In Ajax-based sites, there's a constant dilemma: How to get objects rendered in templates? In server side (and output full HTML)?

Backups are important. But usually they are made daily or even less often than this. Quick tip I wish I had known a month ago when my MacBook froze and didn’t boot after a fruitful, productive day: backup all the code in realtime, all the time, with Dropbox.
