Time Machine runs very slowly or even freezes after updating Mac to 10.7.5? Took 3 hours to backup 3.2 GB, while it only use 20 minutes in the past? Worse still, you can't perform a disk utility check and the update has killed your hard drive. Then how can you fix Time Machine broken and get back your precious data.

The most efficient method is disabling Spotlight indexing of the drive. The article below tells you how to make the Time Machine run smoothly with several methods. Also, it tells you how to recover data from Mac if Time Machine failed to backup data.

How to Make Time Machine Run Smoothly

Method 1. Disable Spotlight

The primary method is using launchctl. In the Applications/Utilities folders, open the Terminal utility and run the following command.

sudo launchctl unload -w /System/Library/LaunchDaemons/

This will require the administrative password, so please provide your password when prompted.

Another approach is to use the older indexing method. Launch the Terminal and type the following command:

sudo mdutil -a -i off

This tells the Spotlight manager to disable all indexing on all volumes which makes Time Machine slow

Method 2. Upload the Spotlight Daemon

You can manually unload the background services (daemons) that are responsible for maintaining the Spotlight index. This method is better than the first one for it will keep the current Spotlight index intact and allow you to search, but only prevent updating of the service. To disable Spotlight indexing, open the Terminal utility and run the following command:

sudo launchctl unload -w /System/Library/LaunchDaemons/

To re-enable Spotlight indexing, you can repeat the above command and change the word "unload" to "load," as in the following:

sudo launchctl load -w /System/Library/LaunchDaemons/
