Stratus ftServer

Using a combination of replicated hardware components working in 'lockstep' mode and the unique 'automated uptime layer' means even in memory data is constantly protected and maintained.  Other issues are captured, analysed and reported to Stratus.  This allows support personnel to take a proactive approach to correcting software problems before they recur.


Add on the everRun Extend DR module to your ftServer deployment for complete end to end application protection.  Local failures are then handled by ftServer; complete site outages due to server room, fire/flood/disaster are handled by the DR failover module to your chosen disaster recovery site.


ftServer along with everRun Extend will keep your systems up and running should local or full site disaster occur.  A robust backup policy still needs to be adopted.  By adding on Arcserve Unified Data Protection (UDP) also available from Stratus Technologies, granular incremental backups with configurable version control and point in time recovery can be established.  Backups can be configured to your local network devices and/or hosted cloud servers.
