Replacement of defective hard disks within 24 hours
If you want to replace a defective hard disk, just let us know. If your order is in the system before 12 noon and the hard drives are in stock, they will be replaced within 24 hours. Applies within the 3 year warranty for each TeraStation and LinkStation NVR sold in the EU. (Outside the EU it can take longer).
Hot-swap function increases data security
With the hot swap function, the TeraStation™ automatically switches off the defective hard disk even if one hard disk fails, so that it can be replaced safely without interrupting work or losing data.
Intuitive web management interface
The web interface has a dashboard that offers the user more effective views of system status, the ability to resize windows (even on the phone) and a more comfortable button layout.
Replication with TeraStation
By replication, a folder in two separate TeraStations™ is synchronized almost in real time. This only happens in one direction (not bi-directional) – from the source to the destination. This function can be set up in LAN and WAN. WAN setup includes remote connection via port forwarding and VPN setup.
Equipped with reliable NAS HDDs
This series is completely equipped with special NAS hard drives – for even more performance and reliability in RAID and continuous operation.
iSCSI target support
Works simultaneously as NAS and iSCSI target.
Including 11 licenses NovaBACKUP® Buffalo Edition software. NovaBACKUP® provides small and medium-sized companies that value the protection of their digital data with a complete data security solution in one package.
Allocation of disk quota
Hard disk quotas prevent the misuse of storage space by allocating appropriate amounts of storage to users.
