Abstract
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.
