Get 2 VMs for FREE, forever! Free Trial Now! Free Trial Now! Get 2 VMs for FREE, forever! of August, 2012 Microsoft released Windows Server 2012Р Р†the sixth release on the Windows Server product family. On May 21
2013, Windows Server 2012 R2 was introduced and is particularly now the latest version of Windows Server on the market. Microsoft has released four different editions of Windows Server 2012 varying on price, licensing and features. These four editions of Windows Server 2012 R2 are: Windows 2012 Foundation edition, Windows 2012 Essentials edition, Windows 2012 Standard edition and Windows 2012 Datacenter edition.
LetР Р†s take particular notice at each Windows Server 2012 edition and what they've got to offer.
Users may download the free Windows Server 2012 R2 Licensing Datasheet in this Windows Server Datasheets Useful Resources download section, that gives a detailed overview in the Licensing for Windows Server 2012 and features extremly useful information for the various Windows Server 2012 edition, examples regarding how to calculate your licensing needs, Virtualization instances based on every edition, server roles, common questions answers, plus more.
This edition of Windows Server 2012 is targeted towards small enterprises of as much as 15 users. The Windows Server 2012 R2 Foundation edition comes pre-set up on hardware server with single physical processor or higher to 32GB of DRAM memory. Foundation edition may be implemented in environments where features for example file sharing, printer sharing, security and remote access are expected. Advanced server features including Hyper V, RODC Read Only Domain Controller, data deduplication, dynamic memory, IPAM IP Address Management, server core, certificate service role, hot add memory, windows update services and failover clustering are certainly not available inside Foundation edition.
The Windows Server 2012 R2 Essentials edition could be the next step up, also geared towards small business owners of as much as 25 users. Windows Server 2012 R2 Essentials edition is easily obtainable in retail stores all over the world making it possible for businesses to set up the new main system without necessarily purchasing new hardware. Similar on the Foundation edition, the Essentials edition won't support many advanced server features, but it really does provide support of features like Hyper V, dynamic memory and hot add/remove RAM.
Windows Server 2012 R2 Essentials edition can operate a single illustration showing virtual machine on Hyper V, an element that was not for sale in Windows Server 2012 Essentials non-R2 edition. This single virtual machine instance might be Windows Server 2012 R2 Essential edition only, seriously limiting the virtualization options but allowing companies to start with exploring the benefits with the virtualization platform.
The Windows Server 2012 R2 Standard edition of windows server is utilized for medium to large companies that require other functions not found in the Foundation Essential edition. The Standard edition is in a position to support a limitless amount of users, providing the required user licenses are already purchased.
Advanced features for example certificate services role, Hyper V, RODC Read Only Domain Controller, IPAM IP Address Management, Data deduplication, server core, failover clustering plus more, are for sale to Windows Server 2012 Standard edition. We should realize that the Standard edition supports approximately 2 Virtual Machines.
The Windows Server 2012 R2 Datacenter edition could be the flagship product developed to meet yourwants of medium to large enterprises. The major difference between Standard and Datacenter edition is the Datacenter edition allows the development of unlimited Virtual Machines and is particularly therefore appropriate for environments with extensive utilization of virtualization technology.
Before buying the Windows Server 2012 computer, it's very important to understand the real difference between various editions, the table below shows the visible difference between the four editions of Windows Server 2012:
Retail, volume licensing, OEM
250 RRAS connections, 50 IAS connections, and two IAS Server Groups
Either in 1 VM or 1 physical server, however, not both at once
Yes, Must be reason behind forest and domain
The standard and datacenter editions of Server 2012 support Client Access License CAL or Device Access License DAL licensing model. A CAL license is a member of a user whereas a DAL license is part of device computer. For example, a CAL assigned to a person, allows just that user to gain access to the server via any device. Likewise, in case a DAL is bestowed upon particular device, then any authenticated user using device is allowed gain access to the server.
