Active data protection has ensured high availability and supports seamless reporting workloads
In my opinion, Active Data Guard is the most valuable feature. We use the secondary side for reporting purposes, which reduces the load on the primary side. Oracle Data Guard includes functions such as automatic failover, but we use manual managed failover. After some months, we converted our primary to secondary and secondary to primary. Oracle Data Guard is effective in minimizing data loss and provides a good solution for that. The main benefits of Oracle Data Guard include minimizing data loss during a production failure. It is used for maximum availability when paired with Oracle RAC, so if any disruption occurs, we have an alternative Data Guard to convert our load to the disaster recovery site. Oracle Data Guard maintains a high level of data integrity by using archive logs. When a transaction happens, redo logs create archive logs, which are then applied on the disaster recovery side, ensuring that both databases are synchronized.

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

"Oracle Data Guard is scalable. I rate it a ten out of ten."
"The most important feature is that if I want to test the database at the disaster recovery site, I can take a snapshot, test it, and then revert it back to the original state without needing to restore the complete database from the primary data center to the disaster recovery."
"If you have a problem with your primary site and can't access your primary database, you can continue working with the database that you have as standby on the other site, by changing its role to primary."
"Data Guard also improved because customers with an active Data Guard license want to reduce the I/O in a production environment. Some application complaints to it for Oracle reporting purposes. It has a production environment that needs to be enhanced."
"It is a top-notch product, super stable, making it our go-to for internal operations."
"Provides an active data guard."
"The performance and stability are great; it doesn't crash or freeze, and I find it to be a reliable product."
"The solution is really very stable; one good thing about it, compared to other products, is that you can just run it and forget about it, and unless you come across some interruptions in the network, it works like a charm."
"Quest QoreStor definitely saved us money."
"Data deduplication and replication would be the top two features. The encryption and cloud tiering are also attractive for the future."
"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."
"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."
"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."
"This software solution can be installed on many different types of hardware, which makes it very flexible. We can run it on virtual machines or virtual servers, providing convenience for solutions of varying sizes, from small to large."
"Quest QoreStor is very stable compared to our previous solution."
"QoreStor has helped to reduce our backup storage requirements on-premise by at least 90%."
 

Cons

"For every standby server you have, you must pay a licensing fee, which is the main disadvantage."
"The initial setup is complex."
"Oracle could be improved by the ability to manage it on the cloud."
"The product could improve its pricing."
"One thing that can be improved is the GUI. It would be good to have a very nice GUI to easily configure and administer, providing different presentations to the database administrator. The feature that can be included is the integration with third-party monitoring systems, that is, monitoring systems from other vendors, not only from Oracle."
"Pricing is expensive and can use improvement."
"The implementation is complex for anyone who's jumping into it without any experience. It's all command-line driven implementations. For some, that's a turn-off."
"They may need to include the monitoring and the alerting part in Data Guard."
"The ransomware protection of QoreStor could use improvement."
"Support is one point of improvement for Quest QoreStor. Support is sometimes not adequate."
"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 air gap feature is something I'd really like to see in QoreStor."
"The management interface is in need of improvement. The graphical user interface (GUI) for the web management tools appears clunky, and not super intuitive."
"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."
"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."
"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 cost is significantly high."
"If you want to have everything automated and done smoothly, you have to add additional licenses."
"The pricing is on the higher side."
"This is the best solution if you want something similar that's less expensive than Oracle Grid."
"It's a cost-effective solution."
"The cost of the Oracle license will depend on the negotiations with Oracle."
"It is not a cheap product, but if you look at the price, features, availability, scalability, and maturity, it is a very good product."
"​Oracle Data Guard is a feature available only in Oracle Database Enterprise Edition, and is available for extra cost."
"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."
"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."
