  • Intelligent scheduling of backups
    Patent number: 11442817
    Abstract: Normal virtual machine operation is observed to automatically determine patterns of resource utilization. Backup activities are then scheduled, taking into account these utilization patterns. For example, if a normally scheduled backup would occur during a busy period, it may be rescheduled to a less busy period. As another example, backups made by made opportunistically during less busy periods even if not required by the normal backup schedule, in order to alleviate backup demands during more busy periods.

  • Automated development of recovery plans
    Patent number: 10901860
    Abstract: A system for validating a recovery plan for machines in a compute infrastructure is provided. In some examples, a system includes processors and a memory storing instructions that, when executed by at least one processor among the processors, cause the system to perform certain operations. The operations may include collecting statistics on network connections between machines in the compute infrastructure, based on the collected statistics, determining dependencies between the machines in the compute infrastructure, and identifying inconsistencies between the dependencies and an order of recovery for the machines specified in an existing recovery plan for the machines.

  • Integration of database with distributed storage system
    Patent number: 11841774
    Abstract: Techniques are described for determining whether a backup chain is within a recoverable range. The recoverable range defines a time interval in which data from a database system is recoverable to a point in time within the time interval. The backup chain is preserved while the backup chain is within the recoverable range. Upon determining that the backup chain is not within the recoverable range, operations are described for checking a retention policy for the backup chain, determining whether to preserve or expire the backup chain based on the retention policy, and preserving the backup chain based on that determination.

  • Automated review of source code for style issues
    Patent number: 10769046
    Abstract: In one aspect, a computer system automatically identifies style issues in a source code base. A reference set for a known style issue includes source code examples that exhibit the style issue. The source code examples in the reference set are compared to the source code base, for example using string convolution. Based on the comparison, locations in the source code base that are likely to exhibit the style issue are identified. Various steps in the processing may be implemented using machine learning models, clustering or other automated data science techniques.

  • CLUSTER-BASED NETWORK FILE SERVER
    Publication number: 20160127307
    Abstract: Methods and systems for managing, storing, and serving data within a virtualized environment are described. In some embodiments, a data management system may manage the extraction and storage of virtual machine snapshots, provide near instantaneous restoration of a virtual machine or one or more files located on the virtual machine, and enable secondary workloads to directly use the data management system as a primary storage target to read or modify past versions of data. The data management system may allow a virtual machine snapshot of a virtual machine stored within the system to be directly mounted to enable substantially instantaneous virtual machine recovery of the virtual machine.

  • Light-weight index deduplication and hierarchical snapshot replication
    Patent number: 11321278
    Abstract: A lightweight deduplication system can perform resource efficient data deduplication using an extent index and a content index. The extent index can store full fingerprints of data segments to be deduplicated and the content index can store shortened versions of the full fingerprints. The system can alternate between the extent and content indexes, and cache portions of the indices to perform lightweight data deduplication. Further, the system can be configured with an efficient heuristic approach for selecting content index data lookups for chains of volumes for deduplication, such as a long chain of snapshots.

  • Streaming database backup using cluster live mounts
    Patent number: 11182254
    Abstract: A database can be backed up and recovered by a cluster mapped to the database. Nodes of the cluster are mapped over channels to directories of the database. Scripts are generated from one or more templates that specify the order and values to be executed to perform a database job, such as database backup or recovery. To initiate a given database job, a template can be executed that generates and populates scripts, which are processed on the host of the database to perform the database job in a nearly instant manner using the mapped nodes of the cluster.

  • Managing files according to categories
    Patent number: 11232069
    Abstract: According to various embodiments, with respect to a target set of files being managed (e.g., protected by data snapshots), each file in the target set of files is classified into one of two or more filesets (discontiguous filesets), where each of these filesets comprises one or more files that are related to each other by one or more factors, such as frequency of file change or purpose of existence (e.g., used by a software application). Once classified, files within the target set of files can be uniquely processed by a data management operation (e.g., incremental data snapshot process) according to their association to a discontiguous fileset.
