Backup storage has shrunk dramatically with deduplication but still needs stronger security options
The air gap feature is something I'd really like to see in QoreStor. There's no native air gap capability right now, and for security-conscious environments, that's a gap. The configuration export is also limited in QoreStor. If you want to document your setup or migrate configuration to a new instance, it requires more manual work than it should.

Daily recovery tests have validated restore readiness and ensured consistent data protection
The best features of Unitrends include the daily reporting functionality. When backups fail, it is obvious in the logs what caused the issue. Most times it is a credential problem, which is relatively easy to resolve. Though I have experienced a few more challenging issues, nothing has affected critical backup restore functionality. Every time I have needed to restore something, it has worked successfully. The support team is readily available when I need assistance, and they help walk me through issues, solving them within a reasonable timeframe. The automated backup scheduling feature has helped our organization in managing backup timelines and consistency by handling all the work automatically. We set the schedule, breaking things into smaller chunks since our main common area for files is large. I have staggered the backups so some areas receive more attention than others, particularly for less active data. Adding, removing, excluding, and inputting elements is straightforward. The system makes it simple to schedule portions and generate reports on their functionality. The impact of Unitrends' instant recovery features on strengthening data security measures is significant. I generally use instant recovery when restoring specific files or instances where we need data that has changed. The process involves loading the backup, selecting the desired version, waiting for it to unpack, and retrieving the file. Every restore attempt has been successful. I run instant recovery daily in test mode on two virtual machines. I use it to test my domain controller and file server to ensure they communicate properly in the test environment. This ensures that in case of failure, I can activate the recovery and restore server functionality.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"I would rate QoreStor a ten out of ten for what it offers for the price."
"If storage costs are a problem, whether on-premises or cloud, QoreStor is worth a serious look."
"QoreStor has helped to reduce our backup storage requirements on-premise by at least 90%."
"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 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."
"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."
"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."
"It works as expected the vast majority of the time, which is an improvement over other products that seem to break with the slightest change in the environment."
"For what it's designed for, I will rate this product a nine and a half out of ten."
"It is an easy system to use, and the support, if needed, is always willing to help."
"Less headaches to worry about backups."
"It is an all-inclusive backup appliance that is separate from other storage needed to backup and has the ability to backup both virtual and physical nodes."
"I like the fact that you can recover the VMs inside the appliance. For example, they're basically running this appliance on a Linux-based distribution, and they're spinning off KVM virtual machines inside."
"I am impressed with the tool's reporting and UniView features."
"Being an appliance-based solution, we were able to migrate backup solutions without having to purchase a lot of hardware separately."
 

Cons

"They need to increase their maximum capacity. Other than that, they're doing a pretty good job."
"Support is one point of improvement for Quest QoreStor. Support is sometimes not adequate."
"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."
"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."
"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 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."
"Technical support has not been very helpful when there are complex issues. It is sometimes difficult to find someone who can answer questions the right way."
"In terms of improvement, the UI, especially in the recovery section, is unclear about which repository it uses."
"Scalability is where I'm running into more of an issue right now. To upgrade is pretty expensive; it's not like you can just buy a smaller appliance and put it with the one you already have, you need to buy a larger appliance and that can get fairly pricey."
"Network-based storage stability could be improved."
"There's a lot that can be made better. For example, it could be more scalable."
"Unitrends can be challenging to scale."
"Probably the biggest issue I've had is actually paying for the unit, and part of that problem is that they use a third party for the billing."
"For smaller K12 schools, I wish they offered a beefier free version with more storage and options."
 

Pricing and Cost Advice

"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."
"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."
"Unitrends is an expensive solution."
"When we renew the Unitrends maintenance contract and update it to the latest version, the cost would be $5,000 per year. There are no hidden costs. They've been transparent with the costs."
"Talk with the sales guys. They can work with you on the best package."
"Based on a scale of one to ten, with one being low and ten being high, I would rate the pricing of this solution as a three. Also, there are no additional costs involved in the standard licensing of the solution."
"Initial pricing is competitive. Renewal pricing is steep, so make sure to project costs for the lifetime of the appliance(s)."
"The cost of Unitrends definitely draws you in. The licensing is all included in the appliance, which is a great incentive."
"Pricing model constantly changes."
"With respect to cost, my advice is to get what you need."
