Abstract: A method comprises selecting at least a given stub file of one or more stub files for migration from a source storage location to a target storage location. The selection of the given stub file is based at least in part on a database entry comprising source storage location path information for the given stub file. The one or more stub files correspond to one or more archived files, and the one or more stub files and one or more non-stub files are stored in the source storage location. In the method, the given stub file is migrated to the target storage location without migrating the one or more non-stub files to the target storage location. The method further includes modifying the database entry by replacing the storage location path information with target storage location path information for the given stub file.

Abstract: Methods, apparatus, and processor-readable storage media for efficient synchronization of a cloud enabled file system database during a snapshot restore operation are provided herein. An example computer-implemented method includes intercepting a user request to initiate a snapshot restore operation on a file system associated with a local storage system, wherein the file system comprises one or more stub files that are indicative of locations of cloud objects comprising files that were previously sent from the local storage system to a cloud storage platform; prior to the snapshot restore operation being performed, creating a current snapshot of the file system; obtaining an indication that the file system was successfully restored on the local storage system; and using the current snapshot to perform a synchronization operation, wherein the synchronization operation deletes one or more orphan cloud objects in the cloud storage platform that resulted from the snapshot restore operation.

Abstract: Methods, apparatus, and processor-readable storage media for deleting orphan archived files from a storage array using a time-based decision algorithm are provided herein. An example computer-implemented method includes traversing a database of a local storage system to identify a record associated with a stub file, wherein the record is indicative of a time of a client operation, involving the stub file, on a file system of the local storage system; identifying a particular snapshot in a set of available snapshots of the file system; and providing an indication to a cloud storage platform to delete a cloud object corresponding to the stub file in response to determining that the time of the client operation occurred earlier than a snapshot time associated with the particular snapshot in the set.

Abstract: A data processing system backs up snapshots of storage objects to cloud storage by identifying to a cloud gateway a set of snapshots to be archived, and making the set available to the cloud gateway. Upon request by the cloud gateway, snapshot metadata is provided that includes offsets and lengths of data extents of the set of snapshots. On further request of the cloud gateway using the metadata, the data extents of the set of snapshots are provided to the cloud gateway, which uses the extents to create corresponding objects and stores the objects in the cloud storage, each object including the data extents and the snapshot metadata for a respective snapshot. Backup and restore are initiated by the gateway or by the data storage system in different embodiments.

Abstract: One embodiment of the present invention provides a system that determines a feasible cell placement for an integrated circuit design. During operation, the system receives an input cell placement, which is typically determined using a quadratic placement technique. Next, the system receives a set of regions within the integrated circuit design. Each region has a capacity constraint which specifies an upper limit on the total cell area that can be placed within the region. The system then generates a bi-partite graph which comprises instance vertices, region vertices, and edges. An instance vertex is associated with a cell instance, a region vertex is associated with a region, and each edge is incident on an instance vertex and a region vertex. Each edge is assigned a cost that indicates the cost of placing the associated cell instance in the associated region. Next, the system associates edges with shadow edges. Note that an edge and an associated shadow edge are incident to the same instance vertex.
