  • Publication number: 20170097769
    Abstract: Systems and methods can implement one or more intelligent caching algorithms that reduce wear on the SSD and/or to improve caching performance. Such algorithms can improve storage utilization and I/O efficiency by taking into account the write-wearing limitations of the SSD. Accordingly, the systems and methods can cache to the SSD while avoiding writing too frequently to the SSD to increase or attempt to increase the lifespan of the SSD. The systems and methods may, for instance, write data to the SSD once that data has been read from the hard disk or memory multiple times to avoid or attempt to avoid writing data that has been read only once. The systems and methods may also write large chunks of data to the SSD at once instead of a single unit of data at a time. Further, the systems and methods can write to the SSD in a circular fashion.

  • Publication number: 20170083517
    Abstract: A data storage management system incorporates image recognition and classification features. The illustrative system generates thumbnail images to represent images detected in secondary copies. Subsequent image recognition and classification operations are based on the thumbnail images without need to access the secondary copies from which the thumbnails were derived. The system indexes thumbnail images and respective relationships to each other and to the source secondary copies. Metadata from the source secondary copies is extracted and preserved with the thumbnails. Thumbnail images, metadata, and related index data (collectively “thumbnail data”) are stored locally in an illustrative content index server, or in an enhanced storage manager, thus improving performance without interfering with ongoing storage management operations. Features are disclosed for searching within the system and performing storage management operations based on image criteria. Access to/from other systems is also possible, e.g.

  • Patent number: 9575673
    Abstract: An illustrative pseudo-file-system driver uses deduplication functionality and resources in a storage management system to provide an application and/or a virtual machine with access to a locally-stored file system. From the perspective of the application/virtual machine, the file system appears to be of virtually unlimited capacity. The pseudo-file-system driver instantiates the file system in primary storage, e.g., configured on a local disk. The application/virtual machine requires no configured settings or limits for the file system's storage capacity, and may thus treat the file system as “infinite.” The pseudo-file-system driver intercepts write requests and may use the deduplication infrastructure in the storage management system to offload excess data from local primary storage to deduplicated secondary storage, based on a deduplication database.

  • Publication number: 20170031707
    Abstract: The data storage system according to certain aspects can manage the archiving of virtual machines to (and restoring of virtual machines from) secondary storage. The system may archive virtual machines (VMs) that are determined to have a low level of utilization. The system may create a virtual machine placeholder for an archived VM, which may be a “light” or minimal version of the VM that acts like the actual VM. By using a VM placeholder, a VM may appear to be active and selectable by the user. When the user selects the VM, the VM placeholder can interact with the user in similar manner as the VM. Accessing the VM placeholder may trigger restore of the archived VM from secondary storage. The restore of the archived VM may be “seamless” to the user since the VM remains available while it is being restored.

  • Publication number: 20160334995
    Abstract: A data storage system includes a generic snapshot interface, allowing for integration with a wide variety of snapshot-capable storage devices. The generic interface can be a programming interface (e.g., an application programming interface [API]). Using the snapshot interface, storage device vendors can integrate their particular snapshot technology with the data storage system. For instance, the data storage system can access a shared library of functions (e.g., a dynamically linked library [DLL]) provided by the vendor (or another by appropriate entity) and that complies with the specifications of the common programming interface. And by invoking the appropriate functions in the library, the data storage system implements the snapshot operation on the storage device.

  • Patent number: 9495404
    Abstract: A data storage system protects virtual machines using block-level backup operations and restores the data at a file level. The system accesses the virtual machine file information from the file allocation table of the host system underlying the virtualization layer. A file index associates this virtual machine file information with the related protected blocks in a secondary storage device during the block-level backup. Using the file index, the system can identify the specific blocks in the secondary storage device associated with a selected restore file. As a result, file level granularity for restore operations is possible for virtual machine data protected by block-level backup operations without restoring more than the selected file blocks from the block-level backup data.

  • Publication number: 20160154709
    Abstract: The present enhancement leaves production systems undisturbed while a remote application (“testbed application”) executes elsewhere (“testbed host”). An intermediary computing device hosts an enhanced pseudo-disk driver, pseudo-disks, and an enhanced media agent. The enhanced pseudo-disk driver creates the pseudo-disks, each one representing an associated point-in-time backup image residing in secondary storage. A network, e.g., an Internet Protocol (IP) network or a Fibre Channel (FC) Storage Area Network (SAN), connects the intermediary device with the testbed host, and the enhanced media agent exposes pseudo-disks over the network using iSCSI or FC protocol, respectively. The testbed application uses an exposed pseudo-disk as its recovery data source, such that pseudo-disk resources provide data on an as-needed basis sufficient for the testbed application to operate, yet (a) without restoring the entire associated backup image from secondary storage and (b) without impacting the production environment.
