### Before You Start

Instant VM Restore can quickly restart a VM directly from a compressed and deduplicated backup file to minimize downtime of production VMs. Compared with full VM restore which takes longer time but has full I/O performance, instant VM restore can restart the VM within seconds but has limited I/O performance.

#### Note:

1. To finalize the whole instant VM restore process, you will need to migrate the instant restored VM back to the production site. You can choose to migrate VM or clone the VM to the hypervisor where you want to run the VM. It’s advised that the VM be shut down in case of data inconsistency during cloning. Migration of VMs requires eligible vCenter / Storage vMotion license, please refer to Migrate VM for further information.
2. Since all the changes made during instant VM restore will be automatically stored on NAS, please make sure that there is enough space on you NAS.

### Launch the Instant VM Restore Wizard

### Restore Wizard: Select VMs and Restore Point

### Restore Wizard: Select Restore Mode

Select a mode for your restoration.

- Restore to the original location: Initiate restore of selected VM to the original location, and with the original name and settings. This option minimizes the chance of user input error and will unregister and replace the original VM in the production site.
- Restore to a new location, or with different settings: customize a destination and settings for the restored VM.

### Restore wizard: Configure Restore Settings

For users who choose Restore to the original location, you will pass directly to the summary step of the wizard.

For users who choose Restore to a new location, or with different settings, please specify the name and select folder, hypervisor, resource pool, network to run the restored VM. Changes made during instant VM restore will be stored on Synology NAS, and you may select the datastore when executing VM migration.

### Restore Wizard: Apply and Restore

In the summary step, please check the information of restored VMs and click Apply to restore VMs and users will be automatically directed to Restore Status to monitor the restoration progress. To finalize the whole instant VM restore, please click migrate VM.

Enable power on VM automatically if you want to run the restored VM immediately. For testing purpose, it’s suggested not to select this option and manually disconnect the initial VM from the production network to avoid conflicts.
