  • Patent number: 11977461
    Abstract: Techniques are provided for incrementally restoring a virtual machine hosted by a computing environment. In response to receiving an indication that the virtual machine is to be incrementally restored, a snapshot of the virtual machine may be created while the virtual machine is shut down into an off state. The snapshot is transmitted to a storage environment as a common snapshot. The snapshot and the common snapshot are common snapshots comprising a same representation of the virtual machine. The common snapshot and a prior snapshot of the virtual machine are evaluated to identify a data difference of the virtual machine between the common snapshot and the prior snapshot. An incremental restore is performed of the virtual machine by transmitting the data difference from the storage environment to the computing environment to restore the virtual machine to a state represented by the prior snapshot.

  • Publication number: 20240141537
    Abstract: The present disclosure provides a superhydrophobic and self-cleaning anticoagulant composite coating material and a preparation method and use thereof, and relates to the technical field of biomedical materials. In the coating material provided by the present disclosure, a titanium dioxide nanotube-based structure increases microscopic roughness of a surface of a titanium-based metal substrate, and a hydrophobic modification layer reduces surface energy of the material. The rough structure and the hydrophobic modification layer have a synergistic effect to construct a superhydrophobic surface, making the surface of the material have self-cleaning characteristics and low adhesion. Air can be retained on the surface of the material to form an air layer, thereby reducing the contact area between the material and bacteria and platelets in the blood, and inhibiting adhesion of the bacteria, platelets, and plasma proteins to the material.

  • Publication number: 20240134759
    Abstract: Techniques are provided for backing up virtual machines from a computing environment to a storage environment. A virtual machine agent is utilized to generate a snapshot of the virtual machine. Metadata comprising a snapshot identifier of the snapshot and virtual disk information of virtual disks captured by snapshot is generated at the computing environment. The metadata is retrieved and used to create a metafile that is transferred to the storage environment within which snapshots of the virtual machine are to be stored. The snapshot is retrieved from the computing environment and is packaged into a snapshot package having a protocol format used by the storage environment. The snapshot package is transferred to the storage environment.

  • Patent number: 11966361
    Abstract: With a forever incremental snapshot configuration and a typical caching policy (e.g., least recently used), a storage appliance may evict stable data blocks of an older snapshot, perhaps unchanged data blocks of the snapshot baseline. If stable data blocks have been evicted, restore of a recent snapshot will suffer the time penalty of downloading the stable blocks for restoring the recent snapshot. Creating synthetic baseline snapshots and refreshing eviction data of stable data blocks can avoid eviction of stable data blocks and reduce the risk of violating a recovery time objective.

  • Publication number: 20240118977
    Abstract: Techniques are provided for incremental backup to an object store. A request may be received from an application to perform a backup from a volume hosted by a node to a backup target within the object store. A set of changed files within the volume since a prior backup of the volume was performed to the backup target is identified, along with metadata associated with the set of changed files. The metadata is utilized to identify changed data blocks comprising data of the set of changed files that was modified since the prior backup. The changed data blocks are backed up to the object store.

  • Patent number: 11921671
    Abstract: Systems, methods, and machine-readable media for creating, deleting, and restoring volume snapshots in a remote data store are disclosed. A storage volume and a storage operating system are implemented in a software container. Through a user interface, a user may create a snapshot of the volume to a cloud storage. A user may also delete individual snapshots from the cloud storage. Further, deletion of a most recent snapshot may occur by awaiting deletion (though marking as deleted to the user) until a next snapshot is received. Snapshots in the cloud storage are manipulatable even after destruction of the source volume (by destruction of the container, for example). A controller outside the container is used by implementing the same API as the controller in the container had. Full restores of snapshots in the cloud are also possible even when the original container and volume have been destroyed.

  • Patent number: 11921597
    Abstract: One or more techniques and/or computing devices are provided for cross-platform replication. For example, a replication relationship may be established between a first storage endpoint and a second storage endpoint, where at least one of the storage endpoints, such as the first storage endpoint, lacks or has incompatible functionality to perform and manage replication because the storage endpoints have different storage platforms that store data differently, use different control operations and interfaces, etc. Accordingly, replication destination workflow, replication source workflow, and/or a proxy representing the first storage endpoint may be implemented at the second storage endpoint comprising the replication functionality.

  • Publication number: 20230334013
    Abstract: A storage appliance arranges snapshot data and snapshot metadata into different structures, and arranges the snapshot metadata to facilitate efficient snapshot manipulation, which may be for snapshot management or snapshot restore. The storage appliance receives snapshots according to a forever incremental configuration and arranges snapshot metadata into different types of records. The storage appliance stores these records in key-value stores maintained for each defined data collection (e.g., volume). The storage appliance arranges the snapshot metadata into records for inode information, records for directory information, and records that map source descriptors of data blocks to snapshot file descriptors. The storage appliance uses a locally generated snapshot identifier as a key prefix for the records to conform to a sort constrain of the key-value store, which allows the efficiency of the key-value store to be leveraged.

  • Publication number: 20230281088
    Abstract: Techniques are provided for orchestrating operations between a storage environment and a computing environment hosting virtual machines. A virtual machine proxy, associated with a computing environment hosting a virtual machine, is accessed by an orchestrator to identify the virtual machine and properties of the virtual machine. A storage proxy, associated with a storage environment comprising a volume within which snapshots of the virtual machine are to be stored, is accessed by the orchestrator to initialize a backup procedure. The orchestrator utilizes the virtual machine proxy to create a snapshot of the virtual machine. The orchestrator utilizes the storage proxy to back up the snapshot to the volume using the backup procedure.
