Huh .... well, I bought a Mirra backup server, and have been blissfully using that for a few years now. It took maybe five minutes to hook up ... works in the background backing up everything on all of my networked computers, and I can even download files through the internet if I really have to have them and can't get to my laptop when I'm on the road.
Maybe it's because I have so many client files on my PC ... but I am as close to paranoid about data loss as it is possible for a person to be. I have, on rare occasions lost data ... but that was when I was setting up new drives on a system and just got stupid (had to reformat a drive before I had a chance to back it up ... lost a long piece done for litigation which I then had to recreate from scratch .... ick).
I also have redundant drives in my system (six 500 GB drives and one 200 GB drive that just holds system files). Those I have to actually push a button to back up (D backs up to E, F to G, H to I), and it's really more of a sync than a backup. My thought there was, if any program or data drive goes belly up on me, all I have to do is remap the twin and I'm back up and running.
Like I said .... paranoid.
