Apple's Mac OS X v10.6 was released last Friday, and for most of us the
transition from Leopard to Snow Leopard went by without incident.
However, we've spent part of last weekend scouring Apple's discussion
boards and support site for solutions to problems people have been
reporting with the upgrade.
I sometimes get Time Machine errors that say something like “Backup
failed” or “Unable to complete backup” or “An error occurred while
copying files to the backup volume.” How am I supposed to interpret
what these error messages mean?
The only sure thing about hard drives is that they fail. Backing up the data on your Mac turns a hard drive failure into a non-event, instead of a Mac disaster. If you run Leopard, Time Machine makes backups easy.
