In a computing environment, a method for providing a data backup function without transferring data across a local area network includes providing a plurality of resources including at least a client resource requiring a periodic servicing operation, a service provider resource capable of providing that servicing operation. At least one of the client resource and the service provider resource, such as a data backup resource, are defined by virtual machines. The client resource and the service provider resource are transparently co-located by transferring the resource defined by a virtual machine to the physical machine hosting the other resource, and the service provider resource performs the data backup function without need of transferring the data being backed up across a local area network. Methods, computer systems, and computer programs available as a download or on a computer-readable medium for installation according to the invention are provided.
