Devin Mehta - PeerSpot reviewer
IT Manager Infrastructure & Security at VISBY MEDICAL, INC.
Secure backups have simplified compliance and now provide immutable protection for cloud workloads
The best features that Clumio offers are the ability to know when a backup has completed, to know how to restore both files at the file level and also restore EBS backups, point-in-time restores, as well as snapshots. Clumio has positively impacted our organization by providing us with the peace of mind of knowing that all of our EC2 instances are securely backed up. This peace of mind has translated into measurable outcomes as we adhere to NIST 800 compliance, and with that, we need immutable backups and the ability to have backups that do not exist within our existing tenants. Clumio fixes that problem for us.
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.
