Windows server 2012 Seminar 3: Hyper-V replica

  1. 1. Microsoft Windows Server 2012 Seminar: Disaster Recovery met Hyper-V replication in Windows Server 2012 Bent u op zoek naar een Disaster Recovery (DR) oplossing zonder de hoge kosten zoals bij SAN replication komen kijken? Dan is Hyper-V Replica iets voor u. Deze nieuwe feature is bedoeld voor klein- en midden-MKB. Het is een storage log asynchrone opslagtechniek waarbij iedere 5 minuten alle wijzigingen van een Virtual Machine worden gerepliceerd naar de Disaster Recovery locatie. Hiermee heeft u een goedkope Disaster Recovery oplossing waarmee hooguit 5 minuten aan data verloren gaan. U kunt deze techniek ook gebruiken wanneer u geen Disaster Recovery locatie heeft, want de replica kan ook naar de public cloud!!
