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

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

"Another valuable feature is the possibility of backing up the database from the standby database instead of the primary database, to avoid backup process overhead in the primary system."

"Snapshot and Data Guard Manager are awesome features."

"The performance and stability are great; it doesn't crash or freeze, and I find it to be a reliable product."

"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."

"The most valuable feature is the flashback standby, which allows us to test without scrapping the database."

"I would recommend that every implementation that goes to the production environment must be done together with Oracle Data Guard."

"I think for our company, the way we use it, we are very happy with it and the end customer is very happy with it."

More Oracle Data Guard pros

"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."

"QoreStor has helped to reduce our backup storage requirements on-premise by at least 90%."

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

"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."

"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."

"If storage costs are a problem, whether on-premises or cloud, QoreStor is worth a serious look."

"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."

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

More QoreStor pros

Cons

"If one is most stable, I'd rate it a two out of five. We were facing some issues."

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

"Pricing is expensive and can use improvement."

"The deployment cost is expensive."

"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."

"Oracle could be improved by the ability to manage it on the cloud. This on-premises version is secure and reliable, but I'm sure that they will soon provide a cloud solution that will be even better. In one to two years, we will probably move to the cloud—we have already moved to the cloud with Microsoft Exchange, but our databases are still on-premises. I would prefer managing a cloud version of Oracle."

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

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

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 ransomware protection of QoreStor could use improvement."

"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."

"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."

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

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

"The air gap feature is something I'd really like to see in QoreStor."

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

More QoreStor cons

Pricing and Cost Advice

"It's a cost-effective solution."

"The pricing is on the higher side."

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

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

"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 cost is expensive."

More Oracle Data Guard pricing and cost advice

"The cost is per terabyte, and overall, the cost was reasonable when compared to some competitors."

"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."

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