Methods and systems for a reciprocal backup of data, including files, directories, and application data are provided. Example embodiments provide a Reciprocal Backup System (“RBS”), which enables users of two or more computer systems connected over a network to engage each other for automated reciprocal backup needs using peer-to-peer computing techniques. The peer computer systems negotiate a reciprocal backup relationship where each provides the other with backup storage in a secure fashion. The intermittent nature of some partners is handled automatically by the RBS, which supports fully automated and scheduled backups as well as immediate backup and restoration of data objects. In one embodiment, the RBS comprises reciprocal backup system partner support and one or more storage repositories. The RBS partner support includes a reciprocal backup manager and scheduler and a reciprocal backup agent. These components cooperate to provide the backup and restoration operations of the RBS.

A system, method, and program product is provided that deploys an operating system. The first computer system sends a Wake-on-LAN instruction and boots each of the second computer systems. The second computer system identifies a set of third computer identifiers that corresponds to each of the selected second computer systems. The second computer systems send the Wake-on-LAN instruction to each of the third computer systems, and the third computer systems are booted over the computer network from the second computer systems. A control file lists the first computer system as a “server” of the second computer systems and lists the second computer systems as “servers” of the third computer systems. The control file is transmitted from a server to each of the server's clients. When a client is booted, it checks the control file to determine if the client is also a server to other computer systems.

Disclosed is a data synchronization service for use in a peer-to-peer computing environment. Selected data objects are copied onto selected computing devices. A service running on each device monitors data objects for changes. When a change is detected, the service sends a change notification to the other devices so that they can update their copies of the data object. A user can access a data object from any device, knowing that he will retrieve the latest version of the data object. Instead of incurring the costs of storing a large file on every device, a user “ghosts” the file on some devices. A ghosting device stores only metadata about the file rather than the entire file. The user accesses the file through the ghost: access requests are sent to a device that holds the actual contents, and those contents are presented to the user as if they were stored locally.
