This article describes the Restore tab of the Datto appliance GUI. For a complete discussion of Disaster Recovery options, see the article Datto Disaster Recovery Guide.
- Datto SIRIS
- Datto ALTO
- Datto NAS
From the Restore page of your Datto device, you can perform disaster recovery operations. To do so:
1. Access the GUI of your SIRIS, ALTO, or NAS. Then, click the Restore tab, as shown in Figure 1.
You will see the Restore from a Backup screen shown in Figure 2. Depending on the model of your appliances, some features may or may not be available. See the Recovery Types section of this article for more information.
This screen represents the first three steps in the recovery process:
- Choose a protected system or share.
- Choose a recovery type.
- Choose a recovery point.
This section provides definitions of all possible recovery features accessible from a Datto appliance's Restore page. To determine which features are available for your specific model of Datto appliance, see the Additional Resources section of this article.

Consider a file restore if you do not need to virtualize or perform a Bare Metal Restore of a machine. This option allows you to mount the selected recovery point as a LAN-accessible Windows Samba share and as a web-accessible share. File permissions are not preserved. All users with access to the share will have access to its entire file structure. If you only need to retrieve data, this option is quicker and easier than the other options.
See the Performing a Local File Restore article for more information.
Use a volume restore if you do not need to virtualize or perform a Bare Metal Restore of a machine, but you would like to restore files with their NTFS permissions intact. When you select this option, the contents of the chosen recovery point will be shared over your network as an iSCSI target. All files and folders in the recovery point will restore with the ACL attributes they had at the time the snapshot was taken.
You can read more about this feature in the Performing a Volume Restore article.
The Local Virtualization option allows you to create a virtualization of a selected recovery point and host it locally on your Datto appliance. Use a Local Virtualization when you need the continuous operation of a protected system, and the Datto appliance is available and has the computing resources available to virtualize the system.
This option is available for Windows and Linux protected machines. To learn more, see the article Start A Local Virtualization.
Virtualize in the Cloud / Hybrid Virtualization
This virtualization option allows you to host a virtualization in the Datto Cloud and bridge it to your local network through your Datto appliance. Use this option when you need the continuous operation of a protected system, your restore point is already in the Cloud, you have adequate bandwidth, and you want to use the computing resources of the Datto Cloud, rather than your Datto appliance.
This option is available for Windows and Linux protected machines. For more information, see the article Hybrid Virtualization On A Datto Appliance.
Virtualize via Hypervisor
This option allows you to offload a local virtualization to your vSphere or Hyper-V hypervisor to take advantage of its superior system resources. Use this option when you need the continuous operation of a protected system, you have a hypervisor connection available, and you want to use the computing power of your server to virtualize the protected system while using the Datto appliance as a datastore.Note that you may experience increased disk I/O overhead on the hypervisor when virtualizing multiple machines.
This option is available for Windows and Linux protected machines. To get started with ESX virtualization, see the article ESXi Virtualization Configuration.
This option uploads a restore point to a connected ESX host via VMware Converter. Use this option if you want to use the ESX host for computing power and as a datastore. Depending on the size of your datastore, this may take a while to transfer, but once it is transferred, there is no disk I/O burden on the Datto appliance, nor need for adequate bandwidth between the Datto appliance and the ESX host. The datastore is thick provisioned on the ESX host, which increases the speed of the virtualization.
This option is available for Windows and Linux protected machines. You can read more about the EXI Upload feature in the Performing and Troubleshooting an ESXi Upload article.
This option does not appear in the Datto appliance GUI, but it is available for all SIRIS and ALTO appliances via the Datto Utilities environment. Rapid Rollback allows you to restore only the files which changed on a production machine since the last backup. Use this option to undo widespread file changes, such as those caused by a ransomware infection, or to restore deleted data to its original state and location on a protected system.
See Rapid Rollback: Getting Started to learn more.
Bare Metal Restore
The Bare Metal Restore option allows you to use the Datto Utilities environment to completely reimage a protected system from a selected snapshot. Use this option if the production machine's operating system cannot be repaired, and you need to restore it to a previously backed-up state.
For further information about the Bare Metal Restore feature, review the USB Bare Metal Restore (BMR): Getting Started article.
Diskless Restore is an alternate method of performing a virtualization of a protected system. Instead of virtualizing a recovery point directly from the Datto appliance, you can offload the virtualization to any target hardware capable of booting from a USB stick. The imaged USB stick uses iPXE on the network card of the local machine to boot, and then virtualizes the recovery point from the Datto appliance.
Consider diskless restore as an alternative to local virtualization if:
- The amount of resources needed by the virtualization would be prohibitive to allocate on the Datto appliance.
- You need a higher level of performance than what the virtualization can deliver on the Datto appliance.
- You have spare hardware that is available for you to temporarily image as a production machine.
- Virtualization via hypervisor is not an option.
See the Diskless Restore article in the Datto Knowledge Base to learn more.
This option allows you to export a selected recovery point to vSphere Hypervisor (via VMDK or VMDK-linked) or Microsoft Hyper-V (via VHD or VHDX). You can export to an attached USB drive or a network share (CIFS/Samba or NFS).
Consider an image export if you need to completely re-create a virtual machine from a previous backup, or if a protected machine's physical hardware has failed, and you will be returning it to production as a virtual host.
This option is available for Windows and Linux protected machines. To get started with image exports, see the Restore: Export Image article.
Use this option if you want to restore an iSCSI file share as an iSCSI target. Consider an iSCSI restore if you want to attach a file restore to a production machine as a logical volume with all file permissions intact.
For more information about iSCSI restores, see the article Creating And Accessing An iSCSI File Restore.
The iSCSI Rollback feature allows you to roll back an iSCSI share hosted on your Datto appliance to a previous recovery point. All data added after the chosen recovery point will be destroyed. You should consider an iSCSI rollback if irreparable damage has been done to the NAS share, such as widespread file deletions or ransomware infection.
For an in-depth look at this feature, see the Performing An ISCSI Rollback article.
File Restore (External NAS)
The File Restore option for external NAS shares allows you to mount a selected recovery point as a LAN-accessible Windows Samba share and as a web-accessible share. File permissions are not preserved. All users with access to the share will have access to its entire file structure. Use this feature if you want to restore the contents of a protected externally-hosted NAS share without their original ACL attributes.
To learn more about this feature, see the Restoring an External NAS Share article.
File Restore with NTFS Permissions (External NAS)
If you chose to back up a selected NAS share with NTFS permissions intact, this option will be available. The contents of the selected recovery point will be shared over your network as an iSCSI target. All files and folders in the recovery point will restore with the ACL attributes they had at the time the snapshot was taken. Use this recovery option if you want to restore an externally-hosted NAS share with its file permissions intact.
