Notes from the field, following a disk failure…
The short answer: Time Machine works flawlessly.
The longer story:
I don’t have a Time Capsule here - I just stuck a 1TB drive into an external enclosure, partitioned and formatted it with Disk Utility, then pointed Time Machine at it. Less than half the price of a Time Capsule, and I have no need for the wireless function.
For the past few months, Time Machine has been unobtrusively taking notes and backing up my files.
This past Tuesday, the unthinkable happened. Instead of booting, my Mac’s hard drive just goes tick-tick-tick-tick-tick. Dead drive. :eek:
A little research later, and I have almost excessively detailed instructions from www.ifixit.com on how to get into the iMac and change the drive. About two hours later, the Mac has a new 1 TB drive. (My good luck to have this happen at this time of year when the shops are open later than usual!)
I plug the external drive in, fire up the Mac with an OS X disc in the CD drive, and step one is to partition and format the new drive. If you can remember it, use the same name that it had earlier - probably “Macintosh HD.” Then, just pick the option to restore with Time Machine. Select the most recent backup and it sets off - after a couple of minutes, it said the process will take about 5 hours.
Five hours later, Mac is back! Desktop icons are right where they were, applications are installed, and not so much as a single email was lost. It’s like nothing ever happened.
If you have a Mac and are not using Time Machine, you need to start using it!
