Help my Windows Server 2012 (2016) deduplicated drive is gone crazy (not releasing space)

I make use of deduplication feature on Windows Server 2012, and Windows Server 2016 quite extensively. And, it does wonders. Its deduplication ranges from 10% (wsus content, backup server) to upwards of 55% ( File Share servers and SCCM Distribution Points with ISOs and .wim images, as well as packages and applications).

Recently, a case was brought to my attention where a  drive with wsusContent on freshly installed Windows 2016 server has started running out of space. Initial drive size was about 100GB, and after fe Continue reading →

WSUS server serving wsusContent; local vs remote.

Ah yes, you have had enough of it. Wsus content folder keeps growing in size day by day. You have tried feeding it 20 GB, then another 50, then 100 GB. No, it won’t stop growing and keeps demanding more and more space.

No worries, there is a solution for that… Maybe… in any case as gecko says ” 15 minutes could save you 15% or more on”  of your valuable disk space on your (v)SAN storage

 

Solution 1)  Have workstation download updates from MS directly

  1.  Downside; traffic, bandwidth, time, multiple unknown variables on how long, amount of bandwidth, cost of bandwidth
  2. To Do:
    1. Set your workstations to report statistics and  detect updates to your internal SUS Server:

      detect updates and report statistics wsus
      detect updates and report statistics wsus
    2. Choose an option to “Do not store update files locally; computers install from Microsoft Update”

 

 

Solution 2) Download to sus server, only what you need

  1. Don’t download the “Express installation files”; downside is it will take longer for workstations to get the necessary updates
  2. To Do:
    1. Check mark “Download update files to this server only when updates are approved”
    2. Uncheck the “Download express installation files”
