I frequently comment on people not making backups, and there are always plenty of examples of corporations missing the mark too (here, here, here, and here for example). The Social Networking Weblog has a post up with an offer code for Carbonite1. Not quite sure on the angle for social networking in specific, but it’s good to see somebody else commenting on backups. I’ve been using BackBlaze myself for a while, used it to restore files, and it’s pretty fast too2.
Backups are critical, businesses have a financial responsibility for them, whilst home backups have both financial and sentimental value. Get your backups done, get them tested regularly. There are plenty of options for both.
