  • Datto SIRIS
  • Datto ALTO
  • Datto NAS


A scheduled backup has not taken place within 24 hours on a device.

  • You have decommissioned the agent or system.
  • There is an active RoundTrip, or Technical Support is performing ongoing troubleshooting on the device.


The Datto device will only display this error when no other errors are preventing a backup.
  • Verify that you are not running a Roundtrip and that no one has paused backups for any reason.
  • If you have decommissioned the agent or system, remove all scheduled backup entries.
  • If this is the first time you're seeing this error, you can attempt to trigger a backup manually on the device.
  • Repair agent communications
  • If you are still unable to trigger a backup manually, reboot the Datto device and attempt to start another backup.
  • If this error persists after trying these steps, open a ticket with Datto Technical support to investigate the cause of this error.
