No Sir. Not an option at all. It does not "reduce" reliability, it _ignores_ data changes. This is like replacing a failed disk in a RAID1, but then not rebuilding it. If the corresponding other disk fails, data is lost completely. DO NOT use skip-sync. Never. This is a "wizards only" thing, and probably should not even be documented :) Lars Ellenberg
