A coordinating push and user-initiated synchronization method and system. Initially, changes to a local application data store are detected and records affected by the change are identified. At some point, a record affected by a detected change is pushed to a remote system where it is ascertained whether the pushed record, in its current form as affected by the detected change, has already been replicated in or deleted from a remote application data store through user-initiated synchronization. If not, the pushed record is used to update the remote application data store. Instead, at some point it may be ascertained whether the identified record, in its current form as affected by the detected change, has been replicated in or deleted from the remote application data store through push synchronization as just described. If not, the remote application data store is synchronized with the local application data store.
