We have been asked by several clients about online/cloud backup. We highly recommend an offsite backup and now solutions are very affordable, usually about $55/year.
Amaratech recommends:
Backblaze, http://www.backblaze.com
Carbonite, http://www.carbonite.com
Mozy was a fav as well but with a recent price jump, this is solution is not as cost effective.
