You can upgrade to Server then, that would be more reliable. Joe wrote: Would upgrading to be worth it if we are only doing the deduplication as a clean up prior to migrating the files to the cloud? When possible, Data Deduplication can automatically use volume features such as mirror or parity on a Storage Spaces volume to reconstruct the corrupted data.
Additionally, Data Deduplication keeps backup copies of popular chunks when they are referenced more than times in an area called the hotspot. The Unoptimization job, which is a special job that should only be run manually, undoes the optimization done by deduplication and disables Data Deduplication for that volume.
A chunk is a section of a file that has been selected by the Data Deduplication chunking algorithm as likely to occur in other, similar files. The chunk store is an organized series of container files in the System Volume Information folder that Data Deduplication uses to uniquely store chunks.
Every file contains metadata that describes interesting properties about the file that are not related to the main content of the file. The file stream is the main content of the file.
This is the part of the file that Data Deduplication optimizes. The file system is the software and on-disk data structure that the operating system uses to store files on storage media. A file system filter is a plugin that modifies the default behavior of the file system. To preserve access semantics, Data Deduplication uses a file system filter Dedup. A file is considered optimized or deduplicated by Data Deduplication if it has been chunked, and its unique chunks have been stored in the chunk store.
The optimization policy specifies the files that should be considered for Data Deduplication. For example, files may be considered out-of-policy if they are brand new, open, in a certain path on the volume, or a certain file type.
When a file's file stream has been optimized, Data Deduplication replaces the file stream with a reparse point, which enables Data Deduplication to preserve the access semantics for that file. A volume is a Windows construct for a logical storage drive that may span multiple physical storage devices across a one or more servers. Deduplication is enabled on a volume-by-volume basis.
A workload is an application that runs on Windows Server. An extra copy of critical data is created, and any file segment with more than references is collected as most popular chunks. Once the deduplication process is active, scanning and fixing of errors becomes a continuous process. Inspection of the deduplication process and host volumes takes place on a regular basis to scrub any logged errors and fix them from alternative copies. An optional deep scrubber will walk through the whole data set by identifying errors and fixing them, if possible.
When the disk configurations are set to mirror each other, deduplication will look for a better copy on the other side and use it as a replacement. Some of the features described above does not work in all Window Server editions and may be subject to limitations. It is installed through the DDPEval. However, planning for deduplication before implementation is necessary because of the various situations in which its use may not be applicable.

When to Apply Windows Server Deduplication Since Windows Server file deduplication works on the file level, its operations work on a higher level than a block level, as it tries to match chunks of data. Deduplication is all about fulfilling this growing demand. Why is Deduplication Feature Found on Servers? Data deduplication in a straightforward feature and will take a few minutes to make it active.
However, it is safe to do so to make sure the entire process is configured correctly. Preparing for Windows Server Duplication Click on start Click on the run command window Enter the following command and press enter this command runs against selected volume to analyze potential space for storage : DDEval. Benefits of Windows Server Deduplication Windows Server deduplication brings several benefits to an organization, including the following: Reduced storage allocation Deduplication can reduce storage space for files and backups.
Efficient volume replication Deduplication ensures that only unique data is written to the disk, which reduces network traffic.
Increasing network bandwidth If deduplication is configured to run at the source, then there is no need to transfer files over the network. Cost-effective solution Since power consumption is reduced, there is less space required for extra storage of both local and remote locations. Features of Deduplication 1. Transparency and Ease of Use Installation is straightforward on the target volume s.
This feature uses the following approach when processing special files: Post procession : when new files are created, the files go directly to the NTFS volume where they are evaluated on a regular schedule.
The background processing confirms file eligibility for deduplication, every hour, by default. The scheduling for confirmation time is flexible File age: a setting on the deduplication feature called MinimumFileAgeDays controls how long a file should stay on the queue before it is processed. The default number of days is 5. The administrator can configure it to 0 to process all files. Type of file and location exclusions : you can instruct the deduplication feature not to process specific file types.
You can choose to ignore CAB files, which do not help the process in any way as well as any other file type that requires a lot of compression space such as PNG files. New posts Latest activity.
