Abstract
A variety of flexible conflict resolution policies are provided for loosely coupled devices to implement according to a variety of different synchronization scenarios. Choosing a conflict resolution policy, such as “Most Frequent Updater,” “Priority,” “PerCent Change,” “Arbiter Deadlock Resolution,” etc., enables devices to select how and when to resolve such synchronization conflicts. In addition, with reference to a conflict log, a user or synchronizing application can roll back synchronization state to a time before a conflict may have arisen, so that the user or application can undo a resolution of a conflict and/or the user or application can apply an alternative conflict resolution policy moving forward from that time.