Assume an atmosphere with Windows Server 2012 R2 standard edition plus a total of 50 users and 25 devices workstations. In this case, you can purchase either 50 CAL licenses to pay the 50 users we have now or alternatively 25 DAL licenses to pay the total volume of workstations that need to get into the server. In this scenario, purchasing DALs is usually a more cost-effective solution.
If however we'd 10 users having a total of 20 devices, e.g 2 devices per user workstation laptop, it more become more cost effective to buy 10 CAL licenses.
Windows Server 2012 Foundation is accessible to OEMs Original Equipment Manufacturers only and for that reason can only be purchased with the time of choosing a n new hardware server. Windows 2012 Foundation edition supports approximately 15 users. CALs or DALs are certainly not required for that Foundation edition servers. In addition, Foundation edition owners cannot upgrade with other editions. The maximum volume of SMB Server Message Block or file sharing connections for the server is 30. Similarly, maximum quantity of RRAS Routing and Remote Access Service and RDS Remote Desktop Service connections is 50.
The Essential edition of server 2012 is accessible to OEMs when you buy new hardware and as well at retailers. The user limit of the server edition is 25 and device limit is 50. This means that only 25 users amongst 50 computers can access the Windows Server 2012 Essentials edition. For example, you've got 20 users rotating randomly amongst 25 computers accessing the Server 2012 Essentials edition, without problem. CALs or DALs usually are not required for Windows Server 2012 Essentials edition because only 25 users can access the server.
A common question at this point is what happens if the organization expands and increases its users and computers?
In these cases Microsoft offers upgrade path allowing organizations to upgrade to your Windows Server 2012 Standard or Datacenter edition license and perform an in-place license transition. Once the transition is complete, an individual limitation, along with features are unlocked without requiring migration or reinstallation from the server.
Companies upgrading into a higher edition of Windows 2012 Server needs to keep in mind that it'll be necessary to get the required level of CALs or DALs in accordance with their users or devices.
Administrators is going to be happy to be aware that it is also possible to downgrade the Standard edition of Server 2012 towards the Essentials edition. For example, you possibly can run Essential edition of Server 2012 as virtual machine utilizing 1 of 2 available virtual instances in Standard edition as shown within the figure below. This eliminates the needs to buy Essential edition of Server 2012.
With the making of Windows Server 2012 Essentials R2, Microsoft has updated its licensing model. Unlike Windows Server 2012 Essentials non-R2, you are able to now attempt a single illustration showing a virtual machine.
The Hyper-V role and Hyper-V Manager console are included with Windows Server 2012 R2 Essentials. The server licensing rights have already been expanded, allowing you to set up an type of Essentials on your own physical server to own the Hyper-V role with none from the other roles and features on the Essentials Experience installed, plus a second illustration showing Essentials as being a virtual machine VM on that same server because of the Essentials Experience roles and features.
The license of Standard and Datacenter edition is founded on sockets CPUs and CAL or DAL. Definition of an socket can be a CPU or physical processor. Logical cores are certainly not counted as sockets. A single license of Standard and Datacenter edition covers approximately two physical processors per physical server. CAL or DAL licenses are then required in order that clients/devices can access the Windows server. Standard edition allows approximately 2 virtual instances whilst the Datacenter edition allows unlimited volume of virtual instances.
For example, a Windows 2012 Server R2 Standard edition set up on a physical server with one socket CPU can support as much as two cases of virtual machines. These virtual machines could be Server 2012 R2 Standard or Essentials edition. Similarly, in case you install a Windows Server 2012 R2 Datacenter edition, then you are able to install a limitless amount of number of virtual machines.
Scenario 1 : Install Server 2012 Standard/Datacenter Edition on the server box with four physical processors and 80 users.
In this scenario, we will likely be required to get two Standard/Datacenter Edition licenses just because a single license covers as much as two physical processors, plus 80 CAL licenses so our users can access the server resources.
