UPDATE: Apple released a OS X Lion 10.7.5 Supplemental Update which fix the Time Machine slowness bug
After the installation of the latest 10.7.5 Lion update the Time Machine service had started to take ages even to make an easy backup. And when I’m talking about ages, I’m not joking:
With the new Mac OS X Lion out since a week I decided to upgrade my Mac Book Pro but at that time I didn’t know it will be a little long journey.
Time Machine is a powerful solution to backup, restore or move your Mac OS X installation to another machine or just after a full reinstall of the operating system. The restore system is smart enough to put all your applications, profile files, and all other stuff which belong to you.
For some files and folders (for example MacPorts installation and XCode folder) the restore process, to be safe, renames that files or folder appending a
(from old mac) string, wasting hard drive space.
