If you want the best backup features then look no further as the NVX is stuffed with them. First up are snapshots, which take point-in-time copies of volumes and can be scheduled to run regularly. The NVX can manage multiple backup jobs itself where it can secure data stored locally or remotely on another share and copy it to a local or remote location and this includes other ReadyNAS appliances.
You get three USB ports for use with external storage devices and printers and the front port has a backup button alongside it. If you've defined backup jobs on the appliance and assigned them to the button then pressing it will run these in sequence. If not, then it will copy the contents of a predefined folder on the appliance to the attached device.
The NTI Shadow software provided with the NV+ gets replaced by a three-user copy of Memeo's Backup Premium but this is for workstations only and will not install on Windows server systems. It functions in the same manner as NTI Shadow as it uses a background task to monitor selected drives and folders and once a full backup has occurred, it secures files as they are modified or newly created.
With the NVX, Netgear introduces the Vault - an online backup service handled by ElephantDrive. Once you've enabled the service on the appliance you can create an account from the Vault web portal and set up backup jobs to copy data from selected shares to the Vault data centre.
It's very simple to use and we created a job to constantly monitor the Backup share on the appliance. Once a full backup had finished we dropped some more files into this folder and after a few seconds they were automatically copied to the Vault. Alternatively, you can create backup jobs for different shares and run them at daily, weekly or monthly intervals.
Usefully, the off-site data can be accessed from any location over the Internet so if your NVX goes belly-up or is nicked you can still get your data back. A search facility is provided in the portal and once you've made your restore selections you can copy them back to a destination of your choice.
Having used an NV+ in the office for a couple of years now, we can say the NVX introduces some welcome new features. Performance sees a big boost and small businesses will appreciate the wealth of backup features and particularly the reasonably priced off-site Vault option.