Scenario 2 : Install Server 2012 Standard Edition on an actual physical server with 1 physical processor, running 8 cases of virtual machines. A total of 50 users will likely be accessing the server.
Here, four Server 2012 Standard edition licenses are expected and 50 CALs or DALs. Remember that one particular Standard edition license covers approximately two physical processors or more to two cases of virtual machines. Since the requirement is to own 8 cases of virtual machines, we require four Standard edition licenses.
If we thought we would use the Datacenter edition on this scenario, one particular license with 50 CAL could be enough to hide our needs, for the reason that Datacenter edition license supports a large number of virtual instances or higher to two physical processors.
MicrosoftР Р†s Windows Server 2012 is undoubtedly an attractive server-based product built to meet the demands of promising small to large enterprises and it has a very flexible licensing model. It is very important thoroughly understand the licensing options and supported features on each on the 4 available editions, before proceeding along with your purchase Р Р†a tactic which will help ensure cost is kept well within the allocated budget even though the companyР Р†s needs are fully met.

The Storage Team Blog about file services and storage features in Windows and Windows Server.
Hi, this really is Scott Johnson and Im a Program Manager about the Windows File Server team. Ive been at Microsoft for 17 several Ive seen lots of cool technology in this time. Inside Windows Server 2012 we now have included quite a cool new feature called Data Deduplication which allows you to efficiently store, transfer and backup less data.
This may be the result of a comprehensive collaboration with Microsoft Research and after 24 months of development and testing now we have state-of-the-art deduplication that utilizes variable-chunking and compression and it might be applied to most of your data. The feature is ideal for industry standard hardware which enable it to run over a very small server with as little being a single CPU, one SATA drive and 4GB of memory. Data Deduplication will scale nicely when you add multiple cores and extra memory. This team has some on the smartest people I have caused at Microsoft therefore we are all very excited with this release.
Hard disk drives increasingly becoming bigger and cheaper annually, why would I need deduplication? Well, sixty growth. Growth in details are exploding a lot that IT departments everywhere should have some serious challenges fulfilling the demand. Check out the chart below where IDC has forecasted that people are beginning to have massive storage growth. Can you create a world that consumes 90 million terabytes in a single year? We are about 1 . 5 years away!
Foundation Solutions for Content Delivery, Archiving and Big Data, doc 231910, December 2011
This new Data Deduplication feature can be a fresh approach. We just submitted a Large Scale Study and System Design paper on Primary Data Deduplication to USENIX to get discussed with the upcoming Annual Technical Conference in June.
We analyzed many terabytes of real data inside Microsoft to obtain estimates with the savings you should expect in case you turned on deduplication for several types of internet data. We focused about the core deployment scenarios that individuals support, including libraries, deployment shares, file shares and user/group shares. The Data Analysis table below shows the standard savings we were capable to get from each kind:
Microsoft IT has become deploying Windows Server with deduplication with the last year plus they reported some actual savings numbers. These numbers validate our analysis of typical details are pretty accurate. In the Live Deployments table below we've got three popular server workloads at Microsoft including:
A build lab server: These are servers that develop a new version of Windows everyday so that we are able to test it. The debug symbols it collects allows developers to examine the exact brand of code that corresponds for the machine code a system is running. There are many duplicates created since we simply change a small volume of code on the given day. When teams release a similar group of files with a new folder every single day, there are plenty of similarities every day.
Product release shares: There are internal servers at Microsoft that hold every product weve ever shipped, atlanta divorce attorneys language. As you might expect, whenever you slice up, 70% with the data is redundant and may be distilled down nicely.
Group Shares: Group shares include regular file shares which a team might use for storing data and includes environments designed to use Folder Redirection to seamlessly redirect the trail of a folder just like a Documents folder to your central location.
