To quote Asif Rehmani (@asifrehmani) from www.sharepoint-elearning.com … “SharePoint Designer is like a really sharp knife. It’s very good at what it does. You might cut yourself. But you don’t stop, just act more carefully.”
With that lesson well learned over my years with SharePoint customization I must say my favorite trick of all is the simple quick copy/paste backup. Any time and every time I’m about to jump off a cliff to dive into SPD coding I perform a Quick Backup:
- Highlight the file
- Ctrl+C (copy)
- Ctrl+V (paste)
- Breathe a sigh of relief
Storage is cheap. Mistakes are not. Time is one of our most scarce resources. Buy some insurance with a Quick Backup!
