Matt Reller - PeerSpot reviewer
Provides extremely fast backup, is easy to manage, and is flexible
Commvault Cloud's automated policies provide the notification we need to ensure our data is secure and managed correctly. Commvault Cloud provides excellent visibility across all of our organization's data. It is extremely important to our organization that Commvault has a unified platform that offers recovery across cloud, on-prem, and SaaS workloads. It has helped our organization improve by simplifying the way we manage our environment. We could not manage the same environment with only half of our current staff. We have yet to find anything in our environment that Commvault does not support. Commvault Cloud's Risk Analysis helps us identify, categorize, and classify sensitive data enabling us to take the appropriate actions to protect it. Commvault does a good job helping us limit our exposure and ensure compliance. Commvault has helped us reduce our data management costs significantly. Compared to Dell Avamar, the costs are vastly different. Commvault is much more cost-effective. We are licensed by capacity, so we don't have to worry about licensing different features. We have all the features that are licensed by capacity. And as far as ongoing support costs and other expenses, they are much lower than what they were with Dell Avamar. Commvault also gives us the flexibility to use any storage we want, while Avamar is tied to the Data Domain, which is not cheap to support. It has helped us reduce our backup time unless we are using Data Domain. This is because we can perform deduplication and compression on the client layer, which reduces the load on the network. We cannot do this with Data Domain. In fact, if we even attempt to perform a quick progress check before sending data to the Data Domain, the system fails completely. We learned this the hard way. We are using many more advanced features in Commvault Cloud than we ever did in Dell Avamar, simply because we had to license each feature separately in Avamar. As a result, we did not perform many backups in Avamar, such as all database backups (DB2, SAP HANA, Oracle, and SQL). These backups were performed outside of Avamar. We are now using Direct Connect agents for all of our databases. This allows us to perform incremental backups, which we could not do with the previous method. As a result, we have reduced our backup times by two-thirds, or even more in some cases. Compared to when we were backing up directly to Data Domain, Commvault is now running our backups ten times faster. This has resulted in a significant reduction in our backup times. Commvault has helped us reduce the RPO. Even in Data Domain, it has reduced our storage times by about half. It has also helped us reduce the threat detection time. We reduced the RTO significantly with Commvault. Commvault has helped us reduce downtime primarily due to the increase in the performance of resources.

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

"Real-time synchronization is a good feature."
"Commvault gives us a single platform to manage and recover our data. Since we are a research organization, backup is one of the most critical parts of our IT operations and services. Internally, we run it as a managed service, and there is a single console that makes it easy for management to see the performance."
"What I found most valuable in Commvault Complete Data Protection is its deduplication technique, mainly because the solution has the highest deduplication ratio, giving you higher storage capacity."
"Restoring is very fast. In testing, I did a restore for a single item from a mailbox. Within a minute, I had the message back in my mailbox. So, it didn't take hours or days. Obviously, there will be a limit. If we suddenly go into DR and have to restore five terabytes of emails for people, then it will take a couple of days, which would be acceptable. For general usage, where we have to do the odd restore, we have never had issues. It happens within minutes."
"The solution provides us with a single platform to move, manage, and recover our data across on-premise locations. Some of the guys have been using it to move a virtual machine from VMware to the Microsoft solution, Hyper-V. They back it up and then they restore to the different virtual machine provider, and that works great."
"When an interruption takes place due to an incident, the signaling and notification are very extensive."
"We are using a KVM system in our cloud, and this solution works very well with it."
"The solution is easy to use and the duplication is quite good."
"It's good for file services."
"I find Synology C2 Backup valuable for its speed, features, and server compatibility."
 

Cons

"The product could be more convenient in terms of working with different solutions and having more integration between the different products in the market."
"The retention log feature could be an issue for us and can be improved. The backup schedule can also be better in terms of how you set it up."
"Additional SaaS application support would be good... we have SaaS applications that may not be big enough for Commvault to support yet. Box.com is one we've asked about for years, and it's just not on the radar, as far as I know."
"The Java interface is not great. The Command Center interface is far better and it looks nicer, but it doesn't have all the powerful features available in the CommServe/Java console. The place to improve the product is on the management interface level."
"I just wanted to compare the features, which are there in EMC NetWorker, which are not available in Commvault. We have things using Networker."
"Compared to Rubrik, MongoDB Data Protector, and NetBackup, Commvault is better. The licensing team was quite tricky recently because they stopped the unlimited files for that license. Commvault made a bank of 500GB only, a node-based license can take it, which is disappointing. Reporting needs to be more granular. Also, there should be a showback of data being backed up, and the backup cost to share the cost internally with the department."
"When we send a query to Commvault, they take a long time to answer our questions."
"Could be easier to implement."
"The main drawbacks of Synology C2 Backup are slower processes in certain regions and less frequent updates."
"Improving the pricing would be great."
 

Pricing and Cost Advice

"In my experience, compared to solutions like Veritas and Veeam, while they do have their technical pluses and minuses, Commvault can save you on average forty percent initially, and then twenty to twenty-five percent annually."
"Some of our customers say that Commvault is a very expensive solution, but Commvault has many features that the competitors don't have. It is not a good choice for a small or medium business, but it is a good choice for enterprise businesses."
"We like that there is no extra cost for SharePoint, Teams, or OneDrive. It is all mimicking Microsoft's model. Every user has one terabyte of space. When users start using OneDrive, everybody has one terabyte that will be backed up included in the price."
"If budget allows using the per socket license and not the agent based with per GB counter for Dedup is the way to go."
"Its cost is reasonable, but anybody else can do better benchmarking."
"Originally, it was really attractive when we were deployed on-prem. They have since built and moved it to the cloud, which I am a big fan of. I have all my security tools in the cloud, but it came with a significant increase in pricing. We ended up negotiating a better price because we have been a long-term customer, and I have also spoken on their behalf quite a few times, but if I have to buy it at its current rate, I am not sure if I would be a customer. It is expensive."
"On a scale of one to ten, where ten is the highest price, I rate the pricing an eight."
"It would not be affordable for small to medium size organizations."
