[QUOTE=dnanian;13927]Hi, Tom. It reindexes because the index is not preserved across copies. If you don't want it to index your backup, you can add the backup drive into the Spotlight Preference Pane's "Privacy" tab.
Hi David,
I seem to have a different behaviour pattern with Smart Updates. Spotlight is functional on the Clone/Back-Up(after the Smart Update) but goes through a full index procedure on the main internal drive after each Smart Update.
I am not aware of doing anything different ie I copy all files from the main/internal HD drive to the external drive using Smart Update and have never used the option of the Spotlight privacy tab.
