Best Home Network NAS
jammerjam writes "My WD 120GB drive got its MBR scrambled so it no longer mounts in my W*ndoze box (I can recover the data so I know that's intact). But now that's made me realize I need to implement my data backup plan. Scouring the Internet I can't find a reliable resource for home NAS solutions. For every positive review I can find a negative that refutes it. My first choice from what I found starts at $1200...I've got $500. Anyone have a suggestion? I'm not looking for enterprise-level storage here — but I do want reliability."
I'd get one of those cheapo walmart linux boxes...stick it in a closet....then just use rsync or rdiffbackup....with a real box you'd have the luxury of being able to add additional storage easy...you can even setup a software raid for extra protection...
... you'll always need backups. Even the most reliable systems will eventually fail. Routine backing up is essential.
You don't need enterprise storage solutions: great. That means that you probably don't need to do nightly backups.
The lesson in you losing your data is not that you needed NAS, but you needed to make better backups.

Try and work out exactly what you're protecting against before you worry about solutions.
Do you want data to survive a hard disk failure? RAID. (Though I make no guarantee that any of these things have implemented RAID terribly well, particularly if a disk fails 2 years later and the replacement you plug in has totally different geometry).
Do you want data to survive your own mistakes? Then use the NAS as a backup for your own PC(s).
Do you want data to survive poor implementation in the firmware? For best results, you'll probably need two totally different devices and some means of keeping them synchronised. (Though a number of Buffallo's Linkstation products can support a separate external USB disk for backup of the NAS itself).
Do you want data to survive a house fire? If you've got immense quantities of data, you'll need a unit you can take offsite. If not, perhaps a subscription-based internet backup provider is the way to go.
"I can't imagine this taking more than half an hour to get working."
Jesus. The number of times I've said that and regretted it.

When your RAID card does die (2 years? 4 years?), what will you do? If that card isn't being made anymore, are you out of luck? Or can a different card read the disks? I don't think they can. I know a few people that ran into this.
With a software RAID, you do lose some performance, but any Linux distro will be able to read the disks. If the OS bugs out (an infrequent occurrence), you might lose a little data, but not a ton... I'm actually not convinced you'll have a good linux distro w/frequent kernel panics anyway. If you lose your card, will you lose it all?

Task Scheduler to copy files from client to a network share? Can't be all that complex to set up a basic data backup routine...
Ubuntu requires you to install Samba. WHS uses windows shares / web server interface.Samba has a pretty easy GUI setup, even in Ubuntu. It's also already installed, I believe.
Ubuntu requires raid hardware or software.Software RAID is already built-in. If you use Fedora instead of Ubuntu, you can use LVM's GUI tools to do all of the dynamic partition sizing goodness.
Ubuntu would not give you Remote Desktop access to your windows machines without configuring Wine, I think.Use the Package manager to install rdesktop, which allows remote desktop access to any Windows box. Done.
Ubuntu requires you to install CVS to get versioning of files, which requires you to actively commit files. WHS automatically saves changes between versions and allows you to step back, all through the nightly automatic backup.Ah, now there's one that you've gotten perfectly correct (IIRC), and why I use Bacula on my home network (which is admittedly not something for the casual user).
You'd have to write your own web service to access the machines from outside the network. You'd also have to configure the router yourself. WHS automatically configures routers (if supported) and has an IIS app that lets you access all machines and WHS content from the internet.I'm not so sure I'd want any un-hardened machine to be accessible from the Internet; esp. a Windows one that both streams media and holds all of my personal data in one easy-to-reach location. That's just begging for a first-class arse-pounding from the first script kiddie to see that you've done that.
This is just a handful. I thought this through, I run a small business (20 hours a week of development) and did my homework before making the decision to buy WHS.I'm sure you probably have... but I don't think you had all the facts at hand when you did. Now know that I'm not knocking your choice at all - if you use something as a beta and like it, and it works for you, cool... but I think that you haven't really looked all too deeply into the alternatives, you know?
Personally, I find that spending $169 for just the OS (when I can get at least an extra hard disk with change left over at that price) to be a bit much. There is also the headaches specific to Windows - the high probability of being targeted, the EULA that says I do it MSFT's way or no way at all, the 'phoning home', the DRM, the extra overhead (I stick with runlevel 3 on my home servers), and the fact that there really isn't much I can tweak on it (at least by comparison)... But then, I do the sysadmin thang for a living - so my needs, skillset, and priorities are a lot different from that of the average home user.
And so it goes... :)
Quo usque tandem abutere, Nimbus, patientia nostra?
RAID is most definitely about reliability and recoverability as well as availability. It all depends on the level you choose. Your argument that multiple disks increases your likelihood of failure is trumped by one simple fact: how do you know that the single drive you buy for the job will be more reliable than the one next to it?
You can't, and that's why using at least something like RAID1 is a smart way to go. When one drive fails, your data doesn't all go with that one drive. I've seen drives from batches fail literally within a couple of days of each other. If you're smart and rebuild offline as soon as a failure occurs, your chances of losing all your data are very small. Reliability engineering is all about probabilities, and the mirroring and parity concepts of RAID facilitate this reliability. The only place where your argument holds sway is on RAID0, and that's a pretty specialized application to be sure.
If you want to swap drives without disassembling the machine, get case with enough 5.25" bays for the drives you need and buy some removable trays for $10 a piece. When one drive fails, you turn a key, pull the tray, swap the drive and back in it goes for a rebuild.
