Works excellently for on-prem backup but not the best for Azure backups
Avamar is not the best tool when it comes to taking Azure backups. Like Commvault, if Avamar can support VM-level backups for the cloud, that would make it a bit better. There is another Dell EMC tool called NetWorker, which is a bit centralized tool. If you deploy a storage node locally, you can use the same UI tool for central management, but in the case of Avamar, it needs to be deployed individually on a site, irrespective of whether it's small or big. So, if I have 10 sites, I have to manage 10 Avamar. That's a bit of a headache. The Dell EMC solution professionals who connect with the clients should suggest NetWorker to clients with multiple sites rather than Avamar. That's because NetWorker gives more centralized control, but they keep recommending Avamar, which isn't the best practice. There are no free or cheaper training plans. Unless your company is a partner with Dell, you don't get the student guide training, etc. Their administrator guide does not have all the information required for a new person. It doesn't cover the basics. The student guide is good, but it's not free. If you are a partner, only then it's free. Otherwise, there is a cost of $2,000 to $3,000. For people who are new to Avamar, there should be some resources to enable them to study on their own at least 50% of the basics. If I want to study Commvault, I get so many documents and resources to study, but in the case of Dell EMC products, there aren't any free resources. Only if you're a partner, the resources are available for you to learn. The user manuals and administrator guides are just for deployment. They aren't good for learning the basics for a fresher.

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 product has a proven track record of good backups without much of a failure ratio. It also has a good backup in terms of the compression ratio."
"We have a lot of backups, and this tool helps us with the RMAN Backup."
"They are extremely reliable and scalable — they provide the best de-duplication on the market."
"We've found the product to be stable."
"It's simple to configure."
"What I found valuable in Dell Avamar is the deduplication feature. I also like that the solution can be integrated with Data Domain."
"I have found the product to be scalable."
"The most valuable feature is the integration with Data Domain and your VM stacks."
"I would rate QoreStor a ten out of ten for what it offers for the price."
"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."
"Quest QoreStor is very stable compared to our previous solution."
"Quest QoreStor definitely saved us money."
"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."
"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."
"Data deduplication and replication would be the top two features. The encryption and cloud tiering are also attractive for the future."
 

Cons

"The licensing model is not very flexible. Every time we upgrade our storage size, we need to upgrade the Avamar license."
"I would like to see better integration with third-party applications and platforms."
"There are instances where backups fail on certain applications, which is an area that could be improved."
"There also needs to be single sign-on support."
"It would be helpful if there was cloud support."
"Dell hasn't done a good job at handling these upgrades, or the way EMC used to handle them."
"The only concern is the cost."
"The product could be improved by simplifying the components available."
"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."
"The management interface is in need of improvement. The graphical user interface (GUI) for the web management tools appears clunky, and not super intuitive."
"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."
"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 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."
"Support is one point of improvement for Quest QoreStor. Support is sometimes not adequate."
 

Pricing and Cost Advice

"The solution is not expensive for the value one gets."
"Licensing fees are paid annually."
"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 cost of the solution is very expensive."
"This is a fairly expensive solution. It cost approximately 21,000 each year."
"There are licensing costs for Dell EMC Avamar and it is paid annually."
"Dell Avamar is expensive."
"It's an expensive tool"
"The cost is per terabyte, and overall, the cost was reasonable when compared to some competitors."
"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 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."
