Synchronously negotiating an object's creation time including identifying, by a first storage system among the two or more storage systems, a request to store a second updated version of the object; detecting, by the first storage system, a communications disruption among the two or more storage systems; and establishing, in dependence upon a local clock of the first storage system and a latest observed creation time associated with the object, a creation time for the second updated version of the object.

Synchronously negotiating an object's creation time across two or more storage systems

A storage system stores objects in a bucket at a storage device of the storage system. Each of the objects has a corresponding version. A processing device generates a snapshot of the bucket. The snapshot captures the corresponding version of each of the objects at a time associated with the generation of the snapshot.

Bucket versioning snapshots

A method of operating an object-based storage system, practiced by the storage system, is provided. The method includes establishing a plurality of buckets for objects, in the storage system and establishing a plurality of bucket views in the storage system, each bucket view supporting access to objects of one of the plurality of buckets. The method includes accessing an object of a bucket through one of the plurality of bucket views.

Bucket views

An illustrative method includes an object retention management system establishing a retention policy for a bucket of an object-based storage system, detecting an operation that causes an object to be stored within the bucket, and applying, based on the detecting of the operation, the retention policy to the object, wherein the retention policy prevents the object from being deleted or overwritten for a predefined time duration and the retention policy cannot be modified or disabled for the bucket by a user.

Protection of objects in an object store from deletion or overwriting

A method of failure detection in a storage system is performed by the storage system. The method includes detecting a failure in a nonvolatile random access memory device that is in or coupled to a storage device having storage memory. The storage system has multiple NVRAM devices and multiple storage devices that have storage memory. The method includes taking a portion or all of the NVRAM device offline. Taking a portion or all of the NVRAM device offline is responsive to detecting the failure. Taking a portion or all of the NVRAM device off-line is while keeping online the storage memory of the storage device, sufficient ones of the NVRAM devices, and sufficient ones of the storage devices to provide reliable access to data and metadata in the storage system.
