region. Secondary data that is taking up storage resources managed by the storage stack filter can be identified. The secondary data can be associated with the primary storage region, and the storage resources can be resources other than the primary storage region. It can be determined whether it is useful to have the secondary data continue taking up the storage resources. If having the secondary data continue taking up the storage resources is not useful, then the storage resources can be freed.
