Disaster can strike at any minute, which is why it is essential to have a comprehensive plan for business continuity and disaster recovery (BC/DR). This device can serve as a subscription-free BDR solution, with DFS replication and Storage Replica to replicate data across servers and Shadow Copy to create image backups. You can also set up the NAS as an offline replication backup location and bypass cloud storage costs. In a pinch, you can use Hyper-V to create a virtual machine (VM) as a temporary solution, or create an archive of Azure VMs for redundancy.

 

This device is included in NovaBACKUP’s BDR bundle, available in a monthly subscription. Click here to learn more.
