Question: I need some backup software for just backing up files of a particular type or a smart folder. In this case I need to backup all my video. Is there a free backup software available that will accomplish this for me?

Answer: 
```
To display the status of indexing
# mdutil -s /
To clear the metadata store
Turn indexing off for /
# mdutil -i off /
Clear the metadata store for /
# mdutil -E /
Turn indexing back on for /
# mdutil -i on /

```
My suggestion is to rebuild the Spotlight index. The easiest way to do that is a freeware app called Onyx. It also clears caches and performs a number of mac maintenance items. Search online for Onyx, install the app and click execute the "Automation" tab and let us know how you made out.
