Has enabled seamless disaster recovery with virtual rollovers and rapid failovers between systems

Improving Precisely Assure MIMIX is going to be a really hard one; over the years, the tech support started off kind of rough but gradually got better and better as I used it often, being on a first-name basis with many of the customer service reps because of having to call with issues that they were always able to resolve fairly quickly. I would have liked to see more reporting, maybe automation of reports, but as far as integration with other systems, I always used Precisely Assure MIMIX on an AS/400, iSeries, IBM iSeries machine, and I cannot speak to using it on any other device.

Cost savings and efficient data management improve operations but support quality varies

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. I always had to get it escalated or ask for someone specifically because those other people would just read knowledge-based articles that I had already done myself. Quest QoreStor does not work with any backup software, server, or storage hardware. It has the hardware compatibility list, and you need a specific number of IOPS, so it needs to run on decent hardware at least to have enough input-output operations. Otherwise, the setup result will be canceled. I'm not too sure if there are still physical appliances, but when I first started, we had some customers with a physical Quest QoreStor appliance, and it would only run on certain hardware. It doesn't work with every backup program. For example, Veritas Backup Exec is incompatible, but Veeam is compatible, and V Ranger is compatible as well. I didn't even know that Quest QoreStor has any static AI and behavioral AI technologies.

Quotes from Members

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

Pros

"The product's initial setup phase was straightforward and simple."

"Database replication is most valuable. It is multi-platform, so it can replicate from a variety of different database types to a variety of different database types."

"Precisely Assure MIMIX has positively affected our organization by reducing downtime because it takes 30 minutes from swapping from one box to another; production is back up and running within 30 minutes, and a lot of times, I could get it down to 20 minutes."

"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."

"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."

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

"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."

"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."

"Quest QoreStor definitely saved us money."

More QoreStor pros

Cons

"It does data manipulation language (DML) replication, but it does not do data definition language (DDL) replication. In my opinion, it is a disadvantage. It would be nicer if it was able to do both DML and DDL. I'm not 100% certain of this, but it seems Oracle Golden Gate does both DML and DDL. MIMIX only does DML, and it would be very nice if they included DDL replication. This is one feature that would be very helpful to have."

"The pricing was a little steep; I believe it could have been lower, but for what I received as far as the service, the price is pretty close."

"The high cost of the product is an area of concern where improvements are required."

"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 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 ransomware protection of QoreStor could use improvement."

"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."

"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."

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

"Overall, I am happy with this solution, but a way to export configuration settings would be beneficial. After everything is set up and configured, there should be a way to export the configuration. In case something happens to the QoreStor server, and we need to reinstall and configure everything, being able to import the configuration would be helpful. This feature does not currently exist."

More QoreStor cons

Pricing and Cost Advice

"The licensing provides the access to support. I do know that there's an annual charge for being able to call into their support line and get a technical team from Precisely to assist with any issues we may have. I don't think there are any additional costs other than what we incur internally in terms of the infrastructure that we need to run and operate the product."

"The cost of the product is too high."

"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."

"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."
