Just another reason to jump to Ghost! I didn't know that ZFS meant that - you learn something every day (and I've been doing this for nearly four decades now!) I'll certainly be taking your advice on the de-duplication fiasco! in fact, my local store for mission critical files is quite modest - 120 gB SSD - which is lean but quite sufficient. All the production and backups goes straight to more traditional drives: but my fear (and experience) is that it's usually the primary, pre-backup that gets hit during an outage, crash, etc. This is where ZFS comes into its own, for me anywhere. Journalling never seemed to live up to the promises made of it.
I got this machine when my Mac (under two years old) decided it was going to take its ball and go home... long story but it really was hardly used and I wasn't the happiest of bears as you might imagine. My 20+ year old Chinese made oscilloscope which I still occasionally need still works - the week I'm having though, I probably just nixed that too.
I'm something of a recycler - most of my machines are refurbs/recons and several are donations which is why I'm big into the GNU+Linux and BSD scene. I donate my old ones to people in greater need and GNU/BSD is usually a far better bet unless folks need things like iTunes and we all know what that means, right?
This particular beast came by way of these guys in England (
http://www.bargainhardware.co.uk/ ) and I can heartily recommend them the machines are obviously used and many come from data centers, etc. but considering what I paid for this it's an absolute beast. I honestly don't care if the case has the odd nick and scratch, it's a workhorse!
When the piggy bank allows, I'll certainly be getting one or two more similar machines to make a small render farm.
I love this idea of copy-on-write though - it's such a shame we can't get it for pico-servers like the Raspberry PI which powers my DietPi-powered backup system. It's a trade off, I know, but having a backup online 24/7 that doesn't cost me a new PC every year in running costs is good for me and great for the environment.
