A network storage system may receive the contents of a storage device attached to a client device to the network storage system. The network storage system may then redirect access to the contents of the client device to the network storage system. The storage device may then be removed or repurposed. Storage device management may be performed by the client device or the network storage system. A policy may be used to define under what circumstances the contents of a storage device may be moved to a network storage system, or data movement may be initiated by a user. Any access permissions or other metadata associated with files on the original storage device can be preserved.
