What is the best method for workstation backup on DPM 2012? RRS feed

  • Question

  • As currently we use DPM 2012 to backup users data and users reported slowing the performance of the laptop without enabling on-the-wire compression.

    What is the best configuration for users using DPM 2012 for everyday recovery point with 7 days retention range and without compromising on user's laptop performance?

    Please add / modify this registry value on the clients machines to help with reducing DPM Disk IO.

  • Hi,

    On-wire compression puts more workload on the clients machine as it takes CPU to compress the data before sending over the network.  That will help if the client is disconnected from fast network and is on a network with slow bandwidth so not as much data needs to be transmitted.  You may need to increase the WaitInMsPerRequestForClientRead further to minimize the effect of using on-wire compression.

  • Protecting client computers with DPM

    " On wire compression: decreases the size of data being transferred during replica
    creation and synchronization and allows more data throughput with less impact to
    network performance. However, this option adds to the CPU load on both the DPM
    server and the protected computers. The amount of compression and improvement on
    network performance depends on workload "

    Performance and DPM


    Have a nice day !!!

  • Hi Eugene,

    The on wire compression is disabled, even is disabled user reported slowing down the performance of the laptop. If I enable this will more worse does it?

  • You can try enable this feature and see network performance. CPU must load more.

    Slowing the performance may occur:

    1) Bad (old) clients disks

    2) Old clients network adapters 

     

    Have a nice day !!!

  • I do not want to compromising user laptop's performance compared to congestion network performance.

  • I created 2 Protection Groups for these laptop backup:

    1. PG without on-the-wire compression. (Some users have big data applied with regedit "Optimizing Client Computer Performance).

    2. PG with on-the-wire compression. (Some users have big data applied with regedit "Optimizing Client Computer Performance).

    Windows Registry Editor Version 5.00

    [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft Data Protection Manager\Agent\ClientProtection]
    "WaitInMsPerRequestForClientRead"=dword:00000050

    Today, one of the user reported and complaining that the computer running to slow. The user is under PG number two, PG with on-the-wire compression and enabled the optimizing client computer performance.

    I concluded PG with on-the-wire compression enabled is useless at this point.
