Ensures high availability, disaster recovery, and data protection for Oracle databases through features like real-time data synchronization, automatic failover and zero data loss

Oracle Data Guard stands out by providing heavy-duty features that enable connecting multiple standby databases to a single production database. Oracle supports up to eight standby databases, offering a level of redundancy and scalability that other platforms cannot match. Implementing Oracle Data Guard ensures the protection and integrity of your data, even in the event of a disaster. With Data Guard, Oracle guarantees zero data loss, providing peace of mind for organizations relying on their data for critical operations. Data Guard offers multiple protection modes, each serving different needs. One such mode is active-active, where both the production and standby databases are actively accessible. In the event of a failure, seamless switchover occurs without disrupting client sessions, as they remain unaware of the transition between databases.

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

"Oracle Data Guard has a nice feature called the DataGuard snapshot to open the solution in the read-write mode and make some changes to the database."

"We have not encountered any major challenges with replication. We were able to achieve near-real-time replication. Also, with the switchover failover, we were not getting any technical issues. It's a pretty stable product."

"Oracle Data Guard is scalable. I rate it a ten out of ten."

"Oracle Data Guard is a free solution. When you apply for Enterprise Manager, it comes for free with the solution."

"The solution has been stable so far."

"You can see how the logs are applied, check the apply time, and how far behind the standby is at any given time."

"Technical support is very good. If at any time we write a ticket, we get the appropriate answer on time."

"The most valuable aspect for me is undoubtedly the failover capability and the assurance of data safety provided by Oracle Data Guard."

More Oracle Data Guard pros

"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."

"Quest QoreStor definitely saved us money."

"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."

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

"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."

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

"It integrates with various backup software solutions, which makes it compatible with existing backup workflows and processes."

More QoreStor pros

Cons

"The initial setup is complex."

"The product could improve its pricing."

"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."

"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."

"The database administration needs improvement. With Oracle, we have a lot of features for administrating data, but it might be too many. It needs to be simplified. It should be automated. Looking at Enterprise Manager, there are too many KPIs in place."

"A significant improvement for Oracle Data Guard would be enabling the disaster recovery site to handle read and write operations, not just data storage."

"It is a rather complex solution, so it could be more user-friendly."

"The deployment cost is expensive."

More Oracle Data Guard cons

"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."

"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 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."

"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."

"They need to increase their maximum capacity. Other than that, they're doing a pretty good job."

"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."

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

More QoreStor cons

Pricing and Cost Advice

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

"The pricing is on the higher side."

"The cost is expensive."

"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."

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

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

"The licensing cost is significantly high."

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."

"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 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."
