Quotes From Members
We asked business professionals to review the solutions they use.
Here are some excerpts of what they said:
Pros
"With Nasuni Management Console (NMC), we get a single, centralized view of our entire internal structure and data center structure. This is very important because this caters to remote locations. One of the main care center teams is dependent on this solution. As it is directly connected to customers for the calls that they receive and troubleshoot, they can then help customers out in case they are not able to place an order.""The solution gives us a breakdown and summary of every resource and each volume within every resource. It tells us the code within a given volume, so I can go in there and look at the size of the files that are stored there. Nasuni gives me the big picture and allows me to connect things like Power BI to any endpoint. I can take that tabular information from Nasuni and look at it in a graph.""Nasuni has the capability of taking a snapshot every five minutes. If a user has accidentally deleted their data, we can recover it from the snapshot and provide the latest data to the user. It's a really great feature, one that is not provided by other vendors.""The biggest and most impressive thing for us is the operational recovery (OR) and disaster recovery (DR) capabilities that Nasuni has. If a filer goes down, or an ESX server goes down, then we can quickly recover.""I like the unlimited snapshotting.""Nasuni has helped to eliminate on-premises infrastructure. We were using about eight to 10 different types of vendors or small storage boxes for provisioning and shared access for users. We got rid of all those. That has eliminated operational overhead and footprint at our data center. We don't have to worry about any hardware or monitoring particular devices, and hundreds of devices have been decommissioned. Now, for provisioning, everything is on Nasuni. I assume this has made a big difference in costs.""The nice thing about Nasuni storage is that it is immutable. This means the data is only written once. So, you never modify the files. When you write a file out to the storage, it doesn't modify it when you change it. The technology knows how to figure out what the difference is between the original file write and what the changes are. Therefore, it only saves the changes.""The snapshot functionality and the unified file system are definitely the most valuable features for us. The UFS allows everybody across the organization to see the exact same data at the same time, instead of having different file servers with different structures on them, and that's mission-critical. We have different branches throughout our organization that have to act on that data."

"Zerto is extremely easy to use. You set it and forget it.""The return to operations is the most valuable feature because it decreases the amount of time it takes us to recover.""There are two things that are keeping us with the solution: 1. It does a very good job of keeping the data in sync at all times. 2. In the event of a failover or in the event of a contingency, we are able to retrieve the data very quickly without any issues.""The communication between the VM and the secondary data center is the most valuable feature.""We are doing continuous data protection. It works flawlessly. Our recovery points are measured in seconds. We have all these "baby snapshots" throughout the course of the day, so we can roll a VM back to any point in time, spin it up, and away we go. We're actively using that. It works great.""The most valuable feature for us is accelerating cloud adoption, as it helps provide greater speed for disaster recovery. Ultimately, this saves us time, as well as resources.""The initial setup was very straightforward and easy. We were able to start replication within minutes of the initial setup.""There wasn't anything in place that compares to what we're getting from Zerto. Before Zerto, we didn't have a proper disaster recovery program or application in place. We had a simple backup solution where we could back up our data every 24 hours. So we went from that to being able to recover full systems within a matter of minutes. With Zerto, if we do have an event or disaster, we know that we can recover from that much quicker than we were able to before."

Cons
"The speed at which new files are created is something that could be improved. For example, if you create a new file in another country, I won't see it for between 10 and 15 minutes.""One area that we've recently spoken to Nasuni about is single sign-on. Another is integrating Nasuni with Azure Active Directory. In our particular case, that would allow for third-party consultants to access our Azure Active Directory environment as opposed to coming to our on-premises environment.""I would like to see them improve their tools in regards to accessing data using smartphones, tablets, and iPads. I think the Nasuni app could be improved to make access to the data cleaner and more efficient.""When we have to rebuild a filer or put a new one at a site, one of the things that I would like to be able to do is just repoint the data from Azure to it. As it is now, you need to copy it using a method like Robocopy.""Nasuni does not support different retention policies within the same volume, so you have to keep creating volumes for retention policies. When you create a new volume, it means you're starting from zero all over again. You can't move data between two volumes. You have to move them from your physical device to Nasuni or your cloud device to Nasuni.""It is difficult to configure Nasuni. Adding a filer is an easy task, but deciding where to add them, how many to add, and what size to add takes a lot of time. I have to analyze my existing storage to understand how many users are going to access which folders. I have to design the Nasuni architecture accordingly.""As administrators, we are used to having control equal to managing an on-prem device. In terms of log analysis and other things we want to do, Nasuni has some limitations limitation on what you do on the Nasuni. Nasuni could add some features to the GUI that make administration a little easier. It's tough when I have to move from one filter to another because there is no way to search it. We have to scroll up and down to find the name of it.""I would like to see Nasuni provide the ability to mirror a Nasuni appliance from one site to another. They could maybe have a standby appliance that is mirrored in a different location for disaster recovery purposes. We can recover if data and a Filer are lost because of a possible ransomware event, but even that takes time to recover. If we had the ability to have a mirrored appliance, we could flip over to that mirrored device and resume instantly rather than repopulate the local appliance with data from the snapshot history in the cloud. This is another feature that we would really like to see, if possible."

