  • Envoy for multi-tenant compute infrastructure
    Patent number: 11281393
    Abstract: A data management and storage (DMS) cluster of peer DMS nodes manages data of a tenant of a multi-tenant compute infrastructure. The compute infrastructure includes an envoy connecting the DMS cluster to virtual machines of the tenant executing on the compute infrastructure. The envoy provides the DMS cluster with access to the virtual tenant network and the virtual machines of the tenant connected via the virtual tenant network for DMS services such as data fetch jobs to generate snapshots of the virtual machines. The envoy sends the snapshot from the virtual machine to a peer DMS node via the connection for storage within the DMS cluster. The envoy provides the DMS cluster with secure access to authorized tenants of the compute infrastructure while maintaining data isolation of tenants within the compute infrastructure.

  • MANAGING KEY ENCRYPTION KEYS USING A KEY WRAPPING TREE
    Publication number: 20190158281
    Abstract: Methods and systems for securely deleting electronic files and other data stored within a data storage system are described. Each file or separately deletable portion of data stored within the data storage system may be encrypted using a distinct data encryption key. When the file is selected for deletion, both the file and the corresponding data encryption key may be deleted. The data encryption key used for encrypting the file may be encrypted using a key encryption key. If the file and the corresponding data encryption key are both stored using an SSD, then the key encryption key may be stored using a HDD. The ability to physically delete or directly overwrite the key encryption key stored within the HDD may ensure that the file and the data encryption key stored using the SSD are no longer cryptographically recoverable.

  • DATABASE RECOVERY TIME OBJECTIVE OPTIMIZATION WITH SYNTHETIC SNAPSHOTS
    Publication number: 20200250046
    Abstract: Methods and systems for reducing the amount of time to restore a database or other application by dynamically generating and storing synthetic snapshots are described. When backing up a database, an integrated data management and storage system may acquire snapshots of the database at a snapshot frequency and acquire database transaction logs at a frequency that is greater than the snapshot frequency. In response to detecting that the database is unable to provide a database snapshot, the integrated data management and storage system may generate a synthetic snapshot of the database by instantiating a compatible version of the database locally, acquiring a previously stored snapshot of the database, applying data changes from one or more database transaction logs to the previously stored snapshot to generate the synthetic snapshot, and storing the synthetic snapshot of the database within the integrated data management and storage system.

  • Array integration for virtual machine backup
    Patent number: 11256579
    Abstract: Methods and systems for improving the performance of a primary system that is running one or more virtual machines and capturing snapshots of the one or more virtual machines over time are described. The performance penalty on the primary system when a hypervisor running the one or more virtual machines is used to capture the snapshots of the one or more virtual machines may be reduced by leveraging storage array snapshots to reduce the amount of time that the hypervisor must freeze virtual disks of the one or more virtual machines. In this case, changed block tracking information for changed data blocks associated with the snapshots may be acquired from the hypervisor and the changed data blocks themselves may be pulled from the storage array snapshots without requiring the hypervisor to keep the virtual disks of the one or more virtual machines in a frozen state.

  • Real-time detection of misuse of system credentials
    Patent number: 11550901
    Abstract: A process for detecting a threat for a file system is described. Audit events in the file system may be accessed, which may include unique file operations and duplicative file operations. The audit events may be de-duplicated to remove the duplicative file operations. Time series data may be generated that includes the unique file operations but not the duplicative file operations, and the time series data may be analyzed to determine whether a subset of the unique file operations includes file-access instructions. An observed pattern of the file-access instructions may be compared to a normal pattern of file-access instructions to determine whether the observed file-access instructions are abnormal. If the observed file-access instructions are abnormal, an alert may be generated.

  • Chunk allocation
    Patent number: 10339016
    Abstract: Methods and systems for identifying a set of disks within a cluster and then storing a plurality of data chunks into the set of disks such that the placement of the plurality of data chunks within the cluster optimizes failure tolerance and storage system performance for the cluster are described. The plurality of data chunks may be generated using replication of data (e.g., n-way mirroring) or application of erasure coding to the data (e.g., using a Reed-Solomon code or a Low-Density Parity-Check code). The topology of the cluster including the physical arrangement of the nodes and disks within the cluster and status information for the nodes and disks within the cluster (e.g., information regarding disk fullness, disk performance, and disk age) may be used to identify the set of disks in which to store the plurality of data chunks.

  • Virtual machine linking
    Patent number: 10866827
    Abstract: A method of identifying historical snapshots for a virtual machine (VM) is provided. Some example operations include receiving a request for a historical snapshot of a VM, the request indicating an ID for the VM. A detection is made that the ID for the VM in the request received is a new ID assigned to a VM. A determination is made whether the new ID corresponds to a newly created VM or an existing VM that has been previously registered using a previous ID, wherein the determining includes accessing a property of the VM including a use case identifier associated with an instant recovery request for a specific VM. Based on identifying that the new ID corresponds to a newly created VM, a new VM Group (VMG) object is created for the newly created VM corresponding to the new ID.

  • Staggered full partitioned snapshots
    Patent number: 10776039
    Abstract: Methods and systems for backing up and restoring different point in time versions of a virtual machine, a real machine, an application, a database, or a set of electronic files using a plurality of independently managed snapshot chains are described. The different point in time versions of the data being backed-up may be stored using two or more snapshot chains corresponding with two or more data partitions of the data being backed-up. Over time, additional full image snapshots may be acquired from an external server or generated locally by a storage appliance to limit the snapshot chain lengths and to limit the aggregate block chain lengths for the snapshot chains. Acquisition and generation of the additional full image snapshots may be staggered across different data partitions to limit computational and storage costs per snapshot.

  • Ransomware infection detection in filesystems
    Patent number: 11120131
    Abstract: Described herein is a system that detects ransomware infection in filesystems. The system detects ransomware infection by using backup data of machines. The system detects ransomware infection in two stages. In the first stage, the system analyzes a filesystem's behavior. The filesystem's behavior can be obtained by loading the backup data and crawling the filesystem to create a filesystem metadata including information about file operations during a time interval. The filesystem determines a pattern of the file operations and compares the pattern to a normal patter to analyze the filesystem's behavior. If the filesystem's behavior is abnormal, the system proceeds to the second stage to analyze the content of the files to look for signs of encryption in the filesystem. The system combines the analysis of both stages to determine whether the filesystem is infected by ransomware.