Below is usually a screenshot from the revolutionary Server Manager Volumes interface on of one with the build lab servers, notice the amount of data that people are saving on these 2TB volumes. The lab is saving over 6TB on each of those 2TB volumes and theyve still got about 400GB free on each drive. These a few pretty fun numbers.
There is usually a clear revenue that may be measured in dollars when working with deduplication. The space savings are dramatic along with the dollars-saved may be calculated pretty easily whenever you pay from the gigabyte. Ive had many individuals say that they desire Windows Server 2012 for this purpose feature. That it could make them delay purchases of brand new storage arrays.
1 Transparent and simple to use: Deduplication is usually easily installed and enabled on selected data volumes using some seconds. Applications and users will not understand that the data is transformed about the disk and when an individual requests information, it will likely be transparently served up straight away. The file system as being a whole supports all on the NTFS semantics that you will expect. Some files usually are not processed by deduplication, like files encrypted while using the Encrypted File System EFS, files which can be smaller than 32KB or those which may have Extended Attributes EAs. In these cases, the interaction together with the files is entirely through NTFS along with the deduplication filter driver won't get involved. If personal files has an alternate data stream, the primary data stream are going to be deduplicated and also the alternate stream are going to be left within the disk.
2 Designed for Primary Data: The feature could be installed in your primary data volumes without interfering using the servers primary objective. Hot data files which might be being written to will probably be passed over by deduplication before file reaches a specific age. This way you may get optimal performance for active files and great savings about the rest on the files. Files that fulfill the deduplication criteria are known as in-policy files.
a. Post Processing : Deduplication is not from the write-path when new files appear. New files write directly to your NTFS volume and also the files are evaluated by information groveler using a regular schedule. The background processing mode checks for files that happen to be eligible for deduplication every hour and you may add additional schedules if you may need them.
b. File Age: Deduplication incorporates a setting called MinimumFileAgeDays that controls how old information should be before processing the file. The default setting is 5 days. This setting is configurable by anyone and could be set to 0 to process files regardless of what age they are.
c. File Type and File Location Exclusions: You can tell the machine not to process files of your specific type, like PNG files that have great compression or compressed CAB files which could not gain from deduplication. You may also tell the machine not to process a specific folder.
3 Portability: A volume which is under deduplication control is undoubtedly an atomic unit. You can backup the volume and restore it to an alternative server. You can rip it out of 1 Windows 2012 server and move it to a new. Everything that's required gain access to your information is located within the drive. All from the deduplication settings are maintained about the volume and is going to be picked up through the deduplication filter when the actual is mounted. The only thing that isn't retained within the volume are definitely the schedule settings which can be part from the task-scheduler engine. If you move the volume with a server that isn't running the Data Deduplication feature, you will be capable of access the files that have never been deduplicated.
4 Focused on using low resources: The feature was created to automatically yield system resources towards the primary servers workload and back-off until resources are offered again. Most people agree that their servers work to do and also the storage is only facilitating their data requirements.
a. The chunk stores hash index is built to use low resources and lower the read/write disk IOPS to ensure it can scale to large datasets and deliver high insert/lookup performance. The index footprint is incredibly low at about 6 bytes of RAM per chunk and it also uses temporary partitioning to compliment very high scale
c. Deduplication jobs will verify that there's enough memory to perform the work of course, if not it is going to stop and try again in the next scheduled interval.
d. Administrators can schedule and run any on the deduplication jobs during off-peak hours or during idle time.
5 Sub-file chunking : Deduplication segments files into variable-sizes 32-128 kilobyte chunks utilizing a new algorithm created in conjunction with Microsoft research. The chunking module splits folders into a sequence of chunks inside a content dependent manner. The system utilizes a Rabin fingerprint - based sliding window hash for the data stream to distinguish chunk boundaries. The chunks provide an average dimensions of 64KB and in addition they are compressed and placed to a chunk store located inside a hidden folder in the root in the volume known as the System Volume Information, or SVI folder. The normal file is replaced with a small reparse point, which includes a pointer with a map of all the info streams and chunks needed to rehydrate the file and serve this when it truly is requested.
