Abstract

A system, method, and program product is provided that receives a backup request at a virtual input/output server (VIOS) from a client of the VIOS. The backup request corresponds to a virtual nonvolatile storage that is used by the client. The VIOS retrieves data from the nonvolatile storage device where the virtual nonvolatile storage is stored. The VIOS transmits the retrieved data to a backup server via a computer network, such as the Internet. In one embodiment, a backup software application runs on the VIOS client and a backup proxy software application runs on the VIOS.
