SnapMirror ® Transparent Failover for Windows File Sharing Primary Data Center DR Site FAS NearStore ® Virtual File Manager Global Namespace Users and Applications  “Namespace” isolates users from hardware  In the event of a disaster, VFM redirects users to the secondary storage  Auto synchronization  As qtrees and shares are added to primary, no additional steps required to keep the secondary synchronized

Closing Thoughts 13  The Recovery Continuum  It isn’t backup or disaster recovery, your services should always be on and accessible  Continuous (Near Continuous) Availability is key  If a user can always find their application or data, there is no (almost) need to fail-over  A lot of the components are already in place in many organizations  It’s a matter of how you deploy them
