Offers near-real-time replication for data consistency and continuously introducing new features through upgrades

There are various advantages. First of all, easy to deploy. The only difficult part is the cost factor, licensing. In other ways, the implementation is very, very important. Like, 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. Once you configure it, it goes through the rollback, and then Data Guard introduces this snapshot thing. So once the restoration happens, we can go back to the original thing, and we make that a standard. It's a pretty decent and key function for Oracle. So, enterprise organizations go for Oracle only for features like these.

Jeff Manuszak

CTO at EDSI

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

"The most valuable feature is the application or promotional code used in the production protocol to transfer data to the secondary database, situated on the DR site."

"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."

"One of the most valuable features is real-time replication. The version we're using is reliable and easy to deploy."

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

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

"We use Data Guard for online replication from data center, to data center for high availability. This is the most important feature."

"The solution has been stable so far."

"The solution is quite stable. We haven't experienced any bugs, glitches, or crashes. We find it to be quite reliable."

More Oracle Data Guard pros

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

"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."

"Quest QoreStor definitely saved us money."

"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."

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

"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."

"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."

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

More QoreStor pros

Cons

"We would like to be able to see the date time stamp when you execute DGMGRL commands."

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

"The deployment cost is expensive."

"The product could improve its pricing."

"Sometimes, the technical support team takes time to respond."

"The usage of block storage devices in the cloud or migration of a type of storage from one site to another site can be improved. Currently, we have to use multi-node to single node because of the lack of storage support on the Azure side. It did not really work. Our DBA had to spend a lot of time tweaking the Data Guard tools, or the underlying Oracle VMs, to make sure that Data Guard would run on top of different types of storage. So, if it can support transporting or getting from one type of storage to another type of storage in a different site or a different technology, it would be very helpful."

"The IP implementation and maintenance are a little bit hard to manage across Oracle solutions, including Oracle Data Guard."

"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."

More Oracle Data Guard cons

"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."

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

"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 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."

"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. 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."

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

More QoreStor cons

Pricing and Cost Advice

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

"The pricing is on the higher side."

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

"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 licensing cost is significantly high."

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

"The cost is expensive."

"It's a cost-effective solution."

More Oracle Data Guard pricing and cost advice

"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."

"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."
