Abstract: Temporarily limiting access to a storage device, including: determining that a storage device of a plurality of storage devices in a storage system is operating outside of a defined performance range; determining that the storage device operating outside of the defined performance range may be caused by a rehabilitative action performed on the storage device; and modifying a storage operation issuance policy for one or more storage devices of the plurality of storage devices until a determination that the storage device is operating within the defined performance range.

Abstract: An illustrative method includes a data protection system detecting a request provided by a source to perform an operation with respect to a storage system, the request including a logical address that comprises a logical element representative of a storage location within the storage system, determining whether the logical address further comprises an authorization element indicating that the source is authorized to initiate operations with respect to the storage system, and performing, based on the determining whether the logical address includes the authorization element, an action with respect to the operation.

Abstract: Data resiliency in a cloud-based storage system, including: receiving, for storage within a first tier of cloud storage of the cloud-based storage system, one or more segments of data; generating, for each of one or more shards of data of the one or more segments of data, self-describing information for recoverability of the one or more shards of data; and storing, within a second tier of cloud storage of the cloud-based storage system, both the one or more shards of data and the generated self-describing information for recoverability of the one or more shards of data.

Abstract: A storage system performs data replication with a recovery point objective (RPO). The storage system replicates data at intervals through data transfers over a network. The storage system determines bandwidth of the network. The storage system determines the intervals for replicating the data, based on size of data transfers, network bandwidth, and the recovery point objective.

Abstract: An illustrative method includes a data protection system determining a first compressibility metric associated with write traffic processed by a storage system, the first compressibility metric indicating an amount of storage space saved if the write traffic is compressed; determining a second compressibility metric associated with read traffic processed by a storage system, the second compressibility metric indicating an amount of storage space saved if the read traffic is compressed; determining, based on a comparison of the first compressibility metric with the second compressibility metric, that the write traffic is less compressible than the read traffic; determining, based on the write traffic being less compressible than the read traffic, that the storage system is possibly being targeted by a security threat; and performing, based on the determining that the storage system is possibly being targeted by the security threat, a remedial action with respect to the storage system.

Abstract: An illustrative method includes a data protection system identifying one or more attributes of a storage element within a storage system, determining, based on the one or more attributes of the storage element, a data protection policy for a dataset associated with the storage system, and applying the data protection policy to the dataset.

Abstract: A system including embedded storage devices is described. A method of system operation includes determining, by a processing device of a storage system controller operatively coupled via a network to embedded storage devices, that data is to be stored in a first storage portion of a first storage device of the embedded storage devices. The method also includes buffering the data in a second storage portion of a second embedded storage device of the embedded storage devices.

Abstract: Declarative provisioning of storage, including: identifying one or more policies associated with a storage object; determining, in dependence upon at least the one or more policies, a storage configuration for the storage object; and provisioning, in accordance with the storage configuration, storage that implements the storage object.

Abstract: Mediating between storage systems synchronously replicating a dataset, including: requesting, by a first storage system in response to detecting a triggering event, a lock for a shared resource from a mediation service; requesting, by a second storage system in response to detecting the triggering event, the lock for the shared resource from the mediation service; and responsive to acquiring the lock from the mediation service, the first storage system, instead of the second storage system, processing data storage requests directed to the dataset that is synchronously replicated across the first storage system and the second storage system.

Abstract: An illustrative method includes a data protection system determining a metric associated with operations performed with respect to a storage system during a measurement interval, determining that the metric deviates by more than a threshold amount from a historical baseline metric associated with the storage system, and directing, based on the determining that the metric deviates by more than the threshold amount from the historical baseline metric, the storage system to generate a recovery dataset for data maintained by the storage system.
