Hello @florent , the results below between 8:04:10 and 8:04:36 seem to align with one of the three failed VM backups. NB: The error did not return when I did another Delta backup (everything backed up successfully). I am now doing a Force Full Backup on all VMs just to be safe. As of now I am still running 1a7b5 and have not yet updated to 7994f.
