Abstract
In one aspect, a method includes performing a failover in a journal-based replication system and performing a failback in the journal-based replication system without loss to journaling. In another aspect, an article includes a non-transitory machine-readable medium that stores executable instructions. The instructions cause a machine to perform a failover in a journal-based replication system and perform a failback in the journal-based replication system without loss to journaling. In a further aspect, an apparatus includes circuitry configured to perform a failover in a journal-based replication system and perform a failback in the journal-based replication system without loss to journaling.
