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

"The most valuable features of NetApp ONTAP are its data redundancy, performance, storage catering, snapshot technology, and NetApp Insight."

"It has the ability to bring up disaster recovery quickly."

"We over-allocate our aggregates and it still works, it's great, it's fun. We dedupe everywhere, we get huge savings. We went back and deduped the whole thing again, we could get more, so that's what we do. We go back and look to see if there's an option we can set and do it from the beginning, but still 13 terabytes, that's a lot of dedupe savings. Sometimes we get 50% or more in our savings, so we love dedupe."

"The product is good at deduplication. Also, the new automation feature is good, as it saves us a lot of time."

"The stability of our ONTAP system has been awesome over the last four to five years, particularly with the software. The controls have been excellent as well. We recently went through a view of all of our systems and found a number of them had been up, over three years without any sort of reboots or downtime. We have been very happy with the stability of the systems."

"It has been amazingly easy for us to use."

"What I appreciate the most about the product is its resiliency."

"We see it drastically improving our organization, as we are trying to move away from Fibre Channel and SolidFire with iSCSI will change a lot going forward in the organization."

More NetApp ONTAP pros

"It integrates with various backup software solutions, which makes it compatible with existing backup workflows and processes."

"If storage costs are a problem, whether on-premises or cloud, QoreStor is worth a serious look."

"I would rate QoreStor a ten out of ten for what it offers for the price."

"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."

"Since we started to resell QoreStor, we have been using it internally; it's better than other backup solutions we have used or evaluated."

"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."

"QoreStor has helped to reduce our backup storage requirements on-premise by at least 90%."

"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."

More QoreStor pros

Cons

"NetApp ONTAP has several limitations that we encounter, primarily related to large enterprise clients. They do not affect small clients that NetApp may have. While these limitations are clearly described, some issues require us to develop workarounds."

"They could lower prices so my management doesn't complain about cost."

"The GUI of NetApp ONTAP is an area with certain shortcomings that need to be considered for improvement."

"I would like to have deduplication and SSD features in the product."

"Some of their products have been really good for us, on certain versions. We've run into a bunch of verts, though. That's NetApp's word for their bugs. Stability has been the main complaint that I've had with the product. Because it's so feature-rich and has so much software related to it, it does come with a decent amount of bugs so we do a lot of upgrades to patch bugs."

"While the data efficiency features are great, I want to see more efficiency and compression type of technology."

"The price could be lower."

"There is room for improvement in the stability. They have been trying to become simpler, and as a result, there have been road bumps along the way. I have personally experienced this."

More NetApp ONTAP cons

"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 setup of the software is definitely not the easiest thing in the world."

"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."

"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."

"The management interface is in need of improvement. The graphical user interface (GUI) for the web management tools appears clunky, and not super intuitive."

"The air gap feature is something I'd really like to see in QoreStor."

"The ransomware protection of QoreStor could use improvement."

"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."

More QoreStor cons

Pricing and Cost Advice

"We received a super deal for our new machine, so we were happy with the price."

"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."

"The pricing for NetApp ONTAP is moderate."

"In the past, you didn't have to buy separate products. They were mostly included with the purchase. In the end, it's more expensive to buy it separate than together. If you are going to need it, one package at the beginning is cheaper."

"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."

"Because of the dedupe technologies and Data ONTAP servers, we have saved 20% on hardware. This is a lot of money for us."

"The data compression and deduplication have kept us from buying more disks these past three years."

"I rate NetApp ONTAP's pricing a seven out of ten."

More NetApp ONTAP pricing and cost advice

"Its pricing model is very attractive. You have one price, and you get everything from QoreStor."

"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 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."

"The cost is per terabyte, and overall, the cost was reasonable when compared to some competitors."
