Re: Backing up special files in Windows

Regarding your second question. Don't use the dontchmod and perms
preferences at all. These should be used only when you run into actual
problems that can't be solved otherwise or when you have some very specific
needs. The read-only attribute will be synced (unless you set dontchmod to
true or perms to 0) but I don't think others like hidden or archive will be
synced. You can also sync the actual permissions by using the "acl"
preference.
