I want to warn about a problem I once had with Time Machine. The HDD in my Mac failed, taking 10 years of family photos with it. No problem, I told my wife, I have backed up on an external disk using Time Machine . I installed a new HDD and clean OS, and started the overnight process of restoring about 2 TB from Time Machine. It didn't work. Tried three times. Each morning I'd find the process hung. From the logs I could see it was hanging at the same place each time. Finally I stayed up and watched the process, saw it hang, figured out which file it was hanging on, deleted that file from the backup, and tried again. Finally success. I was stressed out during those the days, knowing that my photos were now living on a single drive with no further backup. So now I use multiple backups and I don't rely on Time Machine alone.
