Featured Reviews

Rob - PeerSpot reviewer
Cyber Security Admin/Governance, Risk, Compliance at Grede Wisconsin Subsidiaries, LLC
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.

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.

Quotes from Members

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

Pros

"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."
"I see that the seamless synchronization feature is helpful for your organization or your customers' organization."
"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, and it is a relatively stable database replication product."
"The product's initial setup phase was straightforward and simple."
"If storage costs are a problem, whether on-premises or cloud, QoreStor is worth a serious look."
"Since we started to resell QoreStor, we have been using it internally; it's better than other backup solutions we have used or evaluated."
"Quest QoreStor definitely saved us money."
"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."
"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."
"I would rate QoreStor a ten out of ten for what it offers for the price."
"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."
 

Cons

"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."
"There is certainly a strong lobby in the company that feels that by having so many copies of the same set of data throughout the organization, we are going in the wrong direction."
"The high cost of the product is an area of concern where improvements are required."
"One thing I see as a drawback in Precisely Assure MIMIX is that deployment is quite complex and it takes time."
"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."
"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."
"Overall, I am happy with this solution, but a way to export configuration settings would be beneficial."
"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 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."
"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 air gap feature is something I'd really like to see in QoreStor."
"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."
 

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."
"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."
"The cost is per terabyte, and overall, the cost was reasonable when compared to some competitors."
"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."
