Abstract: Policy-based performance of storage management operations on objects of a file system using an index of the file system is presented herein. An object policy component maintains an object policy specifying that an operation is to be performed on an object of objects that have been stored in a system in response to a determination that a state of the object satisfies a defined policy condition. Further, a job component periodically accesses an index data structure of the system comprising respective attributes of the objects that have been stored in the system, and in response to the state of the object being determined, based on a group of attributes of the respective attributes of the object, to satisfy the defined policy condition, performs the operation on the object.

Abstract: A system for updating a security sensor monitoring potential security threats on an endpoint computing device includes is configured to access an updated version of the computing environment running on the end-point computing device. The system builds an updated security sensor based at least in part on the updated version of the computing environment. The system determines compatibility of the updated security sensor with an earlier-version of the computing environment by comparing the updated security sensor with an earlier version of the security sensor that was built for the earlier-version computing environment. The system communicates an indication of the compatibility to the end-point computing device.

Abstract: The described technology is generally directed towards creating snapshot change lists that describe differences between snapshots that capture file system states at different times. Also described is the use of snapshot change lists for updating an index that represents the objects in the file system at a given time. Data services jobs may be run against the index to select files, instead of running the jobs against the actual file system namespace, which is typically far more efficient when dealing with large file system namespaces.

Abstract: Implementations are provided herein for data deduplication, and more particularly, to post-process data deduplication on a large scale out storage system. Multiple techniques and implementations are disclosed that offer greater efficiency, higher performance, and more stability when performing post-process data deduplication at large scale. Disclosed implementations are based on a process for data deduplication involving four main phases: enumeration, commonality, sharing, and update. Multi-level hashing can be used to identify candidates for deduplication during the enumeration phase, providing a more efficient use of compute resources. In addition, datasets can be phase rotated through the post-process deduplication steps providing a more controllable deduplication environment as well as a more efficient use of resources.
