You prevent this by really trusting people (Trust, but verify). Don't screw them over. Treat them better than fairly. Give your employees raises before you give yourself anything.

And do backups. And then backups of those backups.

Yeah, the key is inspiring loyalty and creating a nurturing environment. I loved my first two employers and would go in to either, today, if something I worked on was broken and they couldn't fix it.

That's probably because when my grandmother died, my boss at QueBIT said "Ok, go home, call me when you can work again - however long that takes." There was never a discussion of PTO/HR policy, just human treatment.

Also remember to test restoring your backups or they don't count.
