I'm trying to simplify what I use to backup my venerable NAS. Right now, I basically never bother to...
Since my primary desktop is 99.9% of the time booted up into Linux, my thought is to add a hard disk drive to my desktop. And this way without fanfare I can backup the NAS by simply mounting it and rysnc/rsnapshot/whatever to the hard drive in my desktop.
Here's the thing: I would dislike the noise factor of running a HDD in my desktop, so my thought was to buy essentially a molex extension with a power switch in the middle. I can mount the switch externally, and this way I could power off the drive when I don't have the drive mounted. Sounds simple to me, but is there any gotcha I'm not considering? Of course, I'd want to be sure to not power it off when mounted...
