- Data Deduplication in Windows Server 2016
Apr 01 2016 by Will Gries at blogs.technet.microsoft.com
Since we introduced Data Deduplication (“Dedup” for short) in Windows Server 2012, the dedupe team has been hard at work improving this feature and our updates in Windows Server 2016 are no exception. When we started planning for Windows Server 2016, we heard very clearly from customers that performance and scale limitations prevented use in certain scenarios where the great space savings from dedupe would really be useful, so in Windows Server 2016, we focused our efforts on making sure that dedupe is highly performant and can run at scale. Here’s what’s new in 2016:
Support for Volume Sizes Up to 64 TB
In Windows Server 2012 R2, dedupe optimizes data using a single-threaded job and I/O queue for each volume. While this works well for a lot of scenarios, you have to consider the workload type and the volume size to ensure that the dedupe Processing Pipeline can keep up with the rate of data changes, or “churn”. Typically this means that dedupe doesn’t work well for volumes greater than 10 TB in size (or less for workloads with a high rate of data changes). In Windows Server 2016, we went back to the drawing board and fully redesigned the dedupe Processing Pipeline. We now run multiple threads in parallel using multiple I/O queues on a single volume, resulting in performance that was only possible before by dividing up data into multiple, smaller volumes:

Finally, start thinking about the possibilities for when Windows Server 2016 is released in 3Q2016. I know I'm certainly looking forward to testing the multi-threaded deduplication that is said to be much improved over 2012 R2, as seen in the schematic above. Think about it, 2 vCPUs for that W2016 VM, using two of my Xeon D home lab's 8 cores for a very good cause, quietly deduping the extended family's daily VEB backups.
Oh, and don't forget those VMs, Hyper-V or VMware. This same Windows Server 2016 VM can also hold your Veeam Backup & Replication v9 Repository. Yes, VEB can backup to not just network shares, but to Veeam Repositories as well.
Now you see why I'm thinking I'll be willing to give 2016 two vCPUs, given how important its role may become if this dedupe role works out well for my home lab's backup needs. Of course, with important NTFS filesystems that I don't wish to possibly corrupt (no ReFS support for dedupe yet), automated shutdown of my vSphere 6 home lab is required, for peace of mind during those summer thunderstorms and winter snowstorms.
Is Microsoft Windows Home Server's famed Single-instance storage effectively back again, without the huge "rehydration" penalty?
Most seductive for me is the potential for a combination of using this newly enhanced deduplication in conjunction with backup products like Veeam Endpoint Backup FREE 1.5 (VEB), where we should be able to see much of the old Windows Home Server benefit of compressed and deduplicated storage, but hopefully without the huge slowdown that was seen during "rehydration" of backups during bare-metal restores. It was frustrating, because the CPU and disk utilization would be low for the whole restore. This also meant that even restoring from SSDs was slow, since the disk wasn't the bottleneck.
That proprietary PC backups database also tended to bog down on restores even more, once that database exceeded about 2TB in size. A typical single PC bare metal restore took more than 10x as long as a straight restores from products like native Windows backup, VEB, or Acronis would.
Let's hope those days are behind us. Window Server 2016's expected 3Q2016 GA date is not far away, this should be interesting!
I used Windows Server 2016 Technical Preview 5 (beta) for this article, download details below.
This entire article is really for informational purposes, I'm not recommending you actually use such beta code for any production purposes.
By the way, VEB 1.5 compression and dedupe within drive volumes its backing is pretty outstanding, with quick backing up of duplicate ISOs featured in the first of the 3 technical videos below.
Careful testing will be needed! See also these words of warning:

You will also want to avoid deduplicating appliances for primary storage. Why? Well, these devices will constantly be de-duping your backups, which doesn’t work so well if Veeam needs them for things like reverse-incrementals or synthetic fulls. Deduplication is fantastic for secondary storage though as the data tends to be ‘colder’.
