  • cvd.exe consumes CPU
    Posted: 07-13-2010, 8:00 AM


    Windows 2003, SP2

    Siampana 8, Sp4 /deduplication on disk.

    My problem:

    On the client the cvd.exe process consumes a lot of CPU.

    If 3 or 4 subclients backup procedures are running the cvd.exe consumes till 100% of the CPU and the backup jobs run very slow.

    Any idea or solution?

    Thanks to all

    What agents are installed on this machine?  Depending on what is on the machine and what is running at any given point, will allow folks to properly target their replies.

    Im going to assume this is just a windows file system agent without DCE.  The first thing i would check is, if software compression is turned on for this subclient.  If it is, turn it off and see if things improve.  If it doesnt or if its not on, then check if signature generation for dedup is turned on the client.  If its is, either move signature generation to the media agent or turn it off temporarily to see if the situation improves.  Both of these options are on the properties of the subclient under the storage device tab.  Since you mentioned you have mulitple subclients, ensure you perform these steps on each one.

    Thanks for the infos......but:

    - Compression is turned off (HW+SW)

    - Signature on the client or on the MA do not change anything.

    - I'll try with the signature turned off on one subclient

    Backup test with one subclient ( compression and deduplication disabled)

    CVD.exe uses about 40% of the CPU .
