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 performance of Dell EMC Avamar is good."
"The most valuable feature is the virtual backup."
"Graphically, it's very user interactive. It's got a very nice interface."
"The solution integrates well with Unix, Windows, Hyper-V and VM."
"For the on-prem backup, it has all the necessary features that we require. They keep coming up with new scripts and new updates."
"Easy to configure and highly reliable for backup."
"It is very easy when you want to restore back to the original state."
"We have seen huge data reduction and data deduplication and compression, which is very cost-effective and cost-reducing for the company."
"Data deduplication and replication would be the top two features. The encryption and cloud tiering are also attractive for the future."
"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."
"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."
"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."
"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."
"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

"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."
"Technical support should be more knowledgeable."
"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."
"Avamar needs a greater emphasis on storage targets. If it's going to keep pace with the times, it needs more ability to leverage cloud storage."
"Dell hasn't done a good job at handling these upgrades, or the way EMC used to handle them."
"The product could offer more integration capabilities."
"Interfaces need to be improved."
"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."
"They need to increase their maximum capacity. Other than that, they're doing a pretty good job."
"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."
"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 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 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 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."
"Support is one point of improvement for Quest QoreStor. Support is sometimes not adequate."
"The ransomware protection of QoreStor could use improvement."
 

Pricing and Cost Advice

"It is very expensive. It's a trust based licensing. So that's an ethical challenge."
"Dell EMC needs to lower Avamar's price and add more features to stay competitive."
"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 price is fair."
"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 solution is expensive."
"I'm not sure, but perhaps the pricing could be done better at the moment."
"When it comes to competition the price is not what is important, it's not the problem."
"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."
"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."
