How do I enable deduplication?
After you directly disable data deduplication, the volume remains in a deduplicated state and the existing deduplicated data is accessible. So to undo data deduplication on a volume, use the Start-DedupJob cmdlet and specify Unoptimization for the Type parameter first. Then you could disable it.
How does Windows Server 2012 deduplication work?
Disk / Data Deduplication is a feature new to Windows in Server 2012 and has recently been improved in Server 2012 R2. Data Deduplication is based on the idea that if you have multiple copies of the same file you can only actually write one to disk and then just provide pointers to the copy.

Monitoring the event log can also be helpful to understand deduplication events and status. To view deduplication events, in File Explorer, navigate to Applications and Services Logs, click Microsoft, click Windows, and then click Deduplication.
How do you implement data deduplication?
Implementing data deduplication
- Determine database capacity requirements.
- Determine database log size requirements.
- Determine which client nodes have data that you want to deduplicate.
- Determine whether you want to implement server-side data deduplication, client-side data deduplication, or a combination of both.
How do I run deduplication manually?
You can run every scheduled Data Deduplication job manually by using the following PowerShell cmdlets:
- Start-DedupJob : Starts a new Data Deduplication job.
- Stop-DedupJob : Stops a Data Deduplication job already in progress (or removes it from the queue)
How do I undo deduplication?
To undo data deduplication on a volume, use the Start-DedupJob cmdlet and specify Unoptimization for the Type parameter. After you disable data deduplication on a volume, you can perform all read-only deduplication cmdlet operations on the volume.
How does Microsoft deduplication work?
Data Deduplication, often called Dedup for short, is a feature that can help reduce the impact of redundant data on storage costs. When enabled, Data Deduplication optimizes free space on a volume by examining the data on the volume by looking for duplicated portions on the volume.
What are the types of deduplication?
There are two main methods used to deduplicate redundant data: inline and post-processing deduplication. Your backup environment will dictate which method you use. Inline deduplication analyzes data as it is ingested in a backup system. Redundancies are removed as the data is written to backup storage.
How do I check my deduplication status?

What is Dedup optimization?
Optimization. The Optimization job deduplicates by chunking data on a volume per the volume policy settings, (optionally) compressing those chunks, and storing chunks uniquely in the chunk store.

After you disable data deduplication, the volume remains in a deduplicated state and the existing deduplicated data is accessible. The server stops running data deduplication jobs for the volume and new data is not deduplicated.
What is deduplication technology?
Data deduplication is a process that eliminates excessive copies of data and significantly decreases storage capacity requirements. Deduplication can be run as an inline process as the data is being written into the storage system and/or as a background process to eliminate duplicates after the data is written to disk.

What is the maximum deduplicated volume size in Windows Server 2012 R2?
In Windows Server 2012 and Windows Server 2012 R2, volumes had to be carefully sized to ensure that Data Deduplication could keep up with the churn on the volume. This typically meant that the average maximum size of a deduplicated volume for a high-churn workload was 1-2 TB, and the absolute maximum recommended size was 10 TB.
