A good backup strategy is the best investment you can make in your computing environment. Data loss sucks and data recovery is expensive. Back when I first started in IT down at the "Big Pharma" company were I work, I was on a first name basis with most of the employees at Ontrack Data Recovery services. So many of our scientists would save critical regulatory data on local drives instead of the network shares they were supposed to place data on, and with the large number of systems we had, I was sending them a drive a week (I managed the contract for data recovery at the time).
We would have 1 or 2 files, maybe a couple of images and stuff that were mission critical and it would cost us upwards of a few thousand dollars to recover the drive, and these were small drives at the time - back when data storage was like gold and the prices of drives reflected it. Now data storage is extremely cheap, so much so that there is little reason not to have double the storage required and backup critical data. The most secure method is still off site and even that today has come down in price with all the internet storage capabilities today.
Fan-fucking-tastic eh? Thanks Western Digital.
