摘要： A method for asynchronously replicating data onto a tape medium is implemented at one or more server computers associated with a distributed storage system and connected to a tape storage system. Upon receiving a first request from a client for storing an object within the tape storage system, a server computer stores the object within a staging sub-system of the distributed storage system and provides a first response to the requesting client. If a predefined condition is met, the server computer transfers objects from the staging sub-system to the tape storage system. For each transferred object, the server computer adds a reference to the object to a tape management sub-system, identifies a corresponding parent object associated with the object and its metadata within a parent object management sub-system of the distributed storage system, and updates the parent object's metadata to include the object's location within the tape storage system.

摘要： A system and method generating and distributing replica removal requests for objects in a distributed storage system is provided. Replica removal requests for objects in a distributed storage system are generated based at least in part on replication policies for the objects. A respective replica removal request instructs a respective instance of the distributed storage system to remove a respective replica of the respective object so as to at least partially satisfy replication policies for the respective object. Then the replica removal requests for the objects in the distributed storage system are distributed to respective instances of the distributed storage system corresponding to the replica removal requests for execution.

摘要： A server computer at a first storage sub-system of a distributed storage system receives from a client a first client request for an object. If the object is not present in the first storage sub-system, the server computer identifies a second storage sub-system of the distributed storage system as having a replica of the requested object, the requested object including content and metadata. The server computer submits an object replication request for the requested object to the second storage sub-system and independently receives the content and metadata of the requested object from the second storage sub-system. The server computer generates a new replica of the object at the first storage sub-system using the received metadata and content and returns the metadata of the new replica of the object to the client.

摘要： A system and method for generating replication requests for objects in a distributed storage system is provided. For a respective object in a distributed storage system the following is performed. Replication policies for the object that have not been satisfied are determined. Replication requests are ranked for the object whose replication policies have not been satisfied based on a number of replicas of the object that need to be created in order to satisfy the replication policies for the object. Replication requests are generated for the object based at least in part on the replication policies for the object that have not been satisfied and on a current state of the distributed storage system. At least a subset of the replication requests for the objects in the distributed storage system are distributed to respective instances of the distributed storage system corresponding to the replication requests for execution.

摘要： A distributed storage system has multiple instances. There is a plurality of local instances, and at least some of the local instances are at physically distinct geographic locations. Each local instance is configured to store data for a non-empty set of blobs in a plurality of data stores having a plurality of distinct data store types. In addition, each local instance stores metadata for the respective set of blobs in a metadata store distinct from the data stores. There is also a plurality of global instances. Each global instance is configured to store data for zero or more blobs in zero or more data stores and store metadata for all blobs stored at any local or global instance. The system selects one global instance to run a replication module that replicates blobs between instances according to blob policies.

摘要： A distributed storage system stores data for files. A first blob (binary large object) of data is received. The first blob is split into one or more first chunks of data. Content fingerprints for the first chunks of data are computed. The first chunks of data are stored in a chunk store while and their content fingerprints are stored in a store distinct from the chunk store. A second blob of data is received. The second blob is split into one or more second chunks of data. Content fingerprints for the second chunks of data are computed. Then for a second chunk of data whose content fingerprint matches a content fingerprint of a first chunk of data, a second reference to the corresponding first chunk of data that has a matching content fingerprint is stored, but the second chunk of data is not stored.
