A rolling disaster usually starts with a power outage or a problem with network communication lines. It is an event in which replication to the secondary (disaster recovery) site fails before the primary (production) data center fails. During the interim between replication failure and failure of the primary data center, the primary data center’s production servers continue to produce data that is not being replicated (unless you have Axxana’s Phoenix). Suffice it to say, when data is created and not replicated—even for a few seconds—data loss is guaranteed.
