Lacks multi-platform support and physical infrastructure but excels in storage optimization
We use it for VM backup and Office 365 backup I find the solution to be user-friendly and easy to manage and deploy. It provides storage for Office 365, which is beneficial, and the deduplication technology is excellent, especially in optimizing storage capacity compared to others. In terms of…
Zuhair Hasan - PeerSpot reviewer
Manager, Information Technology Security at Nesma
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 interface is user-friendly and even if our tech isn't onsite, we can work with the owners to confirm that the data will be restored with no issues."
"Reverse Delta is Altaro proprietary backup deduplication technology. With Reverse Delta, the latest version of a file is always made available in its entirety, not as a delta file."
"Valuable features for us include quick recovery, compression, and deduplication, and the mix of these features leads to a reduced backup footprint while having guaranteed fast recovery in case of DR."
"I have no reservations recommending Altaro for the Hyper-V based small to medium sized business."
"This product is not expensive, does the job what I bought it for, and is not time consuming."
"VM backup and the item level recovery are the most valuable features."
"No other product offers these features for this price."
"Altaro is always our go-to VM backup software."
"It's good for file services."
"I find Synology C2 Backup valuable for its speed, features, and server compatibility."
 

Cons

"Backup speed and comparisons between versions used to be slow on big VMs but that was improved greatly later on."
"The cloud backup and VMware support (now available in the latest releases), could do with some improvement."
"Being able to backup the actual host machine would be an improvement for us."
"Sometime there are stability issues with older kit, for example, it can take a long time to compress the primary backup."
"It would be good to if they would expand the functionality to be able to backup normal servers without Hyper-V."
"Basically, how it works is that you have a single local drive, and then you have a cloud backup. It'd be nice if you could rotate the single local backup drive. As of now, you can't."
"We use Linux guests on Hyper-V clusters and we really need the file level restore on these VMs (ext3 and 4 file systems) functionality."
"The replication time between virtual machines is slow."
"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

"The price is great for the utility you get and the licensing has never caused any issues with my company."
"There is a free version for two VMs. I would advise to study the deployment environment well, prior to committing to order a license per host."
"Its yearly maintenance fee is fairly high for me to renew for upgrades and support."
"VMware is a little pricey, but it is a good solution and priced similar to other products."
"The pricing is okay,"
"There is a free version for Hosts with 2 VMs."
"No other product offers these features for this price. The ROI is great."
"Altaro VM Backup is affordably priced. It is a best value for its price and has almost every feature that an expensive, popular product offers."
