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…

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

"Avamar's source side deduplication is very strong, it can easily back up remote sites' data, and not much bandwidth is required on the Avamar side."

"The initial setup is easy."

"All the features in the system are highly valuable."

"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."

"The solution integrates well with Unix, Windows, Hyper-V and VM."

"We have seen huge data reduction and data deduplication and compression, which is very cost-effective and cost-reducing for the company."

"I always recommend Dell Avamar to our enterprise customers because the product is costly, and enterprise customers can afford it."

"We are talking about a complete end-to-end solution which comes with its own hardware storage to back up the data on tape-less."

More Dell Avamar pros

"Quest QoreStor definitely saved us money."

"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."

"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."

"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."

"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."

"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."

"Data deduplication and replication would be the top two features. The encryption and cloud tiering are also attractive for the future."

"Quest QoreStor is very stable compared to our previous solution."

More Quest QoreStor pros

Cons

"We don't trust the product 100 percent. Kaspersky has many features Dell Avamar doesn't support, such as granular backup and history."

"The stability could improve, a lot of scheduled backups failed at one time."

"The reporting should be improved, as we currently have to use another tool for that purpose."

"A huge storage space needs to be bought with Dell Avamar, even when it's unnecessary for an organization"

"A benefit would be support for either Azure Cool Storage or AWS Glacier."

"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."

"When you get down to doing certain things, such as somebody wants a particular file restored, the process by which you do that is stupid. You kind of have to know exactly where to look for in order to find it. Even on older backup products that I've used, I didn't have that kind of problem. If we were looking for a file with a particular kind of a name, the solution would find that file anywhere irrespective of where it resides within the backup system. So, we didn't have to know the name of the specific server, the specific timeframe, almost all the characters of the file name, and all kinds of data in order to find a file. In Avamar, we got to know these details. We've gone around and around with them on that, and their attitude seems to be that it is working just fine. There is nothing for them to improve. The organizational system of other products that I'm working with, such as Zerto and Cohesity, seems to be centered around the tasks that you would most commonly do and want to do, as opposed to we've laid it out in a really neat technical hierarchy."

"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."

More Dell Avamar cons

"Support is one point of improvement for Quest QoreStor. Support is sometimes not adequate."

"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."

"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."

"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."

"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 management interface is in need of improvement. The graphical user interface (GUI) for the web management tools appears clunky, and not super intuitive."

"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

"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."

"I rate the tool's price as a three out of ten if one means expensive and ten means it is a cheaply priced tool."

"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 was very expensive before, but after integrating it with Dell EMC Avamar Data Protection suite licensing, we are getting better discounts."

"I rate the pricing a seven out of ten because it is expensive."

"The solution is not expensive for the value one gets."

"The price is fair."

"The cost is high."

More Dell Avamar pricing and cost advice

"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."

"Its pricing model is very attractive. You have one price, and you get everything from QoreStor."
