I am building a multi-site at the moment on CentOS 6.5. I have a question with regard to growing size of data.
1. Which parts in Wordpress are the biggest hard disk consumer, the database(MySQL) or the wp-content folder(I created upload folder in it)?
2. What's the best solution/best practices for such storage problem?
As I am a rookie in Linux and Wordpress, I may need more detailed guidance. Sorry for that and thanks in advance!
