olivierlambert I did the update and I'm getting the same error.

Herer are the log 2024-04-11T11_47_11.366Z - backup NG.txt

Sense my mirror incremental backup take a while to do the copy because of internet speed. I had to do update to another commit this morning. I will retest de backup job but still getting the error on the latest commit from last week.

mguimond Could be corruption in the disk. What commit are you on for XO? Is your host fully patched?
