  • Method and system for sharing pre-calculated fingerprints and data chunks amongst storage systems on a cloud local area network
    Patent number: 11113153
    Abstract: A method and system for sharing pre-calculated fingerprints and data chunks amongst storage systems on a cloud local area network. Specifically, the disclosed method and system extend the functionality of data deduplication storage systems to include querying other data deduplication storage systems on the cloud local area network for fingerprints, corresponding to data chunks, when these fingerprints and data chunks are not stored locally. The transfer of data chunks between one data deduplication storage system to another through the cloud local area network may be a faster and cheaper alternative to the transfer of data chunks between a data deduplication storage system and a client through a wide area network.

  • Leveraging a disaster recovery infrastructure to proactively manage cyber security threats to a production environment
    Patent number: 11100217
    Abstract: Described is a system that leverages an isolated disaster recovery (or testing) environment to manage a range of cyber security threats associated with a virtual machine. The system may proactively manage such security threats by creating a second instance (e.g. replica) of a production virtual machine and verifying potential configuration updates that may be applied to the virtual machine to manage such security threats. The configuration updates may be verified by performing various tests on the second instance of the virtual that executes within the secure and isolated environment. Accordingly, the configuration updates may be verified without exposing the production environment to any potential risks. Thus, the system may proactively detect cyber security threats associated with a virtual machine and automatically initiate various corrective or preventative actions.

  • Efficient recovery of multiple virtual machines
    Patent number: 11093333
    Abstract: Described is a system that recovers multiple virtual machines (or other computing resource) by leveraging similarities between recovery (or backup) data. The system may identify the recovery data for a particular virtual machine as a primary set of data using specialized calculations and/or heuristics. The system may leverage this primary set of data by replicating a data storage for the remaining number of virtual machines to be recovered. The system may then determine a remaining (or differing) set of data for each of the remaining virtual machines to be recovered. Accordingly, the system may only be required to rehydrate the differing set of data chunks and write those data chunks to the data storage associated with each recovery virtual machine. These recovery virtual machines may then be used to restore corresponding virtual machines within a production environment.

  • Fast key-value storage for continuous data protection systems
    Patent number: 11086837
    Abstract: Embodiments for providing memory for continuous data protection in a data storage system by storing a first key-value map as a data structure wherein the key is an address of a volume and the value comprises timestamp and hash value pairs for each time the address had data written thereto, and corresponding hash values of the written data, and storing a second key-value map as a data structure wherein the key comprises the hash value and the value comprises the written data. The first key-value map and second key-value map are implemented as a driver component in a server computer of the data storage system. The driver exposes a block device protocol on the server computer and leverages the key-value data structures for use with a deduplication storage system.

  • Highly scalable and consistent pluggable messaging system
    Patent number: 11086842
    Abstract: A plugin is provided to a service that includes a database for storing data corresponding to transactions received by the service and applied to the database. Upon receipt of a transaction to be performed by the service, the plugin receives a message generated by the service and associated with informing another service of the transaction. The message is stored in the database together with the transaction, the message and transaction thereby being in the same transactional context. Upon the transaction being committed, the message is also processed because the transaction and message are in the same single transactional context within the database.

  • Application aware deduplication allowing random access to compressed files
    Patent number: 11061867
    Abstract: A file is received from a client for storage at a deduplication file system. The file is in an archive file format that is used by an application on the client. The file includes subfiles compressed together in the file according to the archive file format, local headers corresponding to the subfiles, and a central directory used by the application to locate information stored in the file. The file is decompressed to store the subfiles separately. A metadata file is created that describes a structure of the file. The metadata file includes the local headers, central directory, pointers to the subfiles, but does not include the subfiles. The file is presented to the client as a single file having the archive file format. A request from the client is received to read the file and the metadata file is read to return data responsive to the request.
