Have supported critical environments despite room for improvement in legacy backup options

It is very efficient in cyber resilience. Deduplication, automation, and everything is very efficient. It is multi-cloud enabled and has broad protections. The software delivers flexible and efficient backup and recovery options through its cyber resiliency features. Dell PowerProtect Manager provides insights in managing backup processes. Its encryption mechanisms are very efficient, helping to secure sensitive data. Its integration with Dell EMC Data Domain is very good. It is easy to integrate with Data Domain. Multi-cloud options are enabled, and backup in cloud options exist in Dell Avamar.

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

"The solution is easy to use and has high performance."

"It is very easy when you want to restore back to the original state."

"The product is very powerful and offers very good performance."

"The most valuable feature for me is the backup functionality."

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

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

"In general, when you look at the spec sheet for Dell EMC Avamar, it's a very good product."

"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

"Not having to be onsite to swap tapes on a daily, weekly, or monthly basis, alone, has really paid for its usage through the savings in time."

"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."

"Since we started to resell QoreStor, we have been using it internally; it's better than other backup solutions we have used or evaluated."

"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."

"Overall, it simplifies the management of backup and gives me a more secure feeling that my data is going to be available if I need to retrieve it."

"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."

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

"QoreStor has helped us to reduce our backup storage requirements on-premises, and we've been using the same devices for quite a while, so it lets us keep using them as opposed to having to rip out all that hardware and create a new on-prem solution."

More QoreStor pros

Cons

"We have had issues with performing backups in our hybrid environment."

"The user interface still needs to have some level of improvement. It could be more user-friendly and intuitive."

"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."

"Avamar is dependent on the hardware. It can't be implemented with ordinary storage."

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

"It's very slow to backup and store information. It has two consoles and an application which are more difficult to use than a solution like Veeam."

"The initial setup is a bit complex and could be simpler."

"The client caches and deduplication system have a few problems."

More Dell Avamar cons

"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 setup of the software is definitely not the easiest thing in the world."

"They need to increase their maximum capacity."

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

"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."

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

More QoreStor cons

Pricing and Cost Advice

"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 costly."

"On a scale of one to five, I would rate the pricing policy of Dell Avamar as five. The solution has a very good price, and a lot of improvements were done to it."

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

"The price is the main thing I'd like to see them change. If they can come down in price, that would be a good thing. It's very cost competitive in the entry level range, because Veeam pricing is much cheaper than Avamar."

"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."

"Regarding pricing, I would say Avamar is slightly expensive compared to its functionalities. It's not high-priced or low-priced but somewhere in between."

"The price is fair."

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."
