Has supported flexible multi-platform backups and improved over time
Regarding the effectiveness of Dell NetWorker in terms of role-based access controls, I have experience with it, but I find it somewhat lacking in flexibility as it offers limited features, and I would rate it around seven out of ten. It is not that there is something wrong with the role-based access controls in Dell NetWorker, but it lacks many permissions or roles to assign, providing options only for administrator or user. To improve Dell NetWorker for the next release, I recommend enhancing flexibility in the policy, allowing selection of multiple options within the same policy, and addressing issues like the DNS lookup dependency to make it more controllable from Dell NetWorker itself rather than relying on other applications. Looking forward, I would like to see improved policy features and a more enhanced GUI, as it is still slow.

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

"Technical support from Dell is excellent."
"The interface is user-friendly and can be used by the end-users."
"The best feature is the DR replication for us."
"Customer Service: It is great; EMC support is one of the best."
"Data domain is a good feature."
"If a centralized backup solution like Networker is deployed, the backup/recovery tasks will be on the responsibility of only one resource which is the backup administrator."
"If it's set up the right way, it's a stable product."
"The software’s best feature is data backup for any system."
"The dedupe and compression are pretty extreme. On disk, we're getting dedupe rates of up to 65 percent of data and compression of 34 percent. When you go to the cloud, it's more like 76 percent for dedupe and almost 50 percent for compression."
"Since we started to resell QoreStor, we have been using it internally; it's better than other backup solutions we have used or evaluated."
"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."
"Data deduplication and replication would be the top two features. The encryption and cloud tiering are also attractive for the future."
"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."
"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."
"Quest QoreStor definitely saved us money."
"We need revisions and safe backup so that it could be held up in court, but deduplication and compression are the main features why we have Quest QoreStor. That's where it really shines. I use ZFS and XFS at home, and Quest QoreStor is even better."
 

Cons

"It is a good product with some problems backing up virtual machines (slow restore)."
"It's complex in nature."
"They cannot perform an incremental backup using VSS technology for SharePoint or MS SQL Server."
"Dell EMC NetWorker has so many versions in a short span of time, which contain a lot of bugs that need to be fixed because each upgrade has its own issues."
"There should be more vendors incorporated into the solution."
"Users need to have specific knowledge of the product before they jump in and use it."
"I believe that the area of support could be improved. They don't appear to have an adequate number of staff members to assist us if we have any problems."
"The interface is the same, so when we are trying to troubleshoot the logs, it doesn't display properly."
"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 air gap feature is something I'd really like to see in QoreStor."
"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."
"Overall, I am happy with this solution, but a way to export configuration settings would be beneficial."
"The importance of support is significant to me. I was working for a service provider, and all of our customers had a Quest or warning. Sometimes the support really underperforms."
"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 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."
 

Pricing and Cost Advice

"I have a capacity-based license, but I don't know the exact cost of that license."
"If you purchase Avamar, NetWorker is free with Avamar, for one terabyte license capacity."
"The pricing of the solution is not the cheapest compared to other similar solutions. The Networker is available as a component of the Dell EMC Data Protection Suite package and it should have the ability to be purchased separately."
"It is excellent from the pricing point of view. It is free with Data Protection Suite. Similarly, when you purchase Avamar, Dell EMC NetWorker is free with one terabyte license capacity. Its price is very competitive."
"The price is a little on the high side, but it's reliable and provides a good service."
"On a scale from one to ten, where one is cheap and ten is expensive, I rate the solution's pricing an eight out of ten."
"You have to buy the deduplication software separately from the license."
"The tool is pricey."
"Its pricing model is very attractive. You have one price, and you get everything from QoreStor."
"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."
"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."
