Deduplication can get the most work done when resources are available. Servers typically have periods of high activity and times when there is low resource utilization. This consumes server resources and must be considered when planning a deployment. File age policies can be applied to control when files are deduplicated to prevent early or frequent deduplication of files that are still likely to be modified significantly.ĭoes the server have sufficient resources and time to run deduplication?ĭeduplication requires reading, processing, and writing large amounts of data. Good candidates allow time to deduplicate the files. Poor candidates for deduplication are a constantly-mounted SQL Server database that is running virtual machines, and live Exchange Server databases.

The constant access and change to the data are likely to cancel any optimization gains made by deduplication, and deduplication may not be able to process the files.Ī good candidate for deduplication is a file share that hosts user documents, virtual files, or software deployment files that contain data that is modified infrequently and read frequently. Software binaries, cab files, symbols filesĭoes the data access pattern allow for sufficient time for deduplication?įiles that change often and are constantly accessed by users or applications are not good candidates for deduplication. For Details about using the DDPEval tool to evaluate deduplication savings see Step 3: Evaluate savings with the Deduplication Evaluation Tool later in this topic. It is best to run an evaluation on a data sample before you enable deduplication. Results will vary by data type, mix, and size. The following table highlights typical deduplication savings for various content types. Evaluate the following considerations when you select data for deduplication:ĭoes the data have duplication within it?įile shares or servers that host user documents, software deployment binaries, or virtual hard disk files tend to have plenty of duplication, and they will yield high savings from deduplication. Virtualized Backup (Windows Server 2012 R2 only): Backup applications running as Hyper-V guests saving backup data to mounted VHDsĭeduplication can be very effective to optimize storage and reduce the amount of disk space consumed-50% to 90% when applied to the right data. VDI Deployments (Windows Server 2012 R2 only): Virtual Desktop Infrastructure (VDI) deployments using Hyper-V VHD libraries: Virtual hard disk (VHD) file storage for provisioning to hypervisors Software deployment shares: Software binaries, images, and updates General file shares: Group content publication and sharing, user home folders, and Folder Redirection/Offline Files The ideal workloads for deduplication include: Administrators can schedule more aggressive deduplication based on the type of data that is involved and the frequency and volume of changes that occur to the volume or particular file types. The implementation is designed for low memory and CPU usage, and if memory utilization becomes high, deduplication will wait for available resources. The default settings are nonintrusive because they allow data to age for five days before processing a particular file, and has a default minimum file size of 32 KB.

This means that you can install and use the feature without impacting the primary workload on the server. Step 4: Plan the rollout, scalability, and deduplication policiesĭata Deduplication is designed to be installed on primary data volumes without adding additional dedicated hardware.
Step 3: Evaluate savings with the Deduplication Evaluation Tool Step 2: Determine which volumes are candidates for deduplication
To be safe, backup and restore a deduplicated volume to ensure that your deployment is covering the entire dataset.
