Abstract
In a deduplicated microservices-based storage system and method running in a cloud includes frontend and backend microservice nodes that process requests from a plurality of clients and interface with a master node and one or more worker nodes connected as a network for deduplicating, storing and retrieving data from object storage, a worker node receives queries and fingerprints for data segments of a data similarity group to be deduplicated, obtains and returns the similarity group from its cache or from object storage using a key. The system compares the received fingerprints to stored fingerprints to determine non-duplicates for deduplication. The worker node updates similarity groups in its cache and in a write-ahead log with a reference to a compression region of non-duplicate segments, and periodically writes modified objects from its cache to object storage.
