Microsoft unveils new file system for Windows

Microsoft has unveiled its new file system, saying it will first arrive in Windows Server 8.
The Resilient File System (ReFS) builds on the existing NTFS, and is therefore largely compatible with it.
"We didn't start from scratch, but reimagined it where it made sense and built on the right parts of NTFS where that made sense," said Surendra Verma, a storage development manager, in a post on the Windows 8 blog.
Verma explained that ReFS will remain compatible with NTFS, keeping key features while "deprecating" less successful ones.
Feature
Windows 8: the game changer"ReFS inherits the features and semantics from NTFS including BitLocker encryption, access-control lists for security, USN journal, change notifications, symbolic links, junction points, mount points, reparse points, volume snapshots, file IDs, and oplocks," Verma said, while ditching "named streams, object IDs, short names, compression, file level encryption (EFS), user data transactions, sparse, hard-links, extended attributes, and quotas".
ReFS will be accessible through the same file-access APIs, meaning any system that can access NTFS volumes will work with the new system.
Resiliency - if it wasn't clear from the file system's name - is a major focus, with all metadata verified using checksums and no longer written in place, to avoid "torn writes" if interrupted, such as by a power outage.
"In addition, we have added an option where the contents of a file are check-summed as well," said Verma. "When this option, known as 'integrity streams', is enabled, ReFS always writes the changes to a location different from the original one. This allocated-on-write technique ensures that pre-existing data is not lost due to the new write."
Storage spaces
ReFS is designed to work with Microsoft's Storage Spaces, a new system which uses virtualisation to create storage pools to better manage data.
The two systems can be used separately, but together they add more features, notably allowing Storage Spaces to fix corrupted files uncovered by ReFS using mirrored copies, and "scrubbing" metadata to ensure it's correct. "Scrubbing involves reading all the redundant copies and validating their correctness using the ReFS checksums," said Verma. "If checksums mismatch, bad copies are fixed using good ones."
ReFS will initially only be available with Windows Server 8, and then only for storage systems. It will eventually be rolled out to Windows 8 client and then as a boot volume, but Microsoft didn't reveal a timeline.
Well, at least they are not touting ...
... that ridiculous 'digital soup' they they were threatening us with a few years ago.

The Vista Route Again?
Call me racist, although I am of Asian origin, but the guy’s name makes me apprehensive. I don’t see why they don’t employ home grown US technicians or architects to think-up these fundamental changes. If the guy is a US citizen, then I apologize profusely. If a US company however, has farmed out its brain-ware to a 3rd world culture, even though it may have the University credentials to boot, I think we’re going down the Vista route again. That’s a Route 66 of a different kind!

That's a fairly unhealthy mix of xenophobia and racism.

Racist?

Honest
Isn't the best in the world usually better than the best in your country?

It was home grown technicians that came up with Y2K :P

That little word
'Largely' compatible? I can see that coming back to bite someone on the backside.

WTF happened to WFS?
Is this some ploy to pretend that Windows File System was never on the cards? Windows has needed an update to the workstation file system for years, and now we are being bypassed?

That's not xenophobic...
Or not just xenophobic, but also parochial (can't get better than American), misguided (this guy is talking about ReFS so he must be the chap who came up with it - singlehandedly, of course), ignorant (shame that there are no American technicians thinking of these fundamental changes) and just plain nonsensical (if he is a U.S. citizen that makes everything ok).
Rest easy, vic_ago - I won't call you racist!

Are you also under the impression that being Asian means that you cannot be racist?

Generally speaking, in the mentality of Apple: 1)find the best solution first, then charge people the earth to use it. 2)MS it seems, by using "highly-qualified" 3rd world boffins, seems to be using the cheapest labour; finding what these “highly qualified” 3rd world technicians can come up with as the best solution; then charging people for the pleasure of fixing it for them when it goes wrong.
Ah, actually, the MS biz-model makes more sense than Apple’s! I just answered my own question. ;(

Hurrah for capitalism! (not)
It seems Microsoft has learnt a lot from XP. Building a relatively benign OS is not as profitable as building one that’s touted as the best, but in actual fact is riddled with holes, and needs constant fixing. The ploy will only work however, if people can be fooled into believing whole heartedly, the motto “New is Best.”
I’m in two minds since I’m a user and a fixer too. As a user, I don’t want un-anticipated screens black or blue, with just a cursor flashing, spoiling my Youtube viewing randomly. But as a fixer, I know I can make a good living fixing the problems that hit people.
I’m pretty sure Microsoft has come to acknowledge this by now. I don’t think the idealism of Bill still hold true in its Boardrooms. This new file system, whilst being touted as an improvement, will be far from the ideal solution. It will have cack built in and for deliberate economic reasons. Hurrah for capitalism! (not)

Yet another bodge
Ask anyone who's made the painful transition from Novell NetWare to Microsoft Windows as a server OS ("What do you mean, I can't salvage deleted files?" "How come the failover cluster takes three minutes to fail over instead of three seconds?" "Why's this grant-access job taking so long?" "Why can't I tell what folders this user has access to any more?"), NTFS needs to be put to rest, not patched up with more junk code. It'd be cheaper for MS to buy Novell from Attachmate and build upon a dedicated server platform rather than a desktop OS on steroids.

Oh god no
MS - Please don't foist this on consumer desktops! It is obvious from the technical description lists that it is intended for servers, and that is exactly where it shoud stay. NTFS works perfectly for home desktops, and as with most new MS products it is unsafe/unusable for the first 8-12 months, until all the failures have been reported by the poor users having calamities, and then for MS to slowly fix said problems. Certainly not something for home users to cope with! Why can't they just licence existing proven technologies from Novell or Apple? Apple don't like to give away the gems, but they can do deals.

What a load of negative comments! Lets be open- minded and give the new file system a fair trial.Be open to change.I use and like Windows XP,but if someone comes up with anything better I'm willing to give it a go.Let's stop bashing Microsoft.They have given the world operating systems and other software that we all use every day.

Innovation not Frustration - walker46
We’re PC users and love our PCs: and we prefer Microsoft to other OS brands. That’s why we seem hard on this new fangled file system. We just don’t like the idea of more tinkering with Systems we’ve come to know and trust. It seems like MS has run out of ideas and has to keep re-inventing the wheel on a yearly bases; as the case with Office. Problem with that is – if you keep trying to re-invent the wheel – you’ll come up with a square version – such was the case with Vista. MS keeps changing for changing sake and forget what the user needs. We don’t need more hassle, updates and Service Packs!

(Just a Thought)
IF MS really wants to make a leap forward, it should device less intrusive, more discrete means of updating Windows. That was ok in the days of XP. But now, constant updates just makes the product look like it’s broken. All this constant version updates and revisions 1.0, 1.02, 1.06 1.XX – looks so damn primitive. Can you imagine Tom Cruise in Minority Report using those fancy graphic interface – then he has to stop – as a message says – “Windows is updating – please wait.” Everyone would start laughing! Even Apple is guilty of these constant updates.
What you should have is a Shadow Operating System running in the back ground; and that should be the one that gets busy being updated - leaving you to use the live OS - unmolested. Then at the next boot up, the Updated Shadow OS – is the one that is Booted up. You heard it here first – from David S….
