Storm season is back, bringing with it the potential for significant weather events. If you have clients in areas prone to infrastructure disruption, visit the Disaster Recovery Resources guide for preparedness information. Datto recommends performing proactive disaster recovery testing to mitigate potential downtime.

Rapid Rollback: Performing the Restore

Follow

Topic

This article describes the procedure for performing a Rapid Rollback in a disaster recovery scenario.

Review the Rapid Rollback: Getting Started article for important pre-deployment considerations and instructions before attempting this process.

Environment

  • Datto SIRIS
  • Datto ALTO
  • Datto Utilities
  • Rapid Rollback

Prerequisites

This article assumes that you have already booted the target machine into the Datto Utilities environment and have selected the Rapid Rollback option. If you have not already done this, see the Booting a Target Machine with Datto Utilities article.

Procedure

1. After the Rapid Rollback environment loads, you will see a list of the Datto appliances detected on your local network. Select the device that holds the production machine's backups.

2. Enter the username and password of a local user authorized to access the device, as shown in Figure 1. Then, click Next.

3. Select the Protected Machine to restore from the list of available backed up machines. You must select the backup data for the target machine you are restoring; you cannot restore the target machine with data from a different system. Click Next.

4. Select the date that you want to restore the target machine to, and then click Next. Datto only recommends restoring recovery points that have passed local verification testing without issue. Learn more about Local Verification here.

If you receive the error message "The volumes to be restored do not match the volumes on the protected system" during this step, either the volumes on the production machine have changed since the selected backup was taken, or you have selected a protected machine that does not match the hardware you are attempting to restore to.

When the restore mounts, you will see a corresponding iSCSI share appear in the Restore section of the host Datto appliance's UI. Do not remove this restore - if you do, you will need to restart the Rapid Rollback process from the beginning.

5. Select the volumes to be restored. Click Next.

6. Review and confirm your restore configuration. Then, click ROLLBACK

When prompted, enter ROLLBACK in the confirmation box, and click Confirm.

This step will irretrievably destroy any data on the production machine that did not exist prior to the selected rollback date. Be absolutely certain that you wish to proceed before doing so.

7. The rollback will run, restoring the target machine. As each volume is completed, its completion status will be reported, as shown in Figure 8. The restoration may take some time to complete; during this process, do not remove the Datto Utilities USB drive or reboot the production machine.

8. Once the rollback completes, you will see the Finish and Reboot prompt. Remove the Datto Utilities USB drive from the target machine, and click Finish and Reboot. The target hardware will reboot in its restored state.

The next backup of your production system following a Rapid Rollback will be a Differential Merge. This allows the Datto appliance's backup engine to reconcile the differences between the most recent backup taken prior to the restore and the new state of the production machine, preserving the integrity of your backup chain.
