    摘要: Cloud-based storage services are provided for storing and/or sharing content across multiple devices, where the content is periodically synchronized between the devices and the storage service. Conventionally, if locally stored content is deleted from a device, the delete would be propagated to the storage service causing the content to not only be deleted from the storage service but from any other devices where the content was locally stored and synchronized with the storage service. Embodiments are directed to retainment of locally deleted content at the storage service to prevent accidental or nefarious deletions of locally stored content on a device from further causing the content to be deleted universally from the storage service and/or multiple other devices. For example, the storage service may be configured to receive content stored locally on the device, detect a deletion of the content on the device, and retain the content at the storage service.

    摘要: A system, computer-readable medium, and method are provided for tracking modeling of datasets. The method includes the steps of executing an exploration operation to generate a result and storing an entry in a database that correlates an exploration operation configuration for the exploration operation with at least one performance metric. Each performance metric in the at least one performance metric is a value used to evaluate the result. The exploration operation utilizes a machine learning algorithm to process the dataset, and the exploration operation may be executed using at least one node in a computing cluster.

    摘要: File system-awareness of ghosting performed by one or more tiering engines allows a file system to receive and store metadata indicating an identifier of the tiering engine ghosting the file extents and a storage location of the ghosted file extents for later use by the tiering engine. The file system is able to receive and process requests to read and write to a file having ghosted extents.
