How to temporarily turn OFF Spotlight Indexing?

It was suggested to me that it is best to turn off spotlight indexing for the duration of an initial clone backup of your system drive. How can this be done? Thanks.

The advice you have been given is incorrect. There is no need whatsoever to turn Spotlight off even temporarily. Just prior to the cloning you should check that indexing of your boot volume is not occurring - simply because the competition for CPU will slow the cloning down. Just click on the Spotlight symbol at the right hand end of your menubar to see that you only have the text entry box.


Also, there is usually no need to have a clone indexed, and so you should put the target volume into the Privacy tab of System Preference / Spotlight -- that will ensure that your target does not start to be indexed during the cloning and that the target volume does not become indexed later. Should you ever need to work on the clone and want it to be indexed, just remove that volume from 'Privacy'.

Thanks everyone. Andreas, your suggestion sounds much easier writing code in terminal, but I have a concern. When I go into the Privacy tab of System Prefs / Spotlight, the title of the window states, +"Prevent Spotlight from searching these locations."+

Am I to assume this also means that the HDD will not be indexed by Spotlight? Since I made this setting, I have not noticed any indexing occurring on by backup HDD, but just want to make sure. Thanks again.

Your assumption is correct. A volume in ‘Privacy’ won’t be searchable because it will have no index. I would agree with you that that wording is not as well chosen as it might have been! 🙂


Don’t forget that if you ever erase that volume the OS will remove it from Privacy and you will need to replace it. Otherwise it will remain there.
