To provide full I/O performance, you must migrate these "temporary spares" to the production site. This means that Veeam Backup & Replication creates fully functioning “temporary spares” with limited I/O performance. When you perform Instant Recovery, Veeam Backup & Replication mounts workload images to a host directly from backups stored on backup repositories. The workloads are recovered in a matter of minutes. Instant Recovery helps improve recovery time objectives (RTO), minimize disruption and downtime of production workloads. With Instant Recovery to VMware vSphere, you can immediately recover different workloads (VMs, EC2 instances, physical servers and so on) as VMware vSphere VMs to your production environment by running them directly from compressed and deduplicated backup files.
