  • 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.

  • Publication number: 20220229732
    Abstract: Described is a system for intelligent re-tiering of backup data stored on a cloud-based object storage. More specifically, the system may re-tier objects 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 using a threshold time (e.g. expiry) to select object candidates for re-tiering, the system may leverage 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: 20220229735
    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: 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.

  • Publication number: 20220197749
    Abstract: Described is a system (and method) for specialized data management when performing incremental backups to a cloud-based object storage. When backing up client data, the server may utilize incremental backups to conserve the amount of storage space required on the object storage. However, the server may implement a configuration that enables full reconstruction of the client data at the time of recovery. To provide such capabilities, the server may leverage a specialized metadata database. The metadata database may be an embedded database maintained by the server. The server may leverage the metadata database to provide further storage efficiencies by storing certain incremental backup data exclusively within the metadata database. Accordingly, the server may implement a data management configuration as part of a backup service that conserves storage usage, and as a result, storage costs when using on a third-party cloud-based object storage.

  • Publication number: 20220129352
    Abstract: Described is a system for cloud-based processing of backup data for storage onto various types of object storage systems. A specialized cloud-based component (e.g. proxy server) may act as an intermediary when backing up data from a client system to an object storage. For example, the cloud-based component may be provided as part of backup service that operates in conjunction with a client system. Accordingly, the system may allow different clients of a backup service to efficiently and seamlessly interact with the different third-party object storage providers via a single cloud-based component. To provide such object-storage-agnostic functionality, the cloud-based component may include a function library that includes object-storage-specific functions. For example, the cloud-based component may invoke a specific set of operations that interact with a storage API provided by a particular object storage provider.

  • Publication number: 20220129183
    Abstract: Described is a system (and method) for providing multiple types of granular delete operations for a cloud-based object storage. The system may include a server that acts as an intermediary between a client device and an object storage that stores client data. The server may allow a client to perform a hard delete (or permanent) delete and a soft delete. The server may perform a specialized processing to synthetically create the soft delete feature using a permanent object delete operation provided by the object storage. The specialized processing may include manipulating retention periods associated with objects depending on whether the object is subject to a hard delete or a soft delete. As a result, the server may provide the ability for clients to perform a soft delete at an object level using existing storage level APIs that do not directly support such a feature.
