Announcement
Nexsan announced Cloud Transfer for their Assureon product a little while ago. I recently had the chance to catch up with Gary Watson (Founder / CTO at Nexsan) and thought it would be worth covering the announcement here.
Assureon Refresher
Firstly, though, it might be helpful to look at what Assureon actually is. In short, it’s an on-premises storage archive that offers:
- Long term archive storage for fixed content files;
- Dependable file availability, with files being audited every 90 days;
- Unparalleled file integrity; and
- A “policy” system for protecting and stubbing files.
Notably, there is always a primary archive and a DR archive included in the price. No half-arsing it here – which is something that really appeals to me. Assureon also doesn’t have a “delete” key as such – files are only removed based on defined Retention Rules. This is great, assuming you set up your policies sensibly in the first place.
Assureon Cloud Transfer
Cloud Transfer provides the ability to move data between on-premises and cloud instances. The idea is that it will:
- Provide reliable and efficient cloud mobility of archived data between cloud server instances and between cloud vendors; and
- Optimise cloud storage and backup costs by offloading cold data to on-premises archive.
It’s being positioned as useful for clients who have a large unstructured data footprint on public cloud infrastructure and are looking to reduce their costs for storing data up there. There’s currently support for Amazon AWS and Microsoft Azure, with Google support coming in the near future.

There’s stub support for those applications that support. There’s also an optional NFS / SMB interface that can be configured in the cloud as an Assureon archiving target that caches hot files and stubs cold files. This is useful for those non-Windows applications that have a lot of unstructured data that could be moved to an archive.
Thoughts and Further Reading
The concept of dedicated archiving hardware and software bundles, particularly ones that live on-premises, might seem a little odd to some folks who spend a lot of time failing fast in the cloud. There are plenty of enterprises, however, that would benefit from the level of rigour that Nexsan have wrapped around the Assureon product. It’s my strong opinion that too many people still don’t understand the difference between backup and recovery and archive data. The idea that you need to take archive data and make it immutable (and available) for a long time has great appeal, particularly for organisations getting slammed with a whole lot of compliance legislation. Vendors have been talking about reducing primary storage use for years, but there seems to have been some pushback from companies not wanting to invest in these solutions. It’s possible that this was also a result of some kludgy implementations that struggled to keep up with the demands of the users. I can’t speak for the performance of the Assureon product, but I like the fact that it’s sold as a pair, and with a lot of the decision-making around protection taken away from the end user. As someone who worked in an organisation that liked to cut corners on this type of thing, it’s nice to see that.
But why would you want to store stuff on-premises? Isn’t everyone moving everything to the cloud? No, they’re not. I don’t imagine that this type of product is being pitched at people running entirely in public cloud. It’s more likely that, if you’re looking at this type of solution, you’re probably running a hybrid setup, and still have a footprint in a colocation facility somewhere. The benefit of this is that you can retain control over where your archived data is placed. Some would say that’s a bit of a pain, and an unnecessary expense, but people familiar with compliance will understand that business is all about a whole lot of wasted expense in order to make people feel good. But I digress. Like most on-premises solutions, the Assureon offering compares well with a public cloud solution on a $/GB basis, assuming you’ve got a lot of sunk costs in place already with your data centre presence.
The immutability story is also a pretty good one when you start to think about organisations that have been hit by ransomware in the last few years. That stuff might roll through your organisation like a hot knife through butter, but it won’t be able to do anything with your archive data – that stuff isn’t going anywhere. Combine that with one of those fancy next generation data protection solutions and you’re in reasonable shape.
In any case, I like what the Assureon product offers, and am looking forward to seeing Nexsan move beyond the Windows-only platform support that it currently offers.
