I feel VERY strongly about backups. Remember that files that are not backed up in at least 2 other places, are files you do not care about. So whatever backup you decide to use, use something. Generally, unlimited backup for a year runs around $150, well worth it, if you compare that cost to the what it would cost to replace thousands of pictures and documents, not to mention the time. If they could be replaced at all. Below I have listed a few of the plethora of backup solutions out there.
