Stupid? Me? Nah,I don't get it ;)

Seriously, I'm planning a new server box and backing up obviously would
pay to to be changed somehow. Maybe yours is one good way.

But really, it's been there for HW failures only. I've always been using
recycled iron for these games I play for fun. So I really do not trust
them. I've lost my mother a few times (sigh) but I only use newish
drives, though. They've been good so far.

I get another new drive about once a year, so the oldest ones are not
that old. As soon as I have 3 identical drives I can spare, I will setup
a RAID 5 system. The problem's been that I keep buying bigger ones all
the time.
Guess I should once get 3 big enough drives in one go.

The next box should also have a good script for smartmontools. If I came
up with one somebody's already made, I'd smile :)
Smartmontools is one helluva piece of software.

As you see here I'm very worried about drives.

But as mentioned elsewhere I'm also one of those having stopped buying
music for some reason. And I have 32 GB of mp3. ;)
