摘要: A mechanism is provided in a data processing system for asynchronous replication. The creates record write log host computing device command and marking the as uncommitted. maintains copy of to be written by at device. issues from primary storage controller site. Responsive receiving an acknowledgement that have been site, marks unreplicated. replicated secondary erases deleting data.
