Abstract: A cloud storage gateway device can be used to deduplicate data across different namespaces while complying with SLOs that govern data of the different namespaces. A cloud storage gateway device can use multiple fingerprint indexes to comply with different SLOs. Each fingerprint index corresponds to a different SLO. Thus, the cloud storage gateway device deduplicates data against other data governed by a same SLO. Assuming an SLO aligns or indicates a cloud storage target, the cloud storage gateway device will deduplicate data against other data that will eventually migrate from the device to a same cloud storage target. The cloud storage gateway device ensures satisfaction of the governing SLO(s) from receipt of data, through deduplication, to the migration of the data to a cloud storage target.

Abstract: A remote data storage system for providing one or more mobile devices with a remote data store. The system may include a cloud platform with a storage management application and a data store. A mobile storage application may operate on a mobile device to enable the mobile device to interact with the storage management application. The storage management application may condition data for exchange between the mobile device and the data store. The conditioning of data may include the replacement of duplicate data subsets with references to equivalent data subsets. Other embodiments are described and claimed.

Abstract: The present invention provides for an efficient method, apparatus, and system for updating file system information when shared memory contents are moved from one physical location in memory to another. Traditional file systems manage such memory movement at the granularity of physical memory blocks. However, it will often be the case that multiple blocks will be moved, and the present invention takes advantage of the fact that it is more efficient to process the shared memory movement of memory contents at the granularity of an extent. The invention employs a data structure, where each record in the data structure contains information about the shared memory extents of the file system.

Abstract: Various methods and systems can be used to provide standard file system access to data that is originally accessed only by a proprietary interface. One such method involves querying an application (e.g., a database management system) for information identifying a location of each of several data objects within several volumes. The application provides a proprietary interface to the data objects stored on the volumes. The method then creates metadata, which associates each of several files within a new file system with the location of a respective one of the data objects within the volumes. The metadata can be created by an in-place conversion module implemented on a computing device. The method then provides the application with access to the files within the new file system, subsequent to creating the metadata.

Abstract: Systems and methods for extent reference count updates are presented. In one embodiment; a reference count update method includes: receiving an indication of new reference association with an extent of a shared storage component; generating reference count update log information for a reference count update log to indicate the new reference association with an extent of a shared storage component, wherein the altering occurs inline; forwarding a successful data update indicator to initiator of activity triggering the new reference association with the extent of the shared storage component; and updating a reference count table in accordance with the information in the reference count update log, wherein the updating is included in a background process.
