The Message That Made Me Actually Understand My Own Server

Sometimes the best lessons don't come from a course or a bug you were already hunting. They come from someone else asking a simple question you assumed you already knew the answer to. A colleague I was sending website files to messaged me: the database dump looked unusually big at 45MB, and he wanted to know why before uploading it. My first instinct was that 45MB was completely normal for a WordPress site. But "normal" isn't proof, and he was right to ask. I exported the database and started checking table by table. The answer was sitting right there in wp_posts: 1,749 old revisions, all generated automatically while I was building and testing custom plugins throughout the site, accounting for 26MB on their own. While preparing the full website files for transfer, I found something even bigger. Backup plugins had quietly stored over 22GB of old duplicate backups directly inside the web root, meaning I was almost zipping the entire site twice without realizing it. I safely removed the old revisions and expired temporary cache data, none of which affected any live page, plugin, or setting. I excluded the old backup folders from the final package and compressed the database properly. The result: Database: 45MB down to 12MB Website package: 25GB down to 486MB Everything active: 100% intact What I Learned A question that sounds like a complaint is often just someone asking you to verify your own work, and that's a good thing. Bloat builds up silently. Revisions, transients, and old backups don't announce themselves. Being able to explain a number with real data is what separates guessing from engineering. Looking Ahead This wasn't a big dramatic bug. It was a small, honest question that pushed me to actually understand what my server was doing instead of assuming it was fine. That's a habit I want to keep building.
