When I use FreeFileSync with ACL to make a backup from a Windows drive to another Windows drive there is no problem. But when I try to make a backup with ACL from a Windows drive to a NAS, that failed systematicaly with the message "Code Erreur 1: Incorrect function. [SetFileSecurity]" . If I disable the ACL's there is no problem to make the backup. So it is possible to desactivate automaticaly ACL's for some backup?
