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.

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

"It is one of the best solutions for backing up Oracle and other servers."
"The solution scales well."
"The solution is very stable and the performance is reliable."
"The backup and recovery speed is very fast."
"The function I find most valuable in Dell Avamar is its ability to take differential backups for users. This feature is very effective for both backup and restore operations. We've had multiple cases where we needed to restore files directly from Avamar, and it worked perfectly. The Delta feature, which captures changes in user files, is particularly useful."
"Dell EMC Avamar is easy to work with and is user-friendly."
"The solution is very stable."
"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."
"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."
"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."
"It integrates with various backup software solutions, which makes it compatible with existing backup workflows and processes."
"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."
"I would rate QoreStor a ten out of ten for what it offers for the price."
"If storage costs are a problem, whether on-premises or cloud, QoreStor is worth a serious look."
"Data deduplication and replication would be the top two features. The encryption and cloud tiering are also attractive for the future."
 

Cons

"The licensing price must be reduced."
"The interface has room for improvement. It's not ideal right now."
"Desktop-laptop backups and backup over the WAN needs lot of improvisation. For DTLT there must be a provision to push agents from the management console."
"Like any other company, many of the support calls go to places on the other side of the world. It is sometimes difficult to understand them."
"Reporting in Dell Avamar needs improvement. The current reporting tool is very basic, and you have to dig deep into each function to get the information you need. For example, getting the status of failed and succeeded backups is very difficult in Avamar compared to Veeam. As for additional functionality, I would suggest improving WAN optimization. It's very important for getting offline or off-site backups. It should also include a tool to check for ransomware which would be beneficial. If a backup is vulnerable to ransomware, there should be a way to detect it, like using ARR rules to ensure your backup is ransomware-free. I haven't had any experience integrating Dell Avamar with AI solutions. It’s also a good point that Avamar doesn't offer such integrations, which is an area where Dell could improve."
"Dell hasn't done a good job at handling these upgrades, or the way EMC used to handle them."
"There are instances where backups fail on certain applications, which is an area that could be improved."
"Compared with Cohesity or Rubrik, which have some continuous data protection for backup and replication, this solution tends to lack in this area."
"The setup of the software is definitely not the easiest thing in the world."
"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."
"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 air gap feature is something I'd really like to see in QoreStor."
"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."
"Support is one point of improvement for Quest QoreStor. Support is sometimes not adequate."
"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."
"Overall, I am happy with this solution, but a way to export configuration settings would be beneficial."
 

Pricing and Cost Advice

"It was very expensive before, but after integrating it with Dell EMC Avamar Data Protection suite licensing, we are getting better discounts."
"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 expensive. Its cost is the main thing."
"Dell Avamar, including its virtual add-ons and cloud-based offerings, is cheaper than other solutions, but in the end, the price still depends on your use case. Price-wise, I'm rating Dell Avamar as six out of ten."
"The solution is expensive."
"Licensing fees are paid annually."
"It is expensive. The maintenance comes with it for five years. So, you buy the whole thing for five years, and your maintenance is included with it, but it's a big chunk of change upfront. We like capital expenses because we can CapEx them. We pay once every five years, so we spend a big chunk of change. You'd have to divide that out by the five years to come up with how much it costs. It's just about three-quarters of a million dollars for five years."
"The cost is per terabyte, and overall, the cost was reasonable when compared to some competitors."
"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."
"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."
