Time Machine
Time machine randomly deleted ALL backups two days ago, not just the oldest to make room. Completey "started over" and backed up over 700 gig of information. Now my latest backup is 2 days ago rather than months ago. What happened? My concern is that happening and the Mac crashing and I have no backup. Is this a glitch in the time machine?
