Ayodeji  Oyewole - PeerSpot reviewer
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 product is good for backups."
"The function I find most valuable in Dell Avamar is its ability to take differential backups for users. This feature is very effective for both backup and restore operations. We've had multiple cases where we needed to restore files directly from Avamar, and it worked perfectly. The Delta feature, which captures changes in user files, is particularly useful."
"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."
"Every product is good and bad, but its claim to fame is that it is scalable. We're doing more than 3,000 VMs. Every single night a complete image backup to disks and replication are easily done in under four hours."
"Duplication and the speed of backup are great."
"The solution is very stable."
"The deduplication feature is the best aspect of the solution."
"It is very easy when you want to restore back to the original state."
"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."
"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."
"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."
"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."
"It integrates with various backup software solutions, which makes it compatible with existing backup workflows and processes."
"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

"The solution is not very strong on the Cloud. They should work out how they can use this as a backup as a service."
"It's not the best solution for big databases."
"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."
"Compared with Cohesity or Rubrik, which have some continuous data protection for backup and replication, this solution tends to lack in this area."
"The client caches and deduplication system have a few problems."
"EMC has discontinued their Avamar hardware version. They only advertise the Avamar virtual edition."
"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."
"The ransomware protection of QoreStor could use improvement."
"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 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."
"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."
"Support is one point of improvement for Quest QoreStor. Support is sometimes not adequate."
"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."
 

Pricing and Cost Advice

"When it comes to competition the price is not what is important, it's not the problem."
"Dell Avamar is expensive."
"Dell Avamar is free when we deploy the data protection. When we order data protection, this software is included in the hardware."
"It might not be beneficial to smaller businesses due to its high cost."
"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."
"Dell Avamar is a moderately priced solution."
"It is expensive. Its cost is the main thing."
"It was approximately $70-80,000 when it was under support, but right now EMC has not been supporting this product for two years."
"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 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."
"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."
