Jeff Manuszak

CTO at EDSI

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

"Quick incremental backups and product replication are the two highlights of the product. Once you capture a full backup, incrementals are pretty quick. It is fairly efficient from that perspective."

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

"The stability is okay."

"It works quickly and is very stable."

"It is one of the best solutions for backing up Oracle and other servers."

"They are extremely reliable and scalable — they provide the best de-duplication on the market."

"The most valuable feature for me in Dell Avamar is the automation, which is good for completion."

"Source based deduplication is the most attractive feature as it drastically reduces the backup window."

More Dell Avamar pros

"It integrates with various backup software solutions, which makes it compatible with existing backup workflows and processes."

"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."

"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 definitely saved us money."

"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."

"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."

"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."

More QoreStor pros

Cons

"If you don't have DPA, the reporting features are not as user-friendly, so reporting is something that they can improve on."

"Backup image browse times should be faster."

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

"Some customers need to back up to tape, but Avamar lacks support, so it costs a lot."

"The tool's interface is very much in a spreadsheet format...reporting is an area with shortcomings requiring improvement."

"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."

"It would be helpful if the product offered more integration potential."

"The configuration and expansion aspects of the solution need improvement. They're complicated and don't really integrate well."

More Dell Avamar cons

"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."

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

"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."

"Overall, I am happy with this solution, but a way to export configuration settings would be beneficial."

"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."

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

"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."

"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."

More QoreStor cons

Pricing and Cost Advice

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

"It is easy to use."

"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."

"Licensing fees are paid annually."

"It's a very high-end solution and comparable to Rubrik and Cohesity."

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

"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."

"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."

More Dell Avamar pricing and cost advice

"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."

"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."
