When the Screenshot Verification process runs for an agent, it never progresses past the Getting Devices Ready screen, resulting in a failed screenshot.
- Datto ALTO
- Datto SIRIS
This error occurs when the Screenshot Verification process takes a screenshot before the login screen displays. Virtualizations can take longer to boot on a Datto appliance than they do in the production environment. This is often because the virtualization has to run Sysprep on its Windows installation the first time it boots. Sysprep generalizes the Windows configuration for deployment onto new hardware.
Extended boot time can result in a screenshot capturing "Getting devices ready" instead of the Windows login screen. Datto appliances will mark this as a failed screenshot because the Windows environment has not fully booted.
Using a Local or Hybrid Virtualization
The Screenshot Verification process virtualizes your protected system to ensure that the selected snapshot will boot in a disaster scenario. A failed screenshot can be caused by the boot process failing to complete or timing out. You can investigate the cause of the boot failure further by creating a local or hybrid virtualization and observing the results.
If the virtualization eventually boots, note the boot time and select it in the Additional Wait Time setting. If the virtualization fails to boot or reboots during the Getting Devices Ready screen, contact Datto Technical Support.
Additional Wait Time for Screenshot Verification
Increase the screenshot's Additional Wait Time:
- In the Datto device GUI, click the Protect tab.
- Click Configure Agent Settings for that machine experiencing the error.
- Scroll down to the Screenshot Verification section, then increase the Additional wait time setting.
Adjusting services startup type
Certain services may cause a delay in a machine startup. This issue is most common with Microsoft Exchange services.
To solve this issue, delay the start of one or more services by doing the following:
- On the protected machine, go to
- Right-click the Exchange Transport service and select Properties. Change the startup type from Automatic to Automatic (Delayed Start).
- Right-click the Information Store service and select Properties. Change the startup type from Automatic to Automatic (Delayed Start).
- Take a backup of the protected system.
- Force a Screenshot Verification to see if the problem persists.
If you don't know which service is causing the problem, you can start a Local or Hybrid Virtualization, open Event Viewer, and review event logs for any errors that Event Viewer logged during startup. If you identify a service in any error messages, change its startup type to Automatic (Delayed Start).
