Instant Recovery to VMware vSphere

In this article

    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. Instant Recovery helps improve recovery time objectives (RTO), minimize disruption and downtime of production workloads. The workloads are recovered in a matter of minutes.

    When you perform Instant Recovery, Veeam Backup & Replication mounts workload images to a host directly from backups stored on backup repositories. This means that Veeam Backup & Replication creates fully functioning “temporary spares” with limited I/O performance. To provide full I/O performance, you must migrate these "temporary spares" to the production site. For more information, see Migration of Recovered VMs to Production Site.

    Besides disaster recovery matters, Instant Recovery can also be used for testing purposes. Instead of extracting workload images to production storage to perform regular disaster recovery (DR) testing, you can run a workload directly from a backup file, boot it and make sure the guest OS and applications are functioning properly. For more information, see Finalizing Instant Recovery to VMware vSphere.

    Instant Recovery supports bulk processing so you can immediately recover multiple workloads at once. If you perform Instant Recovery for several workloads, Veeam Backup & Replication uses the resource scheduling mechanism to allocate and use optimal resources required for Instant Recovery. For details, see Resource Scheduling.

    Supported Backup Types

    You can recover workloads from the following types of backups:

    You can also recover VMware vSphere VM data directly from storage snapshots.

    How Instant Recovery Works

    When Instant Recovery is performed, Veeam Backup & Replication uses the Veeam vPower technology to mount a workload image to an ESXi host directly from a compressed and deduplicated backup file. Since there is no need to extract the workload from the backup file and copy it to production storage, you can perform recovery from any restore point in a matter of minutes.

    The image of the workload remains in read-only state to avoid unexpected modifications. By default, all changes to virtual disks that take place while a recovered VM is running are logged to auxiliary redo log files residing on the NFS server (backup server or backup repository). These changes are discarded as soon as the recovered VM is removed, or merged if you migrate the VM to the production site.

    To improve I/O performance for a recovered VM, you can redirect VM changes to a specific datastore that is closer to the host where the VM resides. In this case, Veeam Backup & Replication will trigger a snapshot and will put it to the Veeam IR directory on the selected datastore, together with metadata files holding changes to the VM image.

    Migration of Recovered VMs to Production Site

    To migrate the recovered VMs to the production storage, you can use one of the following relocation methods:

    For more information on the relocation methods, see Quick Migration. For more information on how to launch the migration for workloads recovered with Instant Recovery, see Finalizing Instant Recovery to VMware vSphere.
