Find out what your peers are saying about Dell Technologies, Hewlett Packard Enterprise, NetApp and others in Deduplication Software."The solution is very stable."
"All the features in the system are highly valuable."
"The data reduction feature and the ease of enabling a server in a DR location are the most valuable."
"We love the instant recovery functionality. It's very useful."
"They are extremely reliable and scalable — they provide the best de-duplication on the market."
"The most valuable features are image backups and file backups."
"The product is very powerful and offers very good performance."
"The performance of Dell EMC Avamar is good."
"It integrates with various backup software solutions, which makes it compatible with existing backup workflows and processes."
"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."
"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."
"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. 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."
"There are limitations when trying to use this solution with Hyper-V."
"We have had a lot of problems with the Dell EMC Avamar solution. The snapshots are not being erased after backup."
"What would make Dell Avamar better is if it can do faster backups because right now, PowerProtect Data Manager is better in this area with its new UI and a new way to implement backups. Customers nowadays also expect more up-to-date solutions, and this is another area for improvement in Dell Avamar. It's not as up-to-date, so I'm counting on PowerProtect Data Manager, but customers who have Dell Avamar don't want to switch because you don't have as many backup problems in Dell Avamar compared to other solutions. What I'd like to see in the next release of Dell Avamar is an updated UI and a different way to manage backups because currently, backup management is a bit heavy for customers using Dell Avamar."
"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."
"If you don't have DPA, the reporting features are not as user-friendly, so reporting is something that they can improve on."
"We don't trust the product 100 percent. Kaspersky has many features Dell Avamar doesn't support, such as granular backup and history."
"Desktop-laptop backups and backup over the WAN needs lot of improvisation. For DTLT there must be a provision to push agents from the management console."
"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."
"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 ransomware protection of QoreStor could use improvement."
"The management interface is in need of improvement. The graphical user interface (GUI) for the web management tools appears clunky, and not super intuitive."
"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 need to increase their maximum capacity. Other than that, they're doing a pretty good job."
