Claim:
1. A data center, comprising a plurality of computation nodes and a backup manager, wherein each computation node comprises a hypervisor and a memory unit, wherein the hypervisor of each computation node is configured to create a plurality of virtual machines, and wherein all virtual machines in the data center share resources of all memory units of the data center and each virtual machine is allocated a memory segment address which is allocated in a manner of uniform address allocation in the memory resources of all memory units, wherein the hypervisor of each computation node exports all data in the memory unit of the computation node and stores the exported data to a storage apparatus, and records a node number of the computation node in the storage apparatus; wherein the backup manager communicates with the storage apparatus, and obtains profiles of the plurality of virtual machines according to the node number of the computation node, wherein the profiles of the plurality of virtual machines comprises a memory segment address of each virtual machine allocated in a manner of uniform address allocation in the memory resources of all memory units shared by all virtual machines in the data center, and wherein the backup manager rearranges the data of the plurality of virtual machines in the plurality of computation nodes stored in the storage apparatus according to the memory segment address of each virtual machine.
