How many of you out there routinely backup your data at home? Let's see a show of hands. That few? Are you serious?
Think about it, people. Your thousands of digital photographs could literally be the illustration beside the Webster Dictionary definition of the word "priceless". And to a certain extent, you can include your MP3s or iTunes purchases (if you paid for them - you did, right?). How would you feel if all of that suddenly vaporized in the form of a hard disc crash or something darker like a house fire?
At the corporate level, IT staff and solid backup and/or disaster recovery plans are the ticket. Any company that stores even a modest amount of business data within its walls simply has to have a good plan for what to do when the you-know-what hits the fan. And if they don't, very bad things can happen.
Take the blogging site journalspace.com for example. Their entire online existence along with the writings of all their customers (read: years' worth of irreplaceable data) very quickly disappeared into the void. Their backup strategy was a RAID mirror set, typically two identical hard drives that are exact copies of one another. Somehow the data on the first drive was overwritten, which triggered a similar action on the second drive. In a matter of seconds, everything was gone.
So let this be a lesson to you. And this January, while your willpower to maintain a New Years Resolution is still relatively strong, set yourself one more ... to backup your data.
