  • Patent number: 10949378
    Abstract: A checkpointing mechanism by which in-memory data structures are copied from computation nodes (200) to staging nodes (700) by using RDMA, checkpoints are made and kept in memory in the staging node (700), and then asynchronously copied to non-volatile storage (150). In contrast to previous approaches, checkpoints remain in volatile memory (740) as part of the checkpointing mechanism. As a result, recovery from checkpoint is potentially faster, since the required checkpoint may be already in memory (740) in the staging node (700). An automatic and customisable mechanism is provided to control when the checkpointing process is triggered. As an alternative to copying an object through the network, the object in memory can be updated to a newer version of the object by applying the chain of changes made in the object in the corresponding computation node (200).

  • Patent number: 10877928
    Abstract: An executable utility is injected into cloud-based virtual machines (VMs) that are subject to backups by a data storage management system tasked with protecting the cloud-based VMs and their associated data. The utility is injected into a target VM which is “live” and operating. The utility analyzes the VM's live volume to discover data extents therein, and for each extent computes a respective checksum and determines whether the extent is a “hole.” Afterwards, checksums help identify changed data in successive snapshots of the live volume, so that only changed data will be read and backed up in incremental backups. Time is saved in performing the backup operation first by pre-warming the backup's source volume in parallel with the utility analyzing the live volume, and second by skipping read operations for extents unchanged since a preceding backup. The resulting incremental backup operation is sped up as compared to prior art approaches.

  • Patent number: 10853192
    Abstract: Database performance may be improved by creating additional backups from an existing backup, rather than the original database or audit log source. A second backup may be created from a first backup by copying the files from the first backup to the second backup. The replication from a first backup to a second backup with modification of the file history information allows identical backups to exist on different types of storage devices, including virtual storage devices. Continue functionality may be implemented during a move function to restart replication at a new starting point while retaining the existing move set. Tape-type-override functionality may be implemented during the replication to replace the tape type for the backups with another compatible type while retaining the original type for history file entries, tape trailers, and messages.

  • Patent number: 10452680
    Abstract: Master-slave pairs can be used to provide data redundancy in an electronic data environment. A master peer can include a B-tree with references to the corresponding data. When provisioning a slave, the master can send a point-in-time copy of the B-tree to the slave, which can allocate the necessary space on local storage and update the references of the B-tree to point to the local storage for the slave. If the master and slave become disconnected, one of the peers can function as a solo master until the peers are again connected, at which point the old peer can be brought current or a new slave provisioned. A log peer can also be provisioned by a solo master, which can store data for operations received during the disconnect for use in catching up a slave peer, which could be the old slave, the log peer, or a new peer.

  • Patent number: 10061862
    Abstract: Methods and systems for creating a compact tree node representation of an XML document. One implementation commences by allocating memory for storing an XML tree index data structure, then allocating another separate portion of memory to store a hash table. Then, traversing an XML document to process the traversed nodes as follows: (a) when the traversed node is an element node, then adding the element node to the XML tree index data structure (b) when the traversed node is a text node, then populating a text node index into the XML tree index data structure and copying the text node values to the hash table, and (c) when the traversed node is an attribute node, then populating an attribute node index into the XML tree index data structure. Such a structure supports fast index-based tree restructuring, and permits very large XML document to be accessed within tight memory size constraints.

  • Patent number: 10055440
    Abstract: Partitioning of a source table of a database to a target table is initiated. Thereafter, a replay table is generated that is populated with triggers for database operations performed on the source table for subsequent replay for the target partitions. Data is later moved (e.g., asynchronously moved, etc.) from the source table to the target table. The database operations are replayed on the target table T subsequent to the moving of the data using the replay table. In addition, the source table is dropped when all of the data has been moved to the target table and there are no operations requiring replay. Related apparatus, systems, techniques and articles are also described.

  • Patent number: 10009220
    Abstract: An in-vehicle terminal and a mobile terminal receive a request and a first identifier for identifying the request and store the first identifier in a buffer, the mobile terminal sends the request to a server, which stores the first identifier in a buffer when the request includes the first identifier and generates a second identifier when the request does not include the first identifier. When an event occurs, the mobile terminal generates and stores a message and a message code related to the second identifier together with the second identifier, transfers a response including the first identifier, the message and the message code to the mobile terminal when the first identifier exists in the buffer, and transfers a response including the message and the message code to the mobile terminal when the first identifier does not exist in the buffer. The mobile terminal displays the message and the message code.

  • Patent number: 9953038
    Abstract: The efficient backing up of a hierarchical system in cloud blob storage. The hierarchical structure of the system as it existed at a prior instance in time is reconstructed. A change journal that represents changes in the file system that prior instant in time is then used to formulate an updated file system hierarchy as it exists at a second instant in time. An updated injected representation of the file system, and updated file system reversal information is then formulated and provided to cloud blob storage. The injected representation of the file system is a one-to-one function of the content of the file system, in that the reversal information can be used to recover the content of the file system. Injected representations of various nodes in the system hierarchy may also be remotely stored.

  • Patent number: 9916325
    Abstract: A method includes flushing a write transaction based on byte-ranges within a file system block. It is determined if the write transaction is a first write transaction to the file system block and whether to flush the received write transaction to a recovery log. If it is determined to flush the write transaction to the recovery log and the received write transaction is the first write transaction: the data associated with the write transaction is appended in the recovery log and byte-ranges remaining in the file system block are recorded, and also recording an associated particular bit value or particular bit pattern that the remaining byte-ranges must be set to before the remaining byte-ranges are accessed or when a recovery sequence for recovering data in the recovery log executes due to failure. The write transaction is replicated. The entire file system block byte-range is marked as committed.

  • Patent number: 9870151
    Abstract: Various techniques deduplicate common virtual disks during backups of virtual machines. For example, one method involves receiving a request to perform a backup operation to backup one or more virtual machine and then performing the backup operation in response to receiving the request. Performing the backup operation involves detecting whether a virtual disk associated with a virtual machine is already identified in a backup catalog for the backup operation, based upon a globally unique identifier associated with the virtual disk, and selecting to create a reference to a backup copy of the virtual disk instead of creating another copy of the virtual disk, if the backup catalog already identifies the virtual disk. Performing the backup operation can also involve accessing information identifying a hierarchy of virtual disks.