After being processed, the files at the moment are reparse points with metadata and links that could indicat where the file info is located inside chunk-store.
6 BranchCache : Another benefit for Windows would be that the sub-file chunking and indexing engine is shared with all the BranchCache feature. When a Windows Server for the home office is running deduplication the info chunks seem to be indexed and so are ready to become quickly sent on the WAN as needed. This saves a bunch of WAN traffic into a branch office.
Deduplication creates fragmentation with the files that are with your disk as chunks could end up being spread apart this also causes increases in seek time because disk heads must move about more to assemble all the necessary data. As each file is processed, the filter driver actively works to keep the sequence of unique chunks together, preserving on-disk locality, therefore it isnt a totally random distribution. Deduplication also carries a cache to prevent going to disk for repeat chunks. The file-system has another layer of caching that is certainly leveraged for file access. If multiple users are accessing similar files simultaneously, the access pattern will enable deduplication to speed things up for all with the users.
There aren't noticeable differences for opening an Office document. Users will never be aware that the underlying volume is running deduplication.
When copying an individual large file, we have seen end-to-end copy times that may be 1.half a dozen times what it takes with a non-deduplicated volume.
When copying multiple large files concurrently we have seen gains because of caching that can induce the copy time being faster by nearly 30%.
Under our file-server load simulator the File Server Capacity Tool set to simulate 5000 users simultaneously accessing the system we merely see in regards to 10% decline in the variety of users that might be supported over SMB 3.0.
Data could be optimized at 20-35 MB/Sec within just one job, which comes over to about 100GB/hour for 1 2TB volume using 1 CPU core and 1GB of free RAM. Multiple volumes may be processed in parallel if additional CPU, memory and disk resources can be purchased.
Even with RAID and redundancy implemented in your metabolism, data corruption risks exist because of various disk anomalies, controller errors, firmware bugs as well as environmental factors, like radiation or disk vibrations. Deduplication adds to the impact of just one chunk corruption since a common chunk is usually referenced using a large volume of files. Imagine a chunk that may be referenced by 1000 files is lost due to your sector error; you'd probably instantly suffer one thousand file loss.
Backup Support: We have support for fully-optimized backup with all the in-box Windows Server Backup tool and we've got several major vendors taking care of adding support for optimized backup and un-optimized backup. We use a selective file restore API to permit backup applications to tug files from an optimized backup.
Reporting and Detection : Any time the deduplication filter notices a corruption it logs it inside event log, so it may be scrubbed. Checksum validation is completed on all data and metadata if it's read and written. Deduplication will recognize when data which is being accessed has become corrupted, reducing silent corruptions.
Redundancy : Extra copies of critical metadata are made automatically. Very popular data chunks receive entire duplicate copies whenever it truly is referenced 100 times. We label this area the hotspot, which can be a collection with the most popular chunks.
Repair : A weekly scrubbing job inspects the presentation log for logged corruptions and fixes the info chunks from alternate copies whenever they exist. There is also an optional deep scrub job available that will walk all over the country data set, searching for corruptions and yes it tries to fix them. When having a Storage Spaces disk pool which is mirrored, deduplication will reach over for the other side on the mirror and grab the excellent version. Otherwise, the data may have to be recovered at a backup. Deduplication will continually scan incoming chunks it encounters looking for your ones that could be used to fix a corruption.
Well, the Data Deduplication feature doesnt do everything with this version. It is just available in certain Windows Server 2012 editions and possesses some limitations. Deduplication was intended for NTFS data volumes and it doesn't support boot or system drives and can't be used with Cluster Shared Volumes CSV. We dont support deduplicating live VMs or running SQL databases. See how to determine which volumes are candidates for deduplication on Technet.
