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.
10GbE Compatible: Ready for future data growth
While having a growth in data and file sizes, you can now benefit greatly from lower-costing 10GbE products. 10GbE-compatible devices and category 6A (Cat 6a) or higher-rated cables allow improvements to office productivity by eliminating network bottlenecks and shortening data backup times.
No 6A cabling in your office? No problem! WS5020 is compatible with IEEE802.3bz and it gives you faster data transfer speeds even with your CAT 5e environment.
With Buffalo's BS-MP20 business switch, users can easily develop faster data transfer environments. (More about 10GbE)
