Deduplication is probably one of the coolest features in Windows Server 2012 and I haven't written about it yet. Until now!
Fans of enterprise storage have grown to love deduplication for the massive space savings is can bring on things like volumes that host VMs or backup archives. The problem has been that there is a high barrier to entry for a lot of SMBs that can't necessarily afford the proper hardware and/or licensing to use deduplication properly. In some cases, these organizations will roll out a ZFS solution. ZFS on Linux is a relatively new development, so up until very recently, it would require a Solaris derivative or a BSD that was not encumbered by the GPL license. Because of this, many smaller organizations have skipped deduplication in favor of just buying more disks.
Well, now the wait is over. In Server 2012, deduplication is baked into the OS for no additional cost and is incredibly easy to configure and get rolling with. Check out the YouTube video after the break for a quick walkthrough on setting up some basic deduplication settings on your Windows Server 2012 file server.
