I would suggest making backups of anything related to digital information that you cannot live without if you store it locally. I work in IT and DR (Disaster Recovery) always sucks. Especially when an accountant's PC crashes with the company's books stored on it without telling anyone he stored them locally. Data redundancy is always recommend, also keeping that redundant data up to date. It would suck if you backed up your wallet with 1BTC, receive more and then lose the dive. Your stuck with the 1BTC again.