To aid inside evaluation of datasets we made a portable evaluation tool. When the feature is installed, is installed to your WindowsSystem32 directory. This tool is usually copied and operated with Windows 7 or later systems to discover the expected savings that you'd get if deduplication was enabled over a particular volume. supports local drives plus mapped or unmapped remote shares. You can run it against an isolated share on the Windows NAS, or even an EMCNetApp NAS and compare the savings.
I feel that this new deduplication feature in Windows Server 2012 will likely be very popular. It may be the kind of technology that folks need and I cant wait to discover it in production deployments. I would love to find out your reports for the bottom with this blog of the amount hard disk space and funds you saved. Just copy the output with this PowerShell command: PS Get-DedupVolume
30-90% savings could be achieved with deduplication on most forms of data. I have a very 200GB drive that I keep throwing data at now it has 1.7TB of knowledge on it. It is simple to forget that it is usually a 200GB drive.
Deduplication is easy to put in and the default settings wont permit you to shoot yourself within the foot.
Deduplication works difficult to detect, report and repair disk corruptions.
You can experience faster file download times and reduced bandwidth consumption more than a WAN through integration with BranchCache.
Try the evaluation tool to see just how much space you'd probably save when you upgrade to Windows Server 2012!
Thank you, your comment requires moderation so it usually takes a while to look. Close
Very great! So this is really a complete overhaul with the items SiS was/is if I follow correctly. Also, if I m not mistaken, while SiS worked more or less for the duplicate file level, this goes deeper and de-dupes chunks of identical data in one or more different files?
Yes, Dedup in Windows 8 works at sub-file level. Hence if your completely different files eventually share some chunks, precisely the same chunks are stored one time.
Some fantastic stuff in here!
There are a few things that still remain unclear in my experience, perhaps you are able to shed a light upon it:
Will it assist bitlocker?
Will it develop dynamic disks? mirror volumes etc.
What takes place when I go on a drive with DD enabled and plug it into machine with older main system like 2008r2? Especially in situation when non-deduplicated data could be bigger than drive real capacity.
DFS-R Support: Yes, there may be interoperability with DFS-R. Optimizing or un-optimizing a file will not likely trigger a re-replication, considering that the file didn t change. DFS-R will still use RDC for over-the-wire savings instead of the chunks inside chunk store. The files is usually optimized using deduplication around the replica if it truly is running Windows Server 2012.
Bitlocker Yes, Bitlocker sits below us. Deduplication and NTFS dont understand that there is encryption around the disk and they also function normally.
Dynamic Disks Yes. You can still create Dynamic Disks and hang up NTFS volumes in it. NTFS volumes will surely have deduplication applied provided that it isn t system, boot, etc.
The down-level OS experience is briefly mentioned inside Portability section above. You can only browse the files that have never been processed by Deduplication.
Thank you for answering that DFS-R question but to bad I cant take advantage on the chunks if all replicated members use deduplication.
Just slightly scenario, lets imagine I possess a excel file that may be 200mb which is deduplicated it occupy around 30mb on disk, an end user open it and change 10mb of internet data in it and save it. If I obtain it correctly the file not occupy 40mb on disk at least before next optimization pass, am I right?
And a last question Hyper-V hosts is listed inside the not good candidates for dedup. Why is that? Because on the performance impact or for the reason that vhd files are lock from the hypervisor and this optimizations would want the VM to become offline to achieve success.
Must with the data with a servers system partition is static it might definitely take advantage of deduplication.
Can I control memory cache for Dedup, File Server feature like CSV memroy cache?
Nice write-up, I happen to be experimenting with dedupe on windows server 8 beta, I had deduped a 320GB Disk SATA, I then removed it off my Windows Server 8 Beta Computer and Plugged that drive whilst it was deduped onto my new Windows Server 2012 Box.
On the second-box, deduped drive was coming as Foreign Disk under Disk Management, I selected Import Foreign Disks plus it came up fine.
