Direct to Cloud (DTC) Rapid Rollback: Getting Started



This article describes the Direct to Cloud (DTC) Rapid Rollback process for disaster recovery.

For the SIRIS and ALTO-based Rapid Rollback procedure, see Rapid Rollback: Getting Started.


  • Datto Utilities
  • DTC Rapid Rollback
  • Datto Direct to Cloud (DTC) Agent


DTC Rapid Rollback is a cloud-based disaster recovery process that allows you to boot a target machine into a recovery environment, and restore it to previously-backed-up state from a recovery point hosted in the Datto Cloud. Recovery from the cloud requires the protected machine to be backed up via the Direct to Cloud agent.

During this process, only the data which changed is written back to the live environment, preserving bandwidth, reducing recovery time, and eliminating the need to perform a complete reformat of the target system.

Its function is similar to the SIRIS and ALTO-based Rapid Rollback utility, but its use is exclusive to agents protected by the Datto Direct to Cloud solution.


Which recovery method is right for you?

Disaster recovery needs can take many forms. The following table will help you make an informed decision about which recovery utility is best-suited to your scenario.

DTC Rapid Rollback Direct to Cloud Virtualization Direct to Cloud File Restore
Ransomware recovery Testing bootability of recovery points Restoring a single file or small number of files
Restoring uninstalled software Temporarily restoring a protected machine in the Datto Cloud  
Restoring damaged system files     
Undoing widespread file changes    

What happens during a rollback?

During the restore process, the DTC Rapid Rollback engine performs the following actions:

  1. It establishes a connection to the Datto Partner Portal via Datto's Rest API.
  2. It identifies changed data by performing a block-level comparison of the current state of the protected machine to the state it was in at the time of the selected snapshot.
  3. It transfers the changed data to the protected machine via an encrypted MercuryFTP connection.
  4. It incrementally writes the data which has changed since the selected backup was taken to the protected disk. Data which has not changed since the selected snapshot was taken is not overwritten.


  • The target machine must be able to boot from USB.
  • The target machine must use 64-bit hardware.
  • The storage size of the disk to be restored must not exceed 1 TB.
  • The environment of the target machine must meet Datto's networking requirements. See the SIRIS, ALTO and DNAS Networking & Bandwidth Requirements article for more information.

You should have the following items available when starting this process:

  • USB stick that is at least 8 GB


  • DTC Rapid Rollback is only available for 64-bit Windows 7 and Windows 10 operating systems.
  • DTC Rapid Rollback cannot restore systems encrypted with BitLocker. For more information, see our BitLocker Considerations article.


  • DTC Rapid Rollback can only be used to restore to the same hardware that the selected snapshot originated from. Attempting to restore a snapshot to different hardware will cause the process to fail, and may leave the target machine in an unbootable state.
  • This process will only restore the OS volume.
  • Before performing a restore, disable the Windows 10 Fast Startup feature and shut the target machine down gracefully. Attempting a restore on a protected machine that has not been gracefully shut down can result in a failed restore attempt and potential loss of data.
  • Any new data created on the protected machine since the last backup will be reverted by the restore process.
  • A restore operation cannot be stopped or undone once started. Interrupting the process could leave the target hardware in a non-bootable state.
  • Software and firmware-based RAID configurations are unsupported.


1. Image a USB stick with the latest version of the DTC Restore image. For more information about this process, see Imaging a USB Drive with Datto Utilities.

2. Proceed to the Booting a Target Machine with Datto Utilities article to continue.
