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.

Cost-efficient, highly scalable, and installable on different types of hardware

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. We are pretty lenient as we do a lot of IT support ourselves. We are not very hard on support organizations, but when a customer has a support issue, it would be easier if the support processes were a little bit more automated. It would be beneficial to have an easier way to upload diagnostic dump files. They can make it easy for the customer to collect the diagnostic data. 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. This is especially critical because it stores customers' backups, and a failure can have significant business impacts. If a customer does not have the backups and has a disaster, they can be out of business, so monitoring is key.

Quotes from Members

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

Pros

"One of the most valuable features is real-time replication."

"The solution has been stable so far."

"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."

"With Data Guard, Oracle guarantees zero data loss, providing peace of mind for organizations relying on their data for critical operations."

"It is a top-notch product, super stable, making it our go-to for internal operations."

"Backup and application continuity are most valuable."

"We have dealt with Oracle's customer service for eight years, and their service is astonishingly good."

"This is one of the most stable products to support critical DR sites."

More Oracle Data Guard pros

"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."

"Since we started to resell QoreStor, we have been using it internally; it's better than other backup solutions we have used or evaluated."

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

"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."

"QoreStor has helped us to reduce our backup storage requirements on-premises, and we've been using the same devices for quite a while, so it lets us keep using them as opposed to having to rip out all that hardware and create a new on-prem solution."

"Quest QoreStor is very stable compared to our previous solution."

"I would rate QoreStor a ten out of ten for what it offers for the price."

"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."

More QoreStor pros

Cons

"They may need to include the monitoring and the alerting part in Data Guard."

"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."

"For every standby server you have, you must pay a licensing fee, which is the main disadvantage."

"The deployment cost is expensive."

"I think it would be great to have a graphical interface assistant (like DBCA, ASMCA, NETCA, etc.) for initial configuration, monitoring, configuring Oracle Data Guard Broker and all the Data Guard Broker commands, without needing Oracle Enterprise Manager Cloud Control installed."

"We sometimes had scalability issues with read only."

"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."

"It is a very useful administrative IT tool. It saves on costs."

More Oracle Data Guard cons

"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."

"Support is one point of improvement for Quest QoreStor. Support is sometimes not adequate."

"The ransomware protection of QoreStor could use improvement."

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

"The setup of the software is definitely not the easiest thing in the world."

"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 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."

More QoreStor cons

Pricing and Cost Advice

"The cost is expensive."

"It is not a cheap product, but if you look at the price, features, availability, scalability, and maturity, it is a very good product."

"If you want to have everything automated and done smoothly, you have to add additional licenses."

"The licensing cost is significantly high."

"The pricing is on the higher side."

"This is the best solution if you want something similar that's less expensive than Oracle Grid."

"Oracle Data Guard is a feature available only in Oracle Database Enterprise Edition, and is available for extra cost."

"The cost of the Oracle license will depend on the negotiations with Oracle."

More Oracle Data Guard pricing and cost advice

"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."

"Its pricing model is very attractive. You have one price, and you get everything from QoreStor."

"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."