More Nasuni Cons →

"The licensing is confusing and complicated.""Another thing that would help would be a recommender, or some type of tool that says, 'Hey, you're not conforming to best practices.' It would do a conformance or compliance check to tell you if your VPGs are set up according to best practices and whether your Zerto clusters are set up optimally. It would see if you have HA enabled and whether your alerting is turned on.""They are not cheap. They are more expensive than others.""It is crucial for Zerto to collaborate closely with VMware in order to promptly test updates.""We did look at the long-term retention backup feature of Zerto a few years ago, and at that time, it was limited. I can't say what it is right now, but at the time, its functionality was limited in terms of basically where we could save it and how we could save it. Offsite air gapping our backups is important to us to help protect against ransomware, and at the time, it couldn't do that. That would be one area that would be important before we consider using the long-term retention again. I haven't looked at it recently, and they may have addressed this in the meantime, but if not, this would be an area of improvement.""We had some issues with replication, especially on Linux, but we have already resolved them.""When it comes to a solution, one of the things the management wants is to standardize platforms. That's why when Rubrik came out with their solution, they wanted to look at it. For instance, if you have multiple technologies, you're going to need admins to manage all those different ones. I would like Zerto to be something that fits all our needs, including the backup that Rubrik provides, but I understand that not all solutions can be that way.""We do have some sites that are very low-bandwidth sites. Zerto is able to set throttling in the solution, but the throttling is set at a site-wide level. In those instances that have very low bandwidth, I can't reduce the throttling on that site. It would be nice if there were a way to control the throttling by the protection group for a specific workload."

Pricing and Cost Advice
  • "It is around $850 per terabyte per year. Any additional costs that you would incur are for the local caching devices that you'll need to access Nasuni. You kind of provide your own virtual machines or compute to access the data. You also pay for the object storage. So, there are three parts to it. There is the Nasuni license per terabyte. You would also pay for the actual object storage in the cloud, and then you would pay for virtual machines to access the storage."
  • "The pricing is on par with everybody else, and fair."
  • "The cost is based on the capacity, which is approximately $100 USD per terabyte."
  • "It has a license fee as well as hardware costs, which we would incur if we want to use Nasuni Cloud Storage Gateway for upgrades."
  • "I would not say it is economically priced, but it is affordable. If you can afford to pay for it, it is worth the money, but it is definitely not overpriced. It is priced about where it needs to be in the market. We were satisfied with the way they did their licensing and how they handled it. I believe they actually license by data size. It is based on how much data is being held on the machine and replicated, and that's completely understandable. So, for us, their pricing was as expected and affordable."
  • "Our agreement is set up such that we pay annually per terabyte, and we buy a chunk of it at a time. Then if we run out of space, we go back to them and buy another chunk."
  • "The cost of licensing is negotiated and billed annually per terabyte."
  • "There are annual costs that we pay for maintaining all of the snapshot history in the cloud. That is the primary cost that we pay. We occasionally buy newer Nasuni appliances or deploy them to new offices when the need occurs. That capital equipment expenses is less than the cost of buying new file storage systems. For the most part, you are trading a CapEx cost of storage equipment for an OpEx cost for management of all the snapshot data in the cloud."
  • More Nasuni Pricing and Cost Advice →

  • "Pricing depends on your future growth. Start small and then scale up."
  • "Zerto’s licensing model has changed a bit over the last year and they are in alignment with others. It is pretty simple and more economical."
  • "Licensing is based on the number of VMs to replicate. The first thing should be to get the number of VMs to replicate based on your business needs."
  • "Licensing is VM based so you can buy packages or single VM. Price is not low but the power of application is high, so you will get your money back."
  • "It's a little bit expensive."
  • "We believe the pricing, setup costs, and licensing are easy to understand. The pricing seems very reasonable."
  • "The solution is very cost-effective and very easy to set-up but does not compromise on features."
  • "While we find the twenty-five VM license somewhat inflexible, the actual setup costs are minimal as the product is so easy to install."

