Using Rsync for NAS-to-NAS Backups on your ReadyNAS

By dbott | September 14, 2009

Using Rsync for NAS-to-NAS Backups

This document was originally written for the Infrant ReadyNAS 1000S, NV, 600, and X6 by the folks at Infrant Technologies (acquired by Netgear in 2007).  It  has been reproduced here, as it is still very useful for the current generation of ReadyNAS products (the Duo, NV+, 1100, NVX, Pro, 2100 and 3200).

You’ve heard it before, but it’s worth repeating—an organization’s most valuable asset is the data that comprises its information store. With ever increasing amounts of data, and the need to find an efficient method for ensuring its confidentiality, integrity, and availability, organizations often find themselves struggling with managing data stores.

The ReadyNAS product line (Duo, NV+, 1100, NVX, Pro, 2100 and 3200) of network attached storage devices provides a cost-effective way for organizations to share information without investing in expensive server-class hardware, bloated network operating systems, and seemingly endless client access licenses. Yet, they provide many of the same benefits as traditional file serving methods, including support for multiple sharing protocols as well as share-based, user-based, and domain-based security models. At the same time, because of their large data store capabilities, they need to be backed up as efficiently as possible.

In this guide, we’ll focus our attention on implementing NAS-to-NAS backups using Rsync, a native file synchronization service included with the ReadyNAS devices. In our presentation, you’ll discover methods for backing up NAS devices on a LAN, between subnets isolated from each other by a firewall, and across a WAN connection using Virtual Private Networking (VPN) technologies. Moreover, each method we’ll present builds on the previous one, so you can implement the appropriate backup strategy as your needs change.

    Can you do Rsync NAS to NAS backups using two RNP Pioneer boxes or one RNPP and one RNP Business class or do you need two RNP Business class boxes?

    I have a single RNPP box and it has been a great box for learning but I wonder if its limitations will be a problem

    Thanks,

    You should be able to use any of the ReadyNAS devices to create an rsync backup solution. The Business Edition units (Pro BE, NVX BE, 2100 and 3200) also support rsync-over-SSH that can keep your data from prying eyes.

    Otherwise, any ReadyNAS device will work.

    Here is the how-to for rsync-over-ssh:

    Thanks dbott for great manuals and walkthroughs! In the above guide you were using VPN, but in your comment to BigBearf your are mentioning “rsync-over-SSH”??? Shall I interpret this as SSH is something similar to VPN??? If so, does it mean that IF I have TWO ReadyNAS NVX, one at our office, and one at home, I can backup my “Office-NAS” to my “Home-NAS” using SSH and not having to invest in new routers capable of VPN????

    Yes, you can safely and securely backup the NAS using rsync-over-SSH without need for a VPN (SSH stands for “secure shell”). A router with built-in VPN capabilities would encrypt ALL traffic between home & office, where as using rsync-over-SSH on the NAS would only encrypt the backup traffic. The other benefit of a hardware-based VPN is that the encryption is performed by the router, rather than the NAS, which should generally provide better WAN performance and less CPU load on the NAS.

    Today I do have an NVX and thought that by buying a second one and place it in our house I would not be forced to buy a VPN router for both home and office. Have you any experience of this scheeme? That is, using to business NAS to do backups using rsync over SSH? I hope you can do the first session by having them side by side!!!

    At work, I use rsync (not over SSH) to backup a primary ReadyNAS 2100 to a couple of off-site units over our private VLAN. There’s a how-to here on configuring rsync-over-SSH with the ReadyNAS:

    Have you ever heard of a way to backup a NV+ to Amazon Cloud? S3… and if so, do you know the step by step… I also have cloudberry… like a FTP for Amazon.

    Sorry, no idea on how to do it. You may want to search the ReadyNAS forums: http://www.readynas.com/forum/
