No (Score 1)

I say no, only because I cover my ass anyway. Within quotes that I give to my clients, I always put a clause in there that my company is not responsible for any data loss due to malfunctions, etc, and ultimately their data protection is their own responsiblity. I personally would never destroy my clients data on purpose, so it pretty much covers me. Also, as a side note: people who are doing these things as a profession, alone or with a company, should be insured. I myself have over $1M policy for liablity. I feel safe, and the clients that I service feel safe.
