CloudStack Native Backup & Recovery is built into the CloudStack core platform. From version 4.20 onward, it includes the KVM with NAS B&R Plugin, which allows administrators to perform native, agentless full and incremental backups of KVM instances using a shared NAS (e.g., NFS) backend. Backups can be scheduled via backup offerings (similar to service offerings), applied at deployment time, and restored on-demand through the CloudStack UI or API. The framework also supports other third-party backup providers via plugin architecture, but the KVM + NAS integration enables fully standalone backup operations for users relying solely on open-source components.
