Automated failover/failback was in the news recently with the FalconStor RecoverTrac data mobility upgrade. How common is this type of technology today? Is failover/failback becoming any less of a pain point for IT?
Failover and failback technologies have existed for quite some time. The thing that makes FalconStor so unique is that they have moved failover/failback automation into disaster recovery software. Failover and failback capabilities have traditionally been regarded as disaster avoidance capabilities rather than disaster recovery capabilities. As such, it is a bit outside of the norm for a backup vendor to take on failover/failback automation.
Failover/failback has always been a major pain point for admins. Fortunately, the various software vendors have taken steps to make failover and failback more intelligent so as to reduce the administrator's workload. For example, rules can be used to ensure that all of the virtual machines that are associated with a business application can failover together. There are also technologies available to assign new IP addresses after a failover and to make any required changes to DNS records.
