  • Patent number: 11442819
    Abstract: Described is a system (and method) for managing specialized metadata that may be used to manage and search incremental backup data stored on a cloud-based object storage. The system may create and store such metadata as part of a specialized metadata database that includes a data catalog and a backup catalog. The system may leverage the metadata database to initiate operations to efficiently manage incremental backup data stored on the object storage. For example, the metadata may be relied upon to efficiently reconstruct (e.g. synthetically) the client data to a point-in-time of any incremental backup. In addition, the metadata may include properties of the backed-up data, which are maintained separately from the backup data stored as objects. Accordingly, these properties may be searched to identify and locate backup data without having to retrieve the stored objects.

  • Publication number: 20220283904
    Abstract: Described is a system for synchronizing expiration times for incremental backup data stored on a cloud-based object storage. More particularly, the system may provide a layer of intelligence when updating the expiration times associated with backup data to ensure that a full recovery of the client data to a point-in-time of any incremental backup may be performed. To provide such a capability, the system may maintain specialized metadata identifying expiration times for objects and a list of objects required to perform a full recovery to a point-in-time for each of the performed backups (e.g. full or incremental). The system may access this metadata to identify which objects stored by a previous backup are still referenced by a subsequent backup. Based on the identified objects, the system may synchronize object expiration times to ensure objects are not prematurely deleted from the object storage.

  • Publication number: 20220269809
    Abstract: Described is a system that leverages object storage provided access controls to secure backup data stored on a third-party cloud-based object storage. More particularly, the system may implement a mechanism that ensures that a backup system acts as a gateway for accessing the backup data stored on the object storage. For example, the system may prevent object storage administrative accounts that are authorized to access data directly on the storage from maliciously or inadvertently jeopardizing the integrity of the backup data. Moreover, the backup system may encrypt the backup data to prevent such administrative accounts from performing various backup related operations such as data recovery. Accordingly, to perform backup operations and decrypt the backup data, an account must be authorized by the backup system acting as an exclusive gateway to the backup data stored on a third-party storage.

  • Patent number: 11416159
    Abstract: A method and system for prioritizing critical data object storage during backup operations. Specifically, the method and system disclosed herein entail reordering data objects, awaiting being written to storage and thus queued in one or more data object queues, in accordance with a nearest-critical based sequential order. The nearest-critical based sequential order may be derived through modified weight-based Euclidean distances calculated between adjacent data object pairs queued in any given data object queue. Further, the calculated modified weight-based Euclidean distances incorporate data criticality factors associated with the adjacent data object pairs. By reordering data objects in a nearest-critical based sequential order, critical data objects may be written into storage first, thereby avoiding possible critical data loss should a disaster occur during backup operations.

  • Publication number: 20220229733
    Abstract: Described is a system for rule-based re-tiering of backup data stored on a cloud-based object storage. More specifically, the system may re-tier objects based on one or more storage rules such that the system retains the ability to efficiently perform a full restore of backup data even when incremental backups are performed to a cloud-based object storage. To provide such a capability, the system may maintain a specialized metadata database that stores information indicating the backup time for each backup, and a list of objects required to perform a full restore to each of the backup times. Accordingly, when initiating a re-tiering based on one or more storage rules, the system may intelligently select candidate objects for re-tiering by leveraging the metadata database to ensure that objects that may still need to be referenced are not unnecessarily moved to a lower storage tier.

  • Publication number: 20220214946
    Abstract: Described is a system for managing backup data stored on a cloud-based object storage irrespective of the storage provider. The system may include a server (or gateway) that provides a backup service, and acts as an intermediary between a client device and object storage. To provide such capabilities, the system may manage an application programming interface (API) that provides a uniform set of methods to a client device irrespective of the destination object storage provider. A function library may include provider-specific functions that invoke corresponding storage-layer operations provided by the destination object storage. The server may also manage an operation pool to schedule operations and saturate bandwidth to the object storage. The server may also implement a specialized metadata database to provide further storage efficiencies by storing certain backup data exclusively within the metadata database.
