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

"Scheduling is valuable. It does a good job of backing up, and it does a good job of restoring. Nobody has got a problem with that. The agents are well supported."

"All the features in the system are highly valuable."

"I always recommend Dell Avamar to our enterprise customers because the product is costly, and enterprise customers can afford it."

"Effective in protecting the virtualization system and end points."

"Dell EMC Avamar is easy to work with and is user-friendly."

"The stability is okay."

"I like Dell EMC Avamar's compression of data."

"We have seen huge data reduction and data deduplication and compression, which is very cost-effective and cost-reducing for the company."

More Dell Avamar pros

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

"Quest QoreStor definitely saved us money."

"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."

"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."

"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."

"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."

More QoreStor pros

Cons

"If there is a need to move the data from one backup solution to another, it might be difficult since there is no option for a straightforward migration."

"Avamar is still competitive because of the way we have deployed it, but we need to diversify and shift away from specific technologies. In addition to hypervisors, virtual machines, and bare metal servers, our customers need protection for Microsoft 365, SaaS, and the public cloud, so we need other technologies in the business to cater to those customers' needs. Those are the enhancements we would want from the Avamar platform, but that's not likely to happen. Dell has PowerProtect and Apex backup services. There are other Dell solutions that we'll use to fulfill our customers' requirements."

"The bare-metal restores could be improved."

"Some customers need to back up to tape, but Avamar lacks support, so it costs a lot."

"More integration would be helpful, as well as the addition of more applications."

"Compared with Cohesity or Rubrik, which have some continuous data protection for backup and replication, this solution tends to lack in this area."

"Backup image browse times should be faster."

"When you get down to doing certain things, such as somebody wants a particular file restored, the process by which you do that is stupid. You kind of have to know exactly where to look for in order to find it. Even on older backup products that I've used, I didn't have that kind of problem. If we were looking for a file with a particular kind of a name, the solution would find that file anywhere irrespective of where it resides within the backup system. So, we didn't have to know the name of the specific server, the specific timeframe, almost all the characters of the file name, and all kinds of data in order to find a file. In Avamar, we got to know these details. We've gone around and around with them on that, and their attitude seems to be that it is working just fine. There is nothing for them to improve. The organizational system of other products that I'm working with, such as Zerto and Cohesity, seems to be centered around the tasks that you would most commonly do and want to do, as opposed to we've laid it out in a really neat technical hierarchy."

More Dell Avamar cons

"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."

"The ransomware protection of QoreStor could use improvement."

"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."

"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."

"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."

"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."

"Support is one point of improvement for Quest QoreStor. Support is sometimes not adequate."

More QoreStor cons

Pricing and Cost Advice

"It might not be beneficial to smaller businesses due to its high cost."

"Dell Avamar is expensive."

"The price is fair."

"Licensing was generally on a per VM or terabyte basis. They changed their licensing model a couple of times and turned it into socket-based licensing, which is an improvement in their licensing model."

"The solution is not expensive for the value one gets."

"It is expensive. Its cost is the main thing."

"It's an expensive tool"

"The cost of the solution is very expensive."

More Dell Avamar pricing and cost advice

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

"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."

"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."
