Running your own server can be a pain. But it's really nice when things like this happen. I have two servers, the main and the backup. The backup I turn on once every 2 weeks to copy/backup all the hosted media from the main server, do any required updates, then it gets shut down for another two weeks. All this in the case of software or hardware failure, including any virus infections. The main server does a backup to my main desktop PC every night. Then like you Jeff, my PC is backed up to a 2TB external drive once a week. This drive is unplugged unless it's being used for the backup so the ransom ware viruses can not encrypt it if I get that nasty bug. On top of all that, I create an image of my boot OS drives of all my computers (all data is stored on separate D: drives) so that if anything were to happen, I can simply install a new drive, and restore from a known good backup. All three of these computers D: drives are running a Raid 5 array so that in the event of a drive failure, no data is lost.
Yea, I'm a bit of a computer geek. Started when I was 14 (around 1975) with my Commodore 64. Could not leave well enough alone and added a 20mb (that was huge back in the day) hard drive to it. Look where all that lead to, well, and my interest in Mustangs....
