Loosing all that data is unforgivable. It shows serious incompetence. Even the most elementary business backs up their data, it is standard procedure.
It is still surprising how many people don't backup their data though. All it takes is a fire / computer theft or hard drive failure and some people have lost their entire photo collections, documents, emails - the lot! All for the sake of cutting a CD/DVD occasionally and keeping an encrypted copy of their data at another location (parents house, friends house etc).
