I have only a dim understanding about how a safety clone works...I know that there are symbolic links between items on the SC and the original volume, but that's about it.

I'm running MySQL/PHP, and I'd like to upgrade the MySQL version. When I'm mucking around in the MySQL directiories, am I on the safety clone, or am I "symbolically linked" to the main volume? Put another way, will upgrading MySQL work the same way any other installing works, which is that I affect only the safety clone and then need to reinstall everything again on the main volume?

What about the databases? Do they exist on the main volume and then are symbolically linked in the safety clone, or are there two copies, one on the safety clone and one on the main volume?