Now the interesting part, simply because this drive and it also s data was de-duped in my previous Windows Server 8 Box, I seen that for files, I can t open them, I can t open a couple of photos I had with this and some other file types, videos were was obviously a bit
I then installed the Deduplication feature under file services role and once I did a powershell Get-DedupeVolume, it showed me the precisely the same drive and after this I was in a position to access all data that was surely not setting up before installing the dedup role.
Like in SIS on windows 2003R2 Storage Server till 2008 Storage server, un-linking had not been very clean, I think this dedup feature is much more stable and
Your thoughts will probably be very helpful!!
Hi Scott, I use a Server 2012 RC hyper-v host that has a Server 2012 RC hyper-v guest upon it.
The guest is running DFS replication and Deduplication.
Using DFS-R we replicated roughly 250 GB of internet data; the vhdx grew to 275 GB needless to say.
We then applied deduplication along with the volume shrunk by roughly 50% to 125 GB yay!.
Shut about the guest and ran a Compact operation about the vhdx planning on shrink - it remains at 275 GB.
This effectively negates any benefit to your deduplication - could there be something special we'd like to because of actually reclaim this space and shrink the vhd?
This is surely an interesting implementation on the OS. Below include the results from my small server enviornment. This is certainly using real data, on live servers.
Drive T: contains my applications, drivers, along with ISO s, pictures, music, and roaming profiles.
I suspect my results will be about typical instead of test enviornments where precisely the same files are copied many times. From my understanding this will not have a considerable deduplication percentage inside a production enviornment a great deal as an archivingbackup enviornment. I can see if you could have a bunch of archived VHD s this could be capable of save space, but even more may be realized when it comes into a backup enviornment.
Compressed video s and music on the whole have a lots of variation, so I would expect there to get minimal savings at their store.
If your company is inside habit of duplicating files and modifying a small portion say PowerPoint files this could be a sizable savings in those instances.
For your excel file example, the treatment depends on how excel updates the file with 10MB of extra data. If excel writes to some new file of size 110MB then deletes the initial file and renames the brand new file to your original file, the device will consume 140MB. The 30MB storage could possibly be reused when the modern file is deduplicated or can be reclaimed when gargage collection operates. Eventually after deduplication and garbage collection runs, the excel file should consume 40MB or less.
If excel simply appends 10MB to your original file, then the device will consume 40MB once the append. When the file is re-deduplicated, perhaps it will consume a lot less than or similar to 40MB, depending for the deduplication and compression ratio.
For Hyper-V host, yes, deduplication just isn't recommended on account of performance impact also, since deduplication requires information not in use.
For Windows Server 2012 Release Candidate, there exists no such feature in dedup such as the CSV Cache.
Regarding for the issue that you simply couldn t access some files within the Windows Server 2012 box before installing deduplication feature on that box, this is predicted. Some from the files on the deduplicated volume are reconstructed as deduplication specific reparse point files. They are certainly not accessible unless deduplication feature is installed. For the files which are accessible without deduplication feature installed, it truly is likely them to be not transformed into deduplication specific reparse point files.
Hi Scott, are you aware if there is often a bug in 2012 RTM s Windows Server Backup? I am trying to complete a dedup-aware optimized backup using WSB but regardless of what I do, when I decide on a deduped volume I get the big mistake noted here have replicated this using some environments now: /hyper-v-3-0-server-2012-deduplication-yay-and-vhdx-files
There will still be Issues with Indexing Files!!! Bevor 3, 5 Mio. Files where indexd, now approximately 1Mio. files where found and indexed. Microsoft knows it, yet still no fix for it.
Also SharePoint2013 doesnt index these files, so this really is also no solution.
Problem seems to get in pharsing files via Blockmode, in order that it cant index these files, cause there where deduped. WTF. Dont use ist guys - its late, it since not too long ago - well no solution.
Gonna disable Dedup and buyed a storage with Dedup-Feature.
