Abstract: Techniques are provided for on-demand creation and/or utilization of containers and/or serverless threads for hosting data connector components. The data connector components can be used to perform integrity checking, anomaly detection, and file system metadata analysis associated with objects stored within an object store. The data connector components may be configured to execute machine learning functionality to perform operations and tasks. The data connector components can perform full scans or incremental scans. The data connector components may be stateless, and thus may be offlined, upgraded, onlined, and/or have tasks transferred between data connector components. Results of operations performed by the data connector components upon base objects may be stored within sibling objects.

Abstract: Techniques are provided for implementing a snapshot copy operation between endpoints. One or more snapshots (e.g., snapshots of an on-premise volume) is stored within a source endpoint, such as a source bucket of an object store. A post operation is executed to copy objects comprising snapshot data of a snapshot from the source endpoint to a destination endpoint. A get operation and a tracking object such as a cookie is used to track progress of copying the objects from the source endpoint to the destination endpoint. The tracking object is used to restart the copying of the objects from a point where the copying left off (e.g., in the event there is a failure) without having to restart from the beginning.

Abstract: Techniques are provided for managing objects within an object store. An object is maintained within an object store. The object is used to store data of a snapshot of a file system hosted by a remote computing device. A determination is made that the snapshot was deleted by the remote computing device. Bitmaps describing objects within the object store that are related to snapshots of the file system are evaluated to determine that the object is unique to the deleted snapshot. The object is freed from storage within the object store.

Abstract: Techniques are provided for tiering snapshots to archival storage in remote object stores. A restore time metric, indicating that objects comprising snapshot data of snapshots created within a threshold timespan are to be available within a storage tier of a remote object store for performing restore operations, may be identified. A scanner may be executed to evaluate snapshots using the restore time metric to identify a set of candidate snapshots for archival from the storage tier to an archival storage tier of the remote object store. For each candidate snapshot within the set of candidate snapshots, the scanner may evaluate metadata associated with the candidate snapshot to identity one or more objects eligible for archival from the storage tier to the archival storage tier, and may archive the one or more objects from the storage tier to the archival storage tier.

Abstract: Techniques are provided for volume group backup, volume group restore, and volume group garbage collection for volume groups backed up to an object store. A volume group workflow is implemented to orchestrate individual consistent volume workflows that are separately and individually implemented by nodes hosting constituent volumes of a volume group. The volume group workflow and the individual consistent volume workflows are performed to back up the volume group to the object store, restore a volume group backup from the object store to a restore destination, and/or perform garbage collection on slots of objects storing data unique to a volume group backup to delete.

Abstract: Techniques are provided for implementing management requests associated with objects of an object store. A data connector component may be instantiated as a container for processing management requests associated with backup data stored within an object store as an object according to an object format. A management request associated with the backup data may be received by the data connector component. A structure associated with the object having the object format may be traversed by the data connector component to identify the backup data. The data connector component may be implemented upon the backup data stored within the object.

Abstract: Techniques are provided for virtual machine hosting and disaster recovery across virtual machine hosting environments, such as hypervisors, supporting different virtual machine formats. A virtual machine is hosted by a first hypervisor that supports a first virtual machine format. Snapshots capturing virtual machine disks of the virtual machine are created and backed up to a cloud storage environment. The snapshots are used to restore the virtual machine as a destination virtual machine hosted by a second hypervisor supporting a second virtual machine format different than the first virtual machine format. As part of restoring the destination virtual machine, virtual machine disks of the virtual machine are reformatted according to the second virtual machine format supported by the second hypervisor.

Abstract: Techniques are provided for a snapshot difference interface integrated into an object store data management container. The snapshot difference interface is capable of interpreting an object format and snapshot file system format of snapshots backed up to an object store within objects formatted according to the object format. The snapshot difference interface can identify differences between snapshots, such as files that changed between the snapshots, while the snapshots are still resident within the object store. Because the snapshot difference interface does not retrieve the snapshots from the object store, security is improved, resource and network consumption is reduced, there is less of an impact upon client I/O processing, and a catalog of the snapshots can be more efficiently built and recovered in the event of corruption.
