Systems, devices, methods, and computer program products are provided for temporarily implementing storage access policies within a storage system on behalf of an external computing agent while the external computing agent is offline or otherwise unable to receive and process storage access requests. A storage system receives a set of storage rules from a partner computing system. The set of storage rules define a storage access policy that allows specific users or user groups to perform storage access operations within a file system hosted by the storage system. The set of storage rules also include a time to live (TTL) instruction defining a period of time for which to enable the storage access policy. Upon receiving a storage access request from an external client computing system, the storage system compares the storage access request against the storage access policy to allow or deny the storage access request.
