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

"This is a solution that I recommend; it is a good product, it's stable, it is easy to deploy, and the visibility of the backup and restore is good."

"Customer Service: Very good."

"Stable and scalable backup and recovery software, with good technical support."

"The stability of Dell EMC Avamar is very good."

"We sell Avamar with Data Domain. Data Domain and Avamar work really well together and their compression ratios are very high compared to Veeam, Commvault, and all the other backup software on the market."

"Avamar has long been the best in its class, but that's changing as new solutions emerge. However, Dell has traditionally been a leader in deduplication and compression. Avamar enabled us to shift data from on-premise local appliances to data centers and multi-tenant infrastructure. That's a powerful feature. because customers can back up to the cloud without upgrading o high-capacity links or congesting their backups."

"I found the most valuable features of Dell Avamar are the user-friendly interface and ease to use, as our clients have administered this software without additional training and the training materials have been very helpful for installation, troubleshooting, and upgrading."

"It's stable and offers good performance."

More Dell Avamar pros

"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."

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

"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."

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

"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."

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

More QoreStor pros

Cons

"The bare-metal restores could be improved."

"The client caches and deduplication system have a few problems."

"What would make Dell Avamar better is if it can do faster backups because right now, PowerProtect Data Manager is better in this area with its new UI and a new way to implement backups."

"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."

"We'd like to see something that could also work with Unix servers and physical servers to have a unified solution that works with everything."

"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 solution could be a bit easier to use in the sense that they need to make it simpler to backup products and restore items."

"I want to see a more user-friendly and administrator-friendly Dell Avamar. The solution also needs a better UI and dashboard."

More Dell Avamar cons

"They need to increase their maximum capacity. Other than that, they're doing a pretty good job."

"The ransomware protection of QoreStor could use improvement."

"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."

"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."

"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 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."

"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

"I'm not sure, but perhaps the pricing could be done better at the moment."

"Its licensing is weird. It is not just the licenses; we also purchase hardware. With most software products, such as Veeam, Commvault, and Data Protector, there is no hardware purchase at the same time. Because Avamar and Data Domain are tied together, they have an integrated pipe. You can separate them, but basically, they're designed to work as a couple. Because the Data Domain backend is designed to do dedupe and compression, we get 60:1. When you count it, you count it as a straight compression, but of course, that's with dedupe and some other stuff. You have to buy the hardware, the licensing, and the software at the same time. So, it's not just software."

"The solution is expensive."

"This solution is less expensive than Veeam for us, although it depends on the customer because we get a great discount."

"The solution is costly."

"Regarding pricing, I would say Avamar is slightly expensive compared to its functionalities. It's not high-priced or low-priced but somewhere in between."

"The price is the main thing I'd like to see them change. If they can come down in price, that would be a good thing. It's very cost competitive in the entry level range, because Veeam pricing is much cheaper than Avamar."

"The price of this product should be lower."

More Dell Avamar 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 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."
