Abstract
Handling failure of a primary group at a first data center may be simulated by cloning the at least one storage volume at a second data center, cloning at least one storage volume at a third data center, cloning at least one of: buffers used for providing data to the asynchronous backup group and maps used to maintain a record of data sent to the synchronous backup group but not yet sent to the asynchronous backup group; and simulating resuming work at one of the second data center and the third data center using at least one of clones of the buffers and clones of the maps.
