Ransomware recovery has become validated and protects critical workloads across multiple accounts
The account onboarding process deploys around 20 IAM roles per account, which is heavy. Consolidating those or offering a slimmer permission set for read-only backup (versus full restore) would help with security review friction. Cross-account restore into a target account still requires manual steps for KMS. If Clumio could handle re-encrypting with the target account's CMK during restore rather than requiring Multi-Region Key pre-staging, that would save significant preparation time. Also, the restore API could surface better progress telemetry since right now, large RDS restores are a bit of a black box until they complete or fail. Finally, DocumentDB and MongoDB Atlas backup support would round out our stack nicely.

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.
