  A while back i wrote a post about data deduplication in 2012…. generally a very good feature, but as that specific post talked about, there was a collection of .iso and compressed data where not only did dedup not save me anything, it actually used up more space in the dedup folder than the orginal data size (which i found a little odd) Today i got around to doing something about this and found Disabling data deduplication (via GUI or powershell) only stops further deduplication from occuring – but data that has already been deduplicated will remain deduplicated In order to “move” (re-hydrate ?) the data back to the original files and out of the deduplication store, use the powershell command  start-dedupjob -Volume <VolumeLetter> -Type Unoptimization You can check the status on where this is at by using  get-dedupjob , or, i like using TreeSize which shows the size on disk of specific files…. including the deduplication chunks At this stage – i noticed the o...

  Optimize Storage In Windows To Optimize the Storage in Windows Server 2012, 2012 R2, 2016 and 2019 Windows PowerShell cmdlet is available. It provides the ability to manually perform actions like TRIM, Defragment, etc. TRIM – The parameter is  ReTrim  which generates TRIM and Unmap hints for all currently unused sectors of a volume. Defrag – The parameter defrag/L performs the same TRIM (-ReTrim) as the Optimize-Storage PowerShell cmdlet

First published on CloudBlogs on Nov, 09 2012  Hey folks, We once again have a guest for today's AD RMS Team blog. Today's post is brought to you by Andrey Moskvitin. Andrey is a Technical Solutions Professional who specializes in Security for our Microsoft Russia subsidiary and he's going to help you see how to use File Classification Infrastructure along with our Rights Protected Folder Explorer and an additional third-party tool, the PDF protector offered by our friends at Foxit Software, to protect files of any type using Windows Server 2012. I'm sure you will enjoy learning how to use these tools together to automate protecting of documents based on classification rules. While this is, as Andrey points out, not a totally new feature scenario, it has become an easier and richer one to explore with recent updates and new functionality that have come about around the release of Windows Server 2012. Thanks,  Dan Hi, I am Andrey and today I want to highlight h...

Removing .NET Framework 4.5/4.5.1 removes Windows 2012/2012R2 UI and other features This is Vimal Shekar and Krishnan Ayyer from the Windows Support team. Today in this blog, we will be discussing about an issue that we are seeing increasingly being reported in support. We will look at the effects of removing .Net Framework from a Windows Server 2012/2012 R2 installation. Windows Server 2012 includes .NET Framework 4.5 and Windows Server 2012 R2 includes .NET Framework 4.5.1. The .NET Framework provides a comprehensive and consistent programming model to build and run applications (including Roles and Features) that are built for various platforms. Windows Explorer (Graphical Shell), Server Manager, Windows PowerShell, IIS, ASP .NET, Hyper-V, etc, are all dependent on .NET Framework. Since there are multiple OS components dependent on .Net Framework, this feature is installed by default.  Therefore, you do not have to install it separately. It is not recommended to u...

HYPER V - LỖI KHÔNG ENABLE ĐƯỢC REPLICA SERVER Server Hyper-V vẫn hoạt động bình thường, trước giờ vẫn làm Hyper-V Source replica, giờ chuyển qua làm destination replica thì nhận được báo lỗi hyper v failed to enable the replica server using kerberos authentication Kiểm tra trong event log thì thấy có dòng lỗi khả nghi như sau: Nguyên nhân : có lẽ là do setting làm source replica trước đó, nên trong network interface không có dòng cấu hình ListenIP Khắc phục: chạy CMD với quyền administrator, add thêm dòng cấu hình iplisten vào Bật lại Enable Replica thành công

Khi move các máy ảo từ server này qua server khác, đôi khi sẽ gặp tình huống khác phần cứng (CPU, model v.v..) như lỗi sau: Cách khắc phục: Tắt máy ảo cần move Vào Setting của máy ảo - Processor - Compatibility Chọn " Migrate to a physical computer with a different processor version " 

LỖI "ENABLING REPLICATION FAILED" DO ISCSI DISKS ATTACHED Khi enable replication cho 1 server có gắn card iSCSI sẽ bị lỗi như bên dưới  Nguyên nhân là do tính năng backup (checkpoint) của Hyper-V host lock. Vì vậy cần phải disable tính năng này, làm như sau: Vào Setting - Intergration Services của máy ảo Clear mục " Backup (Volume checkpoint)"
