By flagging CrashPlan traffic appropriately, we should be able to handle it in a different way at the router, that is, give it less priority, or give other traffic higher priority. Some applications may set or offer configurations for other values. Windows 7 by default appears to send out all packets with DSCP value of zero. For the record, I’m no networking expert, so this is based on what I learnt over a few days messing around with things and a lot of Googling. In order to utilise this I looked into the network TOS & DSCP settings within Crashplan which allows us to select four preset options or specify a custom DSCP value. I thought of the QoS features of my SOHO router – a Draytek 2920, to improve the traffic flow. Currently the home cable serivce is rated as 10mbps down, 0.25mbps up (I know is pretty low, I need to upgrade). I soon found that the upload burden was taking its toll on the network – any other device in my home would be slow and laggy to browse web pages while Crashplan was doing its uploading thing. I started using Crashplan as an online backup solution. This post doesn’t discuss router configuration (to be part of a separate post), just Crashplan and DSCP on Windows 7.

#Crashplan upgrade failed code
It talks about Differentiated Services Code Point or DSCP, QoS, Netmon packet monitor, Group Policy settings, and various unsuccessful fixes to the problem of Crashplans DSCP setting having no apparent effect either due to a bug or limitations of Windows 7. This post describes the issues I had trying to stop Crashplan’s upload traffic slowing down everything else on the network while utilising the available bandwidth for very large uploads. I spent a fair amount of time trying to get to the bottom of this and so thought I would share my experiences, and partial successes. Windows 7 Home Editions do not appear to have group policy editor (gpedit.msc) installed as standard.

Update : The solution described at the end of this post is applicable to Windows 7 Professional and other non-‘home’ editions. Edit: See this post for a working practical config with a router that uses these settings.