    Overview

    Nasuni is a file data services enterprise focused on assisting firms with their digital transformation, global expansion, and information awareness. The Nasuni File Data Platform is a suite of cloud-based services designed to enhance user productivity, ensure business continuity, provide data intelligence, offer cloud options, and simplify global infrastructure. This platform and its auxiliary services are projected to replace conventional file infrastructure such as network attached storage (NAS), backup, and Disaster Recovery (DR), with an expandable cloud-scale solution. By storing file data in scalable cloud object storage from multiple providers, Nasuni positions itself as a cloud-native alternative for traditional NAS and file server infrastructure. Based in Boston, Massachusetts, USA, Nasuni serves sectors like manufacturing, construction, technology, oil and gas, financial services, and public sector worldwide, offering its services in more than 70 countries.


    Reviews from Real Users

    James J., IT Manager at a marketing services firm, says Nasuni’s management dashboard is helpful because he's able to view all of the different filers at once rather than check each one of them individually. He values the software’s security, reliability, good performance, helpful alerting, and responsive support.

    According to a Server Engineering Services Lead at a mining and metals company, Nasuni offers good OR and DR capabilities, performs well, offers data security, and continuous file versioning helps recover from hardware failures.

    The Managing Director of IT at a construction company appreciates Nasuni because it eliminates a lot of work that was previously done when managing backing up and restoring data files.

    Zerto, a Hewlett Packard Enterprise company, specializes in data protection and empowers customers to run a business by simplifying the protection, disaster recovery, and mobility of on-premises and cloud applications. Zerto uses advanced hybrid cloud IT technologies to recover and protect business-critical applications in on-premises and cloud environments, enabling them to deliver continuous service without compromising security. Zerto’s foundation is based on continual data protection (CDP) technology. Users can benefit from a single, unified, and automated recovery and data management experience across all virtualized or container-based workloads.

    Zerto's native clustering technology creates a resilient, fault-tolerant system that automates recovery of critical virtual machines while supporting software updates, new OS releases, and upgrades. With native clustering, a creation, migration, or deletion of a virtual machine is automatically replicated to all nodes in the cluster. This creates an automated failover and availability solution with the features of high-end dedicated servers running at a fraction of the cost.

    Zerto Features

    Zerto has many valuable key features. Some of the most useful ones include:

    • Continuous data security
      • Continuous replication
      • The industry's lowest RPOs and fastest RTOs
      • App and database protection and recovery on a granular level
    • Agility across hybrid and multi-cloud
      • Protection between clouds
      • Simple on-premises to cloud migration
      • User-friendly native cloud services
    • Simple to scale
      • Automation and orchestration are built-in
      • Cross-platform, multi-site analytics
      • Unified experience regardless of cloud
    • Software-based
      • Hardware, hypervisor, and cloud are all independent
      • No physical appliances
      • Future-proof

    Zerto Benefits

    • Robust disaster recovery: Continuous data protection enables recovery of entire clusters, multi-VM applications, or even a single server with the lowest RPOs and fastest RTOs. Zerto allows users to safeguard, manage, and recover all of their key digital assets, whether they’re recovering to a secondary location, the public cloud, or a managed service provider.
    • Constant backup: Instead of making backups every 12 or 24 hours, Zerto creates backups every 5-15 seconds. Zerto backup has no impact on production and eliminates the burden of micromanaging backup windows by using CDP instead of snapshots. Its backup provides immediate recovery of data, folders, or virtual machines (VMs) that are only seconds behind the original, which is a simple approach to completely avoid ransomware or erase inadvertent deletions.
    • Strong long-term retention: Send data to the cloud or a purpose-built storage appliance of your choice for months or years of retention. These long-term copies can be made from local backups or DR replicas, and they can be kept wherever is most convenient for your company. Its powerful indexing and search makes discovering and restoring data simple. For data you want to maintain but only use infrequently, use cost-effective cloud tiering to shift LTR copies from hot to cold to deep-freeze storage.

    Reviews from Real Users

    Zerto stands out among its competitors for a number of reasons. Two major ones are its disaster recovery abilities and its ease of use. PeerSpot users take note of the advantages of these features in their reviews:

    Justin C., Director of IT at Arnott Inc. writes of the solution, “If we had to deal with a ransomware event, Zerto would be one of the first things I would use, because it is going to be the fastest to restore data to a certain point. If there were a fire in our building, Zerto would be a big thing too, because we would shut down everything that's in our building… It's definitely going to be one of our prevalent DRBC layers of protection."

    Brad W., Vice President of Information Technology at a financial services firm, notes, “The file restoration is very helpful. They've improved it over the years to make it a lot more user-friendly and easy to do, which I appreciate. So, we use that quite a bit. The failover process is quite simple and intuitive. Even the configuration and setup are pretty easy to do.”
