I am amazed at how much the price of external hard drives has fallen. I’ve just ordered two Western Digital 1TB drives for under £60 each from Amazon. I’m going to use them for offsite storage for backups. Dave (Red Yeti) made a good post about offsite backups. At the moment I’m not keen to use a web-based service, so I’ll back up to an external hard disk and rotate the disks to somewhere safe.
Currently my entire computer is backed up to my home server, which I bought primarily to store my CDs (about 450 ripped so far) but that is no protection against a fire. I will also transfer copies of my ripped CDs as a backup, hence a disk large enough to cover all eventualities. As Dave says, how would you feel if all your pictures were lost. I’m now in extreme disaster planning mode!
