Abstract: Techniques for providing direct access to backup data can include: receiving a selection of a backup of a file system, wherein the backup is stored on a backup system connected to a data storage system; creating, in accordance with said selection of the backup, a remote copy of the backup, wherein the remote copy is stored on the backup system; generating a proxy file system for the remote copy on the backup system, wherein the proxy file system is mapped by the data storage system to the remote copy on the backup system; and providing a host with direct access to the remote copy using the proxy file system.

Abstract: A method, computer program product, and computing system for receiving a selection of one or more secure snapshots to remove from a storage system. A snapshot deletion key may be received from the storage system. The selection of the one or more secure snapshots and the snapshot deletion key may be provided to a storage system support service. A snapshot deletion response may be received from the storage system support service. The snapshot deletion response and the selection of the one or more secure snapshots may be authenticated via the storage system. In response to authenticating the snapshot deletion response and the selection of the one or more secure snapshots, the one or more secure snapshots may be unlocked for deletion.

Abstract: A data path connection can be established between a target of a remote source system and an initiator of a local destination system. A storage object of the remote source system exposed over such a data path connection can be mapped to a local storage object name of the local destination system. Such a remote storage object of the remote source system can be accessed as a local storage object of the local destination system using the local storage object name. Within the destination system, the local storage object name of the destination system can be used as a proxy to access the remote storage object of the remote source system. Accessing the remote storage object from the destination system can be used in several data mobility use cases, including, but not limited to, offloaded data copy across arrays, snapshot mobility and backup use-cases.

Abstract: Techniques for creating and using snapshots may include: receiving a request to create a new snapshot of a source object; determining whether a first generation identifier associated with the source object matches a second generation identifier associated with a base snapshot of the source object; determining whether the source object has been modified since the base snapshot was created; and responsive to determining the first generation identifier matches the second generation identifier and also determining that the source object has not been modified since the base snapshot was created, associating the new snapshot with the base snapshot thereby indicating that the new snapshot and the base snapshot have matching content and denote a same point in time copy of the source object.

Abstract: Techniques for taking and managing snapshots comprise: capturing a first snapshot of a virtual machine (VM), wherein the first snapshot is a managed snapshot exposed to a virtualization environment and a data storage system environment providing physical storage for data of the VM; capturing a second snapshot of the VM, wherein the second snapshot of the VM is a managed snapshot of the VM is exposed to the virtualization environment and the data storage system environment; and converting the second snapshot of the VM from a managed snapshot of the VM to an unmanaged snapshot of the VM. Subsequent to completing the converting, the second snapshot of the VM that is an unmanaged snapshot is exposed to the data storage system environment and subsequent to completing the converting, the second snapshot of the VM that is an unmanaged snapshot is not exposed to the virtualization environment.
