A method of restoring processes within a process domain begins with a step of restoring a tree of processes in which at least two of the processes share at least a resource. The method continues with a step of restoring a checkpoint state of each resource used by the processes after a time when a possible need for a restoration state of the resource exists. According to an embodiment, the restoration state comprises information used by the method during the step of restoring the tree of processes. According to another embodiment, the restoration state comprises information used by the method during the step of restoring the checkpoint state of one or more particular resources. The method concludes with a step of resuming execution of each process after restoration of the checkpoint state of the resources used by the process.
