  • Patent number: 9569321
    Abstract: A method for remote asynchronous volume replication and apparatus therefore are disclosed. Asynchronous replication is applied to deal with data changes on the source volume on the local site incurred by Host IO requests. In coordination with the “point-in-time differential backup” technology, the data is subjected to be backuped to Source BAS on the local site (backup-on-write operation) only when the original data being written into the block of the source volume is different from the data of the corresponding block of the destination volume on the remote site. As a result, once a new data is written into the source volume completely, the host will be responded that its Host IO request is completed. Therefore, the data necessarily transmitted to the destination volume on the remote site can be minimized, and the problem of remote data transmission limited by network bandwidth can be prevented effectively, thereby keeping the operation performance of the storage system at a better level.

An application layer is automatically restarted if the connection status is determined to be disconnected. Then, a step (b) is performed to determine whether the connection status is still disconnected after the application layer is automatically restarted. If the connection status is still disconnected after the application layer is automatically restarted, a network protocol layer is automatically restarted. Then, a step (c) is performed to determine whether the connection status is still disconnected after the network protocol layer is automatically restarted. If the connection status is still disconnected after the network protocol layer is automatically restarted, the network device is automatically rebooted.

  • Patent number: 9542281
    Abstract: Systems and methods herein obtain snapshots of one or more applications, while having minimal impact on performance of the applications. Embodiments may involve obtaining snapshots of modified application data within a node without disturbing the operations of the application. Systems may be configured to leverage the fast characteristics of local storage devices while utilizing the advantages provided by the remote storage of data. One or more applications may be preconfigured to record data modifications in one or more associated application state storages located on local memory. Further, one or more systems may operate in the background to identify modifications made to the associated application state storages and to determine an appropriate moment to take one or more snapshots of the stored data and transfer the one or more snapshots to one or more remote locations to be stored. Several factors may be used to determine when an appropriate moment has occurred.

  • Patent number: 9417968
    Abstract: Systems and methods enable a virtual machine, including applications executing thereon, to quickly start executing and servicing users based on pre-staged data blocks supplied from a backup copy in secondary storage. Substantially concurrently with the ongoing execution of the virtual machine, a virtual-machine-file-relocation operation moves data blocks from backup to a primary storage destination that becomes the virtual machine's primary data store after relocation completes. An enhanced data agent, operating in conjunction with an enhanced media agent in a storage management system, coordinates restoring the virtual machine and launching the relocation operation. The enhanced media agent pre-stages certain backed up data blocks based on predictive analysis pertaining to the virtual machine's operational profile. The enhanced media agent also pre-stages backed up data blocks for the relocation operation, based on the operation's relocation scheme.

    Abstract: An approach to multiprotocol ACL implementation with guaranteed protocol compliance is described. In one approach, a method of access rights validation for a multiprotocol supported file server is detailed. The method involves receiving a request to store a file with a security descriptor and storing the security descriptor in an extended attribute associated with the file. Subsequently, the security descriptor is expanded to extract a set of ACEs. Access to the file can then be validated against the ACEs expanded from the security descriptor according to the specifications of the protocol that created the security descriptor.

  • Patent number: 9329943
    Abstract: Techniques are disclosed for restoring a system volume on a computing system without requiring the system volume to be fully restored prior to being used or requiring the use of a dedicated recovery environment (e.g., the WinPE or BartPE environments). Instead, the computing system is booted directly from the restore image or by redirecting I/O interrupts to the restore image. That is, when user initiates a restore process, the system boots from the backup itself. Once booted, a background process can complete the restore process.
