Cloud Continuity for PCs: "OS Volume Backup Failed For Reasons: Is Greater Than 1TiB"



When attempting to back up a system protected by the Datto Cloud Continuity for PCs Agent, you receive the error message, "OS volume backup failed for reasons: is greater than 1TiB."


  • Datto Cloud Continuity for PCs


The OS volume of the protected system is in excess of 1 TB in size.


1. If the protected system's OS disk has been resized, the Cloud Continuity agent may no longer be able to see it. Ensure that the protected system's OS volume does not exceed 1 TB in size.

2. Attempt a backup by selecting the Take backup now option from the Cloud Continuity agent's tray icon.
