Abstract
Methods, apparatus, and computer-accessible storage media for providing redundant storage gateways. A client may create a storage gateway group and add storage gateways to the group. The client may assign one or more volumes on a remote data store to each the storage gateways in the group. Volume data for each storage gateway in the group may be replicated to at least one other storage gateway in the group. If one of the gateways in the group becomes unavailable, one or more other gateways in the group may take over volumes previously assigned to the unavailable gateway, using the replicated data in the group to seamlessly resume gateway operations for the respective volumes. Client processes that previously communicated with the unavailable gateway may be manually or automatically directed to the gateway(s) that are taking over the unavailable gateway's volumes.
