Featured Reviews

Ayodeji  Oyewole - PeerSpot reviewer
Reliable with good backups but has occasional failures
I use Dell Avamar primarily for backup and recovery The most valuable feature for me is the backup functionality. It gives large enterprises the comfort of knowing their workloads are being backed up. There are instances where backups fail on certain applications, which is an area that could be…
Jeff Manuszak - PeerSpot reviewer
Cost-efficient, highly scalable, and installable on different types of hardware
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. We are pretty lenient as we do a lot of IT support ourselves. We are not very hard on support organizations, but when a customer has a support issue, it would be easier if the support processes were a little bit more automated. It would be beneficial to have an easier way to upload diagnostic dump files. They can make it easy for the customer to collect the diagnostic data. 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. This is especially critical because it stores customers' backups, and a failure can have significant business impacts. If a customer does not have the backups and has a disaster, they can be out of business, so monitoring is key.

Quotes from Members

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

Pros

"The solution scales well."
"The product is very powerful and offers very good performance."
"It's simple to configure."
"It is very easy when you want to restore back to the original state."
"Source based deduplication is the most attractive feature as it drastically reduces the backup window."
"Easy to configure and highly reliable for backup."
"The entire system operates seamlessly, with minimal hands-on involvement, allowing us to focus on monitoring rather than constant adjustments or deployments, as seen in larger, more dynamic environments."
"The stability of Dell EMC Avamar is very good."
"I would rate QoreStor a ten out of ten for what it offers for the price."
"It integrates with various backup software solutions, which makes it compatible with existing backup workflows and processes."
"Quest QoreStor is very stable compared to our previous solution."
"Data deduplication and replication would be the top two features. The encryption and cloud tiering are also attractive for the future."
"Quest QoreStor definitely saved us money."
"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."
"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."
 

Cons

"The product could offer more integration capabilities."
"The solution used to freeze sometimes while taking a snapshot backup."
"Dell EMC Avamar is a very complex product. It took a lot of time for the IT admins to get trained on how to use it. It is not very user-friendly, and we won't be using Avamar anymore. It needs a lot of improvement in terms of how the backups have been configured, and the reporting is too complex."
"The solution, in the future, should offer support for mobile."
"Avamar cannot back up Nutanix as a virtual solution."
"I would like to see better integration with third-party applications and platforms."
"Setting up Avamar wasn't so easy, and we had a partner doing the installation for us. Though it was hard at first, it's getting better. The main difficulty was finding plugins for Oracle Database. It took some time to open a ticket with Dell, but everything was fine after that."
"We have had a lot of problems with the Dell EMC Avamar solution. The snapshots are not being erased after backup."
"Support is one point of improvement for Quest QoreStor. Support is sometimes not adequate."
"The management interface is in need of improvement. The graphical user interface (GUI) for the web management tools appears clunky, and not super intuitive."
"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 ransomware protection of QoreStor could use improvement."
"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."
"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."
"They need to increase their maximum capacity. Other than that, they're doing a pretty good job."
 

Pricing and Cost Advice

"The cost is high."
"Dell's pricing structure is not overly expensive."
"It is very expensive. It's a trust based licensing. So that's an ethical challenge."
"Dell Avamar is free when we deploy the data protection. When we order data protection, this software is included in the hardware."
"The solution is not expensive for the value one gets."
"This is a fairly expensive solution. It cost approximately 21,000 each year."
"Avamar's pricing is quite competitive compared to other vendors."
"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 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."
"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."
