> In other words, always blame the software. > I get it, but the convenience of things like ZFS and Time Machine have a cost. It takes time to implement such things and they take resources. And even then a failure is possible. You need to weigh the development cost of a feature against the cost to the user of not having it times the number of users. It is usually cheaper to make the software do the tricky stuff than to make your users do it.
