Have supported critical environments despite room for improvement in legacy backup options
It is very efficient in cyber resilience. Deduplication, automation, and everything is very efficient. It is multi-cloud enabled and has broad protections. The software delivers flexible and efficient backup and recovery options through its cyber resiliency features. Dell PowerProtect Manager provides insights in managing backup processes. Its encryption mechanisms are very efficient, helping to secure sensitive data. Its integration with Dell EMC Data Domain is very good. It is easy to integrate with Data Domain. Multi-cloud options are enabled, and backup in cloud options exist in Dell Avamar.

Cost savings and efficient data management improve operations but support quality varies
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. I always had to get it escalated or ask for someone specifically because those other people would just read knowledge-based articles that I had already done myself. Quest QoreStor does not work with any backup software, server, or storage hardware. It has the hardware compatibility list, and you need a specific number of IOPS, so it needs to run on decent hardware at least to have enough input-output operations. Otherwise, the setup result will be canceled. I'm not too sure if there are still physical appliances, but when I first started, we had some customers with a physical Quest QoreStor appliance, and it would only run on certain hardware. It doesn't work with every backup program. For example, Veritas Backup Exec is incompatible, but Veeam is compatible, and V Ranger is compatible as well. I didn't even know that Quest QoreStor has any static AI and behavioral AI technologies.

Quotes from Members

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

Pros

"Stable and scalable backup and recovery software, with good technical support."
"Graphically, it's very user interactive. It's got a very nice interface."
"Its deduplication technologies are the best in the market, currently."
"We are talking about a complete end-to-end solution which comes with its own hardware storage to back up the data on tape-less."
"The setup is very easy."
"The backup is the solution's most valuable feature. It's very reliable."
"Quick incremental backups and product replication are the two highlights of the product. Once you capture a full backup, incrementals are pretty quick. It is fairly efficient from that perspective."
"Dell Avamar has a push upgrade feature that lets you simultaneously push updates to thousands of clients. I also found the self-service part of Dell Avamar helpful."
"Deduplication is the most valuable feature. It saves us a lot of space. When we back up 100 terabytes of data, after dedupe, it only uses maybe five to six terabytes for the disk space in QoreStor."
"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."
"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."
"Quest QoreStor is very stable compared to our previous solution."
"QoreStor has helped us to reduce our backup storage requirements on-premises. We've been using the same devices for quite a while, and so it lets us keep using them as opposed to having to rip out all that hardware and create a new on-prem solution. The advantage here is even if we had to retire the hardware tomorrow, the QoreStor part doesn't change. We just have to have additional hardware and put the solution back on whatever hardware we pick and it'll do the same thing."
"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

"The licensing model is not very flexible. Every time we upgrade our storage size, we need to upgrade the Avamar license."
"The performance takes up a lot of resources, unfortunately."
"Its ability to back up very large objects can be improved. In terms of new features, they can include the ability to use cloud services, like S3, more natively."
"Some customers need to back up to tape, but Avamar lacks support, so it costs a lot."
"The only concern is the cost."
"The recovery is a bit slow."
"Setup and deployment of this solution is complex and requires expert engineers."
"It's very slow to backup and store information. It has two consoles and an application which are more difficult to use than a solution like Veeam."
"They need to increase their maximum capacity. Other than that, they're doing a pretty good job."
"The management interface is in need of improvement. The graphical user interface (GUI) for the web management tools appears clunky, and not super intuitive."
"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 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."
"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."
"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 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."
 

Pricing and Cost Advice

"Dell Avamar is a moderately priced solution."
"It was approximately $70-80,000 when it was under support, but right now EMC has not been supporting this product for two years."
"It is very expensive. It's a trust based licensing. So that's an ethical challenge."
"The cost of the solution is very expensive."
"I'm not sure, but perhaps the pricing could be done better at the moment."
"Avamar's pricing is quite competitive compared to other vendors."
"It is easy to use."
"The solution is expensive."
"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."
"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."
