DISTRIBUTED GARBAGE COLLECTION FOR DEDUPE FILE SYSTEM IN CLOUD STORAGE BUCKET

In one aspect, a computer-implemented method useful for Garbage Collection (GC) for a cloud storage bucket in a dedupe storage network including the step of providing dedupe storage network, wherein the dedupe storage network comprises a many-to-one replication network, a plurality of dedupe file systems that replicate dedupe data to a single storage bucket in a cloud-computing platform. The method includes the step of providing a cloud storage bucket. The cloud storage bucket comprises a set of dedupe chunks replicated from the plurality of dedupe file systems. With a remote GC thread, the method marks a set of expired dedupe images in the cloud storage bucket as expired. With a bucket GC thread, the method removes at least one garbage dedupe chunk from cloud storage bucket.
