    Abstract: In one embodiment, a cloud digital video recorder system includes a broadcast content receiver operative to receive broadcast content, a spill agent operative to generate a plurality of different time-period, non-user initiated, recording requests, and a content recorder operative to receive a plurality of user-initiated recording requests of a plurality of users, receive the plurality of different time-period, non-user initiated, recording requests of the spill agent, record the broadcast content into a content storage according to the plurality of user-initiated recording requests and the plurality of different time-period, non-user initiated, recording requests, receive a user-initiated retroactive recording request for a first portion of the broadcast content which has already been recorded to the content storage, and generate a pseudo-recording from the first portion of the broadcast content stored in the content storage according to the user-initiated retroactive recording request. Related apparatus and methods are also described.

    Abstract: A disclosed method is performed at a fault-tolerant object-based storage system including M data storage entities, each is configured to store data on an object-basis. The method includes obtaining a request to store N copies of a data object and in response, storing the N copies of the data object across the M data storage entities, where the N copies are distributed across the M data storage entities. The method additionally includes generating a first parity object for a first subset of M copies of the N copies of the data object, where the first parity object is stored on a first parity storage entity separate from the M data storage entities. The method also includes generating a manifest linking the first parity object with one or more other subsets of M copies of the N copies of the data object.

    Abstract: In one embodiment, a first value is computed on a networked computing device, the first value being associated with storing a recording of a broadcast video at a first cloud storage device situated in a first one of a plurality of regions, for playback on a remote client device situated in the first one of the plurality of regions, the first value being a measure of user consumption patterns and use of computing and network resources. A second value is computed on the networked computing device, the second value being associated with storing the recording of the broadcast video at a second cloud storage device situated in a second one of the plurality of regions, for playback on a remote client device situated in the second one of the plurality of regions, the second value being a measure of user consumption patterns and use of computing and network resources. The first and second values are compared on the networked computing device in order to determine a preferred storage region, the recording of the broadcast video is stored on the one of the first cloud storage device and the second cloud storage device in the preferred storage region, and the one of the first cloud storage device and the second cloud storage device in the preferred storage region is instructed to store the recording of the broadcast video. Related hardware, systems, and methods are also described.
