PHD Virtual, a Unitrends Company, is an Elite level VMware Technology Alliance Partner, has pioneered the concept of Disaster Recovery Assurance. Disaster Recovery Assurance leverages the synergies between the virtualization and storage layers in private clouds, enabling the orchestration and full automation of recovery processes. Recovery can be exercised without
human intervention or impacting production systems. Essentially, Disaster Recovery Assurance provides automated enforcement of RPOs (maximum data loss) and the continuous measurement and compliance of RTOs (maximum outage time).
ReliableDR from PHD Virtual enables datacenter managers to replace outdated or ineffective legacy DR processes with frequent and automated DR testing of all x86 IT services. Unlike legacy DR tests, which are typically run once per year or at best quarterly, ReliableDR enables DR testing to be performed as often as required, typically on a daily or hourly basis. And ReliableDR generates certified recovery points that provide stopgaps in time against data corruption, bad patches, sabotage and other logical disasters.
ReliableDR orchestrates the physical and virtual infrastructure components such as hypervisors, storage, operating systems, and applications, in order to enforce coherent and dependency aware IT Service recovery policies. These policies can be set by IT or business management and are verified automatically through a closed-loop mechanism that rectifies configuration drift and
identifies threats to recovery as soon as they occur. ReliableDR has zero footprint in production and requires no changes to applications. It is fully application-aware and operates at the IT Service level to test complete recovery processes in fenced virtual sandboxes. The certification cycle is aligned with business policy; tests can go from a cursory heartbeat check and
a web page access for a minor service, to complex queries and heavy transactions for critical production applications. Upon successful conclusion of tests, ReliableDR certifies the recovery point and catalogs it.
Not only are enterprise clouds vastly more dynamic than previous paradigms, but application complexity is also increasing geometrically, as the number of individual components that collaborate in the provision of each IT Service continues to increase. This growing interdependence fuels risk, as an individual component failure may have a severe knock-on or cascade effect on critical IT services. Moving Beyond Time-Consuming Legacy Tools Traditional backup is a 30-year old technology originally designed to copy blocks of data from expensive disk to cheap tape, and to keep track of their location. When backup was first created, application architectures were monolithic, deployed in mainframes with rigid and predictable configuration management systems. Applications and systems are significantly more complicated today. In cloud environments, a daily backup routine is simply inadequate to assure disaster recovery. Backups are very time consuming to recover from, and components get easily out of sync with one another, particularly when backup jobs fail or finish .
