NAS device for resilient storage?

That sounds like a lot of hassle to me!
You would have to purchase the hardware - the cloud would be free (depending upon size of backup)
As you say it depends on the size of the backup, my "pictures" folder is over 500gb alone
You would have to physically collect/deliver your harddrive.
This I'll give you, depends on how important your stuff is I suppose.
You would have to remember to run the backup.
It's automated, you can set it to run whenever you want on whatever schedule you want

Not for me.

Nas/raid overcomplicated things - one internal drive for the master copy, 2 or more usb drives, in a rotated backup cycle.

Rather than a server which automatically backs up machines attached to it (waking them up if necessary/possible) and automatically makes a copy of whatever folders you want and puts it on another drive.

It's all automated.

Granted you need to have physical input if you wanted to store a copy off-site, but then you would also need to in your, prehistoric, method.

complicated solution to a simple problem, OP needs to backup 25GB from a to b, and maybe have some version control/redundancy, a portable usb drive or two is the cheapest, simplest, fastest, quietest option.

any backup can be automated.

I'm using TurnKey Linux "Fileserver"
http://www.turnkeylinux.org/

It's debian based and I can get around it a lot eaier than "freenas" and "nas4free"

Also had to manually format my 2 x 3Tb drives since most of the NAS interfaces can't handle formatting 3Tb drive at the moment.

Interesting, I'll take a look at Turnkey Linux.
What type of throughput do you get using SMB and turnkey, is your network switched Gigabit? I'm interested to compare speeds with my network, I can't remember what throughput I get but I can run some tests and provide results.

it's a bog standard BT Home Hub 3 ^_^

Not tried much in the way of throughput testing I'm not needing anything that fast so Wifi is fast enough forwhat Im doing at the moment. As long as it can stream 1080p movie from it I don't care about the speed ^_^ lol

FreeNAS or NAS4Free are pretty good:

http://www.nas4free.org/

I'm running an older build of Nas4Free (the original FreeNAS) and it's great, has a built in Torrent client, FTP, CIFS
Built on an old AMD PC that was no longer needed, bought 3 x 1 TB drives (RAID 5), SATA controller card, turned an unwanted PC into a useful machine for a small price.
I tried a few of the various NAS solutions in VMware first and preferred FreeNAS but there have been many changes and updates since then.

FreeNAS alternatives:

Why go for RAID 5? Especially with only 3 discs. Have a look at http://www.smbitjournal.com/2012/11/choosing-a-raid-level-by-drive-count/

My company has its own servers in a near by datacenter. You don't need a datacenter, although its obvious advantages are 100megabit up and down, but we have a server there with SVN on it, takes incremental backups every hour. It also has complete version control, allows you to check out and work on other machines.

All you'd need is a low powered server and a USB HD with some SVN client like tortoise on it. Even a £30 raspberry pi would probably do, and then have another server (offsite if you want added security) - an £80 microserver would be perfect but any PC built in the last 10 years will do the job (might even be cloud storage SVN solutions if that is what you prefer) put a couple of harddrives in, setup security and firewall rules if needed and away you go.

I'm not sure if you've posted the wrong link but it states that RAID 5 should never be used with spindle drives which is the usual advice these days for RAID 5 arrays. They were popular years ago as they look good on paper but they don't tend to work well in practice due to the problems that can be encountered during rebuilds. It also cannot be used as a backup which is what the OP is looking for.

Yes apparently the odds of a failure on a drive rebuild are very high, and the result is that you plug a new drive in and lose *all* the data. (Apparently the trick when a drive fails is to immediately backup all the data to another drive/set of drives before trying to replace the failed drive).

I found these articles on RAID5 interesting.
