ABSTRACT:
Described are methods, systems, and apparatus, including computer program products, for achieving distributed asynchronous ordered replication. Distributed asynchronous ordered replication includes creating a first journal for a first set of I/O data, creating a second journal for a second set of I/O data, and temporarily preventing committal, of the second set of I/O data until the second journal is created. In some examples, the first and second journals comprise entries. The entries of the first and second journals include counter values. The entries of the first journal typically have a different counter value than the entries of the second journal.
