Disclosed are methods and the like that provide for transforming replicated data for consumption in the cloud, for example. Such methods can include attaching a target gateway node at a secondary site to a storage device at the secondary site, searching for an identifier stored in the storage device, and storing replicated data in the replication volume. The identifier is associated with an offset stored in the storage device, and the offset identifies a starting location of a replication volume in the storage device. The replicated data is received by the target gateway node from a source gateway node at a primary site. A starting location is received with the replicated data. The target gateway node stores the replicated data at a first location in the storage volume, and the first location is determined based, at least in part, on the starting location and the first storage location.

Low cost, heterogeneous method of transforming replicated data for consumption in the cloud

Presented herein is functionality for using a recovery computing system to perform a failover where the recovery computing system is communicatively coupled to a homogeneous and/or heterogeneous primary computing system. In one embodiment, this functionality allows the recovery computing system to disconnect a first recovery application node from a contiguous storage volume after the contiguous storage volume had been created by the first recovery application node, and to then use a recovery gateway node to store replicated data on the continguous storage volume, where the recovery gateway node and the contiguous storage volume are both coupled to the recovery computing system. In response to detecting a failure on the primary computing system, performing a failover to the recovery computing system, where performing the failover comprises attaching the contiguous storage volume to a second recovery application node and bringing the second recovery application node online.

Various systems, methods and apparatuses for replicating data from homogeneous and/or heterogeneous primary computing systems to a single recovery computing system are presented. In one embodiment, the methods, systems and apparatuses described herein allow a computing system to receive information from a remote computing system, where the information contains at least data and a logical storage location corresponding to the location of the data in a logical storage unit of the remote computing system. Upon receiving the data and associated logical storage location, the methods, systems and apparatuses described herein can store the information at a specific location in a storage device such as, for example, a block storage device. The specific location can be determined, for example, based on the logical storage location provided by the remote computing system and an offset associated with the starting location of the relevant logical storage unit on the storage device.
