Hi, I set up a scheduled backup job that included the system image and several folders with important data. It ran successfully the first time and several times afterwards on schedule. However, since yesterday, I noticed that the scheduled backup operation fails to complete, and it also fails when I run it manually.I couldn't get any useful information out of the event viewer. The relevant section is below. This is on RC. General: The backup operation that started at '2009-07-01T09:28:11.722896300Z' has failed with following error code '2155348299'. Please review the event details for a solution, and then rerun the backup operation once the issue is resolved.
