Abstract
Embodiments relating to garbage collection for a deduplicated and compressed storage device are described. One embodiment provides for a computer implemented method including creating a multiple sets of Bloom filters distributed across a set of multiple computing device nodes. One set of Bloom filters stores differing ranges of fingerprints for data stored on deduplicated storage containers, while a second set of Bloom filters includes a set of fingerprints correlated with files in a file system directory structure. A set of live fingerprints is determined for live fingerprints and storage segments associated with those fingerprints are copied to new storage containers.
