Senior Storage Engineer at Shell
Data management and availability improve operations, but cost and support need attention
For snapshots, there should be something similar to a recycle bin. When someone mistakenly deletes a snapshot, it should be stored for about two days before disappearing from the system. Regarding storage optimization, when purchasing a 10 terabyte disk, after formatting, you can only use approximately 8 terabytes. They should improve this so users can utilize 90% instead of 80% of the disk space. The support response needs improvement, especially for P1 cases. When critical cases are raised, they should ensure they call the customer and follow up properly. Comparing NetApp ONTAP to other solutions such as EMC, the cost of contract renewals and warranties is relatively expensive. They should extend their renewal window beyond the current six months to one year options. A longer warranty period of two years for new systems, controllers, or filers would be beneficial. Overall, they should reduce subscription costs for businesses.

Backup storage has shrunk dramatically with deduplication but still needs stronger security options
The air gap feature is something I'd really like to see in QoreStor. There's no native air gap capability right now, and for security-conscious environments, that's a gap. The configuration export is also limited in QoreStor. If you want to document your setup or migrate configuration to a new instance, it requires more manual work than it should.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Overall, for us, it's the stability, it has a solid infrastructure. It's easy to use, easy to rack and configure and start utilizing really quickly. It's been very stable, it works great, and it does everything we would want it to do."
"The best features of NetApp ONTAP include its good UI."
"The interface is very user-friendly. There are new features, including analytics that provide insights when you log in. The dashboard is very intuitive."
"The deduplication is valuable."
"NetApp's technical support and proven stability are a lot better than them."
"In the three years that we have been using the solution, we have not encountered any problems with it and found it to work really well."
"With the NetApp Data ONTAP Cluster, we get some features that are particularly helpful. For example, we can always add to and remove nodes from the cluster. The ability to move volumes online from the storage side, from one aggregate to another aggregate, or from one node to another node, keeps up the performance which helps us a lot."
"The solution is very easy to configure."
"The features we use for the data deduplication are nice because we're able to back up a much larger amount of data, yet it doesn't necessarily take up that much data on the devices."
"Since we started to resell QoreStor, we have been using it internally; it's better than other backup solutions we have used or evaluated."
"I would rate QoreStor a ten out of ten for what it offers for the price."
"Quest QoreStor is very stable compared to our previous solution."
"Overall, it simplifies the management of backup and gives me a more secure feeling that my data is going to be available if I need to retrieve it."
"The extreme compression of data is a big thing for us. We were looking for an online backup solution, and QoreStor is very good in terms of data compression. It helps us minimize the required storage in the Blob Storage environment."
"Not having to be onsite to swap tapes on a daily, weekly, or monthly basis, alone, has really paid for its usage through the savings in time."
"This software solution can be installed on many different types of hardware, which makes it very flexible. We can run it on virtual machines or virtual servers, providing convenience for solutions of varying sizes, from small to large."
 

Cons

"We are always looking for more security enhancements and ways to continue to provide security encryption, whether it's data in rest or security in transit. We would also like to have more enhanced encryption beyond the regular TLS and 256-bit."
"I would like more diagnostic generation. Right now, it's a pain to go into the controller and do a full diagnostic and export."
"NetApp ONTAP could be improved with additional features to help handle the backup of more than 10 to 15 devices simultaneously."
"ONTAP tech support needs some improvement, but it has improved quite a bit."
"If you do the initial setup manually, it is a bit difficult for someone who doesn't know."
"Because most of us were new to the product, the initial setup was a bit cumbersome. Once we were trained, it was fine."
"File level restoration could be improved."
"Technical support is good but they can take some time on critical problems."
"In terms of improvement, we would like to have an Air Gap feature to prevent a virus from attaching to something. So that when we don't do a backup, we want the QoreStor to stay offline. It would be a nice feature to have."
"Overall, I am happy with this solution, but a way to export configuration settings would be beneficial."
"There can be some kind of monitoring solutions to alert users to issues with the appliance or software, making it easy for customers to monitor their systems in the field."
"The setup of the software is definitely not the easiest thing. I worked a lot with Quest engineers, especially in the early days when we were first testing it and trying it out. I actually had some of the developers working with us at one point because they were going through these point releases, and I was having trouble getting it to work in this S3-compatible situation. We got it all working eventually, but setup is definitely not the easiest thing in the world."
"They could improve on support a little bit. We have not had to engage their support much, but when we do have issues, it can take longer to get things resolved."
"The installation could use improvement. The initial installation was a little touchy and it's not really user-installable. You have to have a connection to support to install."
"The management interface is in need of improvement. The graphical user interface (GUI) for the web management tools appears clunky, and not super intuitive."
"Overall, I am happy with this solution, but a way to export configuration settings would be beneficial. After everything is set up and configured, there should be a way to export the configuration. In case something happens to the QoreStor server, and we need to reinstall and configure everything, being able to import the configuration would be helpful. This feature does not currently exist."
 

Pricing and Cost Advice

"Our cost per IOP is three to four dollars, but we have a hybrid solution. Therefore, we have SSD and spinning disk running together."
"The price could be a little bit cheaper, but you get what you pay for."
"We have seen ROI, especially with the deduplication. We have a high ratio of deduplication and are way past 70 percent of our VDI, as we have almost 400TBs on our VDI. We have been able to save at least a quarter of a petabyte of space."
"The solution has helped us reduce the overall cost of storage by doing an OPEX agreement with NetApp, we are paying based on utilization. Instead of fronting 30 petabytes worth of storage, we are paying for what we're using."
"There are two consumption methods: pay as you go and subscription. Pay as you go... is a little expensive but worth it."
"At first, it's expensive. Once you start using it, it's not that expensive. When you see all the benefits, it's acceptable. It could always be better, but you get what you pay for."
"It helps us save money using compression and deduplication."
"We have a wholesale contract with NetApp. We also have NetApp ONTAP On-Demand activation for certain things. We also have some preferential pricing for licenses. The licensing that I see here doesn't apply to other clients in the field. NetApp is expensive, but so are the competitors, making it hard to ascertain precise retail value. However, based on my perspective, NetApp pricing appears competitive."
"The pricing is good. It is competitive for a managed services provider. I like the ability to pay by the terabyte, allowing for an incremental cost that we and our customers can afford, so the solution grows with the customer."
"Quest QoreStor's pricing is affordable. We evaluated Veeam, a well-known company for backup solutions, but found their pricing to be quite high. Veeam's price was almost double. For us, Quest QoreStor is very affordable."
"The cost is per terabyte, and overall, the cost was reasonable when compared to some competitors."
"Its pricing model is very attractive. You have one price, and you get everything from QoreStor."
