>> It was the company's responsibility (too) that there was no database backup when he wiped it.

I always say "If you fail to prepare, prepare to fail." I'm seeing a pattern here in the OP's behavior that led to him wiping the database and his naive reliance on his former employer to do the right thing before exiting the company. This guy has no clue about how to contingency plan.

As for the company, shame on them, but that kind of douchy behaviour is rampant in startups and small companies. You always need to look out for your own personal financial interests first with startups, no matter how 'collegial' the work environment is.
