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.

Expert Backup at a tech services company with 201-500 employees

A virtual deduplication backup appliance that protects physical and virtual data across remote sites, the datacenter and cloud deployments

Given its ease of use and management, I believe there are no specific caveats that users need to be aware of during the setup of DXRIS for backups. The process was straightforward, and I did not encounter any challenges or issues. As for a rating on a scale of one to ten, with one being the worst and ten being the best, I would rate the Quantum DXI Series a nine. My deduction is primarily influenced by personal preferences, particularly regarding the user interface and it is a highly commendable system, I would rate it a solid nine out of ten.

Quotes from Members

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

Pros

"We have found the replication feature the most useful. We use this feature the most. The ability to recover a database with less effort and the use of Oracle Data Guard Broker to administer the complete environment are also very useful features."

"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."

"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."

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

"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."

"Snapshot and Data Guard Manager are awesome features."

More Oracle Data Guard pros

"While the challenges posed by the difficulties were significant, they prompted the replacement of problematic components, resulting in the resolution of issues. Importantly, there were no substantial ongoing concerns. Regarding the overall performance, it has been consistently excellent."

"I am impressed with the tool's technical alliance with Veeam and Veritas."

Cons

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

"The deployment cost is expensive."

"The predominant issue lies in the communication link between the secondary and primary databases."

"The product could improve its pricing."

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

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

"The only difficult part is the cost factor, licensing. Another area of improvement is support."

"There is an issue with their application on ODG. There were a lot of edits in the logs. Sometimes, we only get a little cue from the Data Guard Broker logs if there's an issue."

More Oracle Data Guard cons

"Perhaps the most notable area for enhancement lies in the web interface for management. The current limitations in LDAP editing capabilities are not addressed in the UI, and I haven't observed any recent updates. It's possible that the new version of the DXI service incorporates improvements in the GUI, but I cannot confirm. While there is room for improvement in the current GUI, it remains a relatively minor issue. Overall, the system is comprehensive, covering aspects such as reports on latency and networking, leaving little room for additional enhancements in those areas."

"The product needs to improve performance while scaling out. It also needs to improve stability."

Pricing and Cost Advice

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

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

"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 is expensive."

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

"It's a cost-effective solution."

"The pricing is on the higher side."

More Oracle Data Guard pricing and cost advice

"I do not oversee this aspect, as pricing is contingent on factors such as volume, technical specifications, and the desired features. Consequently, I lack information on the pricing details and structure."
