Aspects of the subject matter described herein relate to resource
replication systems. In aspects, a mechanism is described that maintains
replicated resources on a slave member that participates in a replica
group. The slave member detects that a local resource has been updated
locally. If the resource was created locally in the update, the slave
member deletes the local resource. Otherwise, the slave member determines
an upstream partner from which to install a replacement resource and then
installs the replacement resource. In aspects, this behavior undoes local
updates to local resources that occur on the slave member.
