Enhanced filtering for advocate emails

Quorum provides an elevated ability to filter on everything from people's location to age to their voting history. This is an extreme feature that will help our advocacy department a lot. It encompasses the ability to formulate emails and calls to action across regions. Their platform is more advanced than our previous one. It provides a smooth training experience and easy terminology for those in the advocacy world.

Provides fast access to files and offers a reliable backup solution without compatibility issues

Versioning control helps speed up data recovery by providing easy access to previous versions of files. This is particularly useful when moving backups to off-site storage and deploying them quickly during installations. My experience with Synology Backup's security features includes partitioning for production environments, regular scans for new threats, and support for multifactor authentication. Password security is also emphasized, meeting basic security requirements. Before choosing Synology, consider its sensitivity in your network infrastructure, especially for critical backup and storage tasks. Prioritize security, including testing and recovery procedures, and evaluate the device's performance to ensure it meets your needs effectively. Overall, I would rate Synology C2 Backup as an eight 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

"The most useful feature is the one-click recovery."

"One of the biggest features is that, even on the absolutely run-of-the-mill box, if I lose any one of my servers I can automatically bring it up virtually on the physical onQ Quorum device."

"One of the most valuable features was the usability, since many of the features were very straightforward. The backup and restoration process was also very fast. Although we weren't able to fully test the scenarios, one of the features was that we could have it restored on a remote site. However, since we were on-prem, we weren't able to test the remote site restoration."

"Being able to spin up a machine in a sandbox is amazing because it allows us to test things that we otherwise would not be able to do."

"When it comes to recovering what you need from a backup, it's really easy. You just drill through the directory, find the file and the date that you want, and click to recover. You then pick the directory you want to save it in. Usually, it takes a minute or two and it's done. It's quick and easy."

"It does automated tests to the systems to make sure that you could spin them up if you needed to. And if something doesn't come back up in those tests, we get a notification saying the system didn't come back up."

"The most valuable feature of Quorum OnQ is quick recovery."

"It is a very scalable solution."

More Quorum OnQ pros

"It's good for file services."

"I find Synology C2 Backup valuable for its speed, features, and server compatibility."

Cons

"They have radio buttons that allow multiselection, which is not intuitive. Also, the URL for our environments is the same, making it confusing for management when handling different departments with different needs."

"I paid for subscription of Firewall. I paid for subscription of endpoint protection. Thet should introduce single subscription for all services."

"The user interface needs to be improved."

"One thing that could be done to improve it would be a single pane of glass for doing disaster recovery testing, where I could have remote consoles in one place... I still have to go to each location in a browser and then bring up the console. I'd like to see them integrate that into a single pane of glass so I don't have to go to each server."

"The price of Quorum OnQ could be improved. We were exploring the product in terms of having a partnership with the distributor so that we could operate as a service, but for our own use, within the company, we couldn't justify the price unless the servers would become an option later on. The upfront cost of purchasing a license for the hardware is quite steep."

"They need integration with other platforms."

"Better integration with cloud-based solutions like Azure and Office 365 is needed."

"We found that some of the live SQL databases we were backing up would be inconsistent when we would restore them."

More Quorum OnQ cons

"Improving the pricing would be great."

"The main drawbacks of Synology C2 Backup are slower processes in certain regions and less frequent updates."

Pricing and Cost Advice

"We have never questioned whether it is worth it because it so obviously is a great value."

"I am not sure how much it costs, but I know it's expensive."

"The total for our current solution's licensing is about $14,000 for 12 servers for three years."

"The cost is higher than other software and services, but it is an absolute must-have."

"The pricing is about $1,400 a month. It's a little bit on the higher side. But it's one of those situations where time is valuable for me. So if it costs a little bit more money for me to have a solution that just works and requires less of my day-to-day management, I'm willing to pay a little bit more."

"The solution’s pricing is economical."

"The upfront cost of purchasing a license for the hardware is quite steep."

"The initial expenditure for us was a little under $40,000 for the recent renewal. For the first three years after that, other than electricity, there's no cost. After that, their support contract has to be renewed annually. We spent close to $6,000, between the two offices, for support."
