  • Patent number: 10860427
    Abstract: A cluster includes cluster shared volumes and nodes. A subset of the nodes are designated as being backup proxy nodes responsible for backing up the cluster shared volumes. The cluster shared volumes are divided into groups, each group having a number of cluster shared volumes that is less than a total number of cluster shared volumes in the cluster. Generation is initiated for a particular snapshot for a number of cluster shared volumes belonging to a particular group. The backup proxy nodes backup data from the particular cluster shared volumes belong to the particular group using the particular snapshot. After the backup, the steps initiating snapshot generation and backing up are repeated until each group of cluster shared volumes has been backed up.

  • Patent number: 10742735
    Abstract: An illustrative storage management appliance is interposed between client computing devices and one or more cloud storage resources. The appliance uses cloud storage resources in conjunction with a network attached storage device configured within the appliance to provide to the client computing devices seemingly unlimited network attached storage on respective network shares. The storage management appliance monitors data objects on the network shares and when a data object meets one or more criteria for archiving, the storage management appliance archives the data object to a cloud storage resource and replaces it with a stub and preview image on the network share. When access to the stub and/or preview image is detected, the storage management appliance restores the data object from the cloud storage resource. The criteria for archiving flexibly allow individual data objects to be archived to cloud storage without archiving frequently-accessed “neighboring” data objects on the same network share.

  • Patent number: 10664447
    Abstract: Expandable cache management dynamically manages cache storage for multiple network shares configured in a file server. Once a file is written to a directory or folder on a specially designated network share, such as one that is configured for “infinite backup,” an intermediary pre-backup copy of the file is created in an expandable cache in the file server that hosts the network share. On write operations, cache storage space can be dynamically expanded or freed up by pruning previously backed up data. This advantageously creates flexible storage caches in the file server for each network share, each cache managed independently of other like caches for other network shares on the same file server. On read operations, intermediary file storage in the expandable cache gives client computing devices speedy access to data targeted for backup, which is generally quicker than restoring files from backed up secondary copies.

  • Patent number: 9426218
    Abstract: A network connection is established between a virtual storage appliance (VSA) in a virtual machine and a storage server system. The virtual machine can run on a computing device remote to the storage server system. Access is provided to a second shared namespace of data at the VSA over the network connection. The second shared namespace is a policy defined subset of a first shared namespace of the storage server system. Data in the second shared namespace is accessible at the storage server system by at least one other computing device communicatively coupled to the storage server system. The data in the second shared namespace at the VSA is replicated to create a local copy at the computing device. Changes to the local copy are synchronized with the data in the second shared namespace at the storage sever system.

  • Patent number: 9251011
    Abstract: Various embodiments of systems and methods for performing backup operation in In-memory database systems are described herein. The method includes receiving a request to create a backup of a data set from a main memory of the system. In response to the request, the data set is configured as read-only and a data structure having meta-data information identifying the blocks of data in the main memory that form the data set is invoked. A snapshot of the data structure is created and the data set is enabled for manipulation. Further, the method involves receiving a request to modify a block of data and copying the requested data block to a free memory block in the main memory. The data structure is updated by replacing the meta-data identifying the requested original data block with meta-data identifying the free memory block which holds a copy of the requested data block.
