Components
XP Continuous Access Journal operations involve local arrays at the primary and secondary sites,
physical communications paths between these arrays, and XP Command View Advanced Edition
Software or XP Remote Web Console. XP Continuous Access Journal copies the original online
data at the primary site to backup volumes at the secondary site through dedicated Fibre Channel
remote copy connections using a journal volume. You can operate XP Continuous Access Journal
with the user-friendly GUI environment using XP Command View Advanced Edition Software or
XP Remote Web Console.
NOTE: Host failover software is required for effective disaster recovery with XP Continuous Access
Journal.
