Cloud Continuity for PCs: Rapid Rollback - Getting Started



This article describes the Datto Cloud Continuity for PCs Rapid Rollback process for disaster recovery.

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


  • Datto Utilities
  • Datto Cloud Continuity for PCs
  • Datto Cloud Continuity Agent 


Cloud Continuity 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 a 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 Cloud Continuity for PCs 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 Cloud Continuity solution.


Is Rapid Rollback the best option?

If you need help to determine which restore method will work best for your situation, see our Datto disaster recovery guide.

What happens during a rollback?

During the restore process, the Cloud Continuity 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 to the protected disk which has changed since the time of the selected backup. Data which has not changed since the capture of the selected snapshot is not overwritten.


  • The target machine must:
    • Be able to boot from USB.
    • Use 64-bit hardware.
    • Have ethernet access.
    • At least be able to boot into a Windows OS of the same type.
  • If you are restoring to different hardware than the original, the new hardware must use the same partition scheme and be running the same operating system as the original system.
  • The restored storage size of the disk to be restored must not exceed 1 TB.
    • You can restore to a larger disk, but the agent will fail to back up until you expand the filesystem and then shrink it to less than 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


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


  • This process will only restore the OS volume.
  • Before performing a restore, disable the Windows 10 Fast Startup feature (external link) 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 restore process will revert the last backup.
  • 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. Download the latest version of the Cloud Continuity Restore image from or the Download Utility link shown in Figure 1.
