Believe me, I've been there!
I've also been saving up for an external drive for backups and hopefully
I can eventually swing for a larger hard drive to put in the home server
for another backup location.
Right now, it's just used to transfer files between me, my wife, and my
son, so it doesn't need to be very large.

My hope is in the next life, not this, so if I HAD to lose all my data
(whether by force or accident matters little) I'm sure the sun will rise
again the next day.
Either way, I'll do what I can to keep what I have.
Thanks for all the info...
