Quota usage including any quota thresholds does not change when a file is processed by deduplication. All other FSRM quota functionality, including volume-root soft quotas and quotas on subfolders, will work normally when using deduplication.

Volumes brought under deduplication control may be empty or they may already contain data. If the volume already has data, deduplication may take an extended amount of time to process the data for the first time. This is a normal condition and should be expected. Data Deduplication processes files when the server has available resources and will automatically resume processing.

The rate of processing depends on the system specifications. Administrators can monitor the progress of deduplication by using Windows PowerShell or in Server Manager. After the initial dataset is processed, deduplication has minimal impact on the server, and it does not require manual maintenance.

Data deduplication allows new writing directly to an NTFS volume. Files on the volume are evaluated periodically and processed if they meet the deduplication policy criteria. Deduplication processes files inside an enabled volume once per hour in the background or on additional schedules that you specify by using Throughput mode optimization jobs.

The deduplication feature can process roughly 2 TB of data per volume in a hour period GB per hour when running a throughput optimization job on a single volume. Multiple volumes can run in parallel if CPU core processors and memory are available. The busier the server is, the longer it will take to process the data. If you have a data volume that is very busy, you might consider scheduling a regular throughput optimization job during off-peak hours.

For more information, see Optimization jobs. Running very low on disk space on a deduplicated volume is not advisable because certain types of data access operations can fail unexpectedly. For example, memory-mapped operations on deduplicated files can fail due to lack of disk space.

Notepad is an example of an application that accesses files by using memory-mapped operations. If the volume is at or near zero free space, opening deduplicated files in Notepad may return an error message that says disk access has failed.

Similar data-access failures can occur on sparse or compressed files on a full volume without deduplication installed. We recommend keeping at least one gigabyte of free space on deduplicated volumes to avoid failures.

If the volume is full and you encounter file access failures, consider one of the following options to work around the issue:. Run a Garbage Collection job to reclaim disk space by using an elevated Windows PowerShell command prompt:.

You can use it to determine the expected savings that you would get if deduplication is enabled on a particular volume. The following example shows running DDPEval. When the space savings percent is calculated, you can make an informed decision to install deduplication or not.

By running the Windows PowerShell Measure-DedupFileMetadata cmdlet, you can determine how much potential disk space can be reclaimed on a volume if you delete a group of folders, a single folder, or a single file, and then run a Garbage Collection job.

Specifically, the DedupDistinctSize value will tell you how much space you would get back if you deleted those files. Files often have chunks that are shared across other folders, so the deduplication engine will calculate which chunks are unique and would be deleted after the Garbage Collection job.

In this example, KB of space will be reclaimed if Garbage Collection is run with the —full parameter. When appropriate servers and volumes have been identified, you can enable the feature on the server and assign volumes.

For more information, see Install and Configure Data Deduplication. When it is enabled, the default policies and schedules are created. Process files that have a minimum age of five days according to the Last Modified Time.

If Last Access Time is enabled on the server this is not the default setting , deduplication will use the Last Access Time. Process files in background mode every hour. Do not exclude any directories or file types. The default setting is to process the entire volume. Run a garbage collection job every Saturday at AM. Garbage collection reclaims space on a volume by deleting chunks from the chunk store that are no longer referenced. Download now.
