Is it normal for TimeMachine to be able to manually backup when it is OFF?
Have had numerous problems with iMac since I bought it. Latest is failure of external Time Machine hard drive. Turned Time Machine off in system preferences and found it could still "Back Up Now" even if Time Machine was off. This seems like a problem to me. Is it? I would like to know.
iMac (21.5-inch, Late 2012), iOS 7.0.3
