Windows Server 2016 – Whats New in Data Deduplication

Deduplication intends to eliminate repeating data to create a single instance. The creation of the single instance improves storage utility and works well in a network with heavy network transfers.

Some may confuse deduplication from data compression, which identifies repeat data within single files and encodes the redundancy. In simple terms, deduplication is a continuous process that eliminates excess copies of data, therefore, decreasing storage demands.

Data deduplication applies to Windows Server the Semi-annual Channel and Windows Server 2016. Data deduplication in Windows Server 2016 is highly optimized, manageable, and flexible.

The new elements of data deduplication in Windows Server 2016 are:

The Updated Features

Support for Large Volumes

It was present in earlier versions where volumes were partitioned to fit data sizes above 10TB. Windows Server 2016, data deduplication supports volume sizes up to 64TB.

What is the Added Value?

The volumes in Windows Server 2012 R2 had to be appropriately portioned in the correct sizes to ensure optimization was keeping up with the rate of data transfer. The implication here was that data deduplication could only work on volumes with data of 10TB or less. The performance also depends on existing workloads on write patterns.

What is Different?

Windows Server 2012 R2 uses a single thread and input and an output queue for every volume. This is to maximize optimization and make sure jobs do not fall behind affecting the volume’s overall saving rate, and large data sets have to be broken into small volumes. The volume size depends on the expected partition size, the maximum size is between 6 and 7TB for high volumes and 9 and 10TB for low volumes.

Windows Server 2016 has a new way of working the data deduplication runs on more than one thread and uses multiple input and output for every volume. This routine introduces a new routine that was only possible after dividing data into small chunks.

Support for Large Files

In earlier versions, any files approaching the 1TB size were not eligible for deduplication. Windows Server 2016 supports files with a maximum of 1TB.

What is the Added Value?

For Windows Server 2012 R2 you cannot use large files for deduplication due to reduced performance in the deduplication process queue. Windows Server 2016 deduplication for files up to 1TB is possible enabling you to save a large volume of work, for example, reduplicating large backup files.

What is Different?

Windows Server 2016 deduplication process uses a new streaming and mapping structures to improve and increase the deduplication output and access. Besides, the process can now optimize when there is a failure instead of restarting the entire process. Deduplication affects file with a capacity of 1TB.

The New Features

Support for Nano Server

Nano server support is a new feature and is available in any Nano Server Deployment option that features Windows Server 2016.

What is the Added Value?

Nano servers is a headless deployment in Windows Server 2016 that need a smaller system for tracing resources, enables quick startup and needs fewer updates and restarts than the Windows Server Core Deployment version.

Simple Backup Support

A Windows Server 2012 R2 supported Virtualized Backups like Microsoft Data Protection Manager after successful manual configurations. Windows Server 2016 has some new default backups that allow for seamless data deduplication for Virtual backups.

What is the Added Value?

For this to happen in earlier versions of Windows Server, you must manually tune deduplication settings as opposed to Windows Server 2016 that has a simplified process for its Virtualized backup applications. Server 2016 enables deduplication for a volume the same way the General Purpose File Servers.

Support Clusters Operating System Rolling Upgrade

Data is capable of supporting new Cluster OS Rolling Upgrade feature in Windows Server 2016.

What is the Added Value?

The failover clusters in Windows Server 2012 R2 could have a mix of nodes that run deduplication alongside nodes that operate Windows Server 2016 versions of deduplication.

The improvement adds full access to data that are Deduplicated during the rolling upgrade; this allows the gradual rollout of the new version of Data deduplication on an existing Windows Server 2012 R2 cluster without allowing for downtime during the upgrading process.

What is Different?

Earlier versions of Windows Server, a failover cluster required that all nodes in a cluster be of the same Windows Server version. In Windows Server 2016 version, the rolling upgrades allow clusters to run in mixed modes.
