    Shadow Copy lag issues


    I am having some issues with shadow copy taking up a lot of disk time and causing lag. Lag spikes are occurring approx every 30 seconds to a minute.

    In the resource monitor, under System, I currently have approximately 100+ (approx 3.5 pages) \device\hardiskvolumeshadocopy instances running. (Hard to count exactly as they keep changing.)


    Total CPU usage is ~15%; Memory usage is 40%; Disk usage fluctuates between 10% and 60% (up to Total: 16 GB/sec) at idle. (I know a comp is never truly at idle, but the only active windows up right now are this Chrome window, Task manager, Resource Monitor and the PowerShell.)


    Each shadowcopy instance/file is grouped in sets of seven:

    harddiskvolumeshadowcopyxxxxx

    harddiskvolumeshadowcopyxxxxx\

    harddiskvolumeshadowcopyxxxxx\$Mft

    harddiskvolumeshadowcopyxxxxx\$Secure:SDS

    harddiskvolumeshadowcopyxxxxx\$Extend\$Reparse:$R:$Index_Allocation

    harddiskvolumeshadowcopyxxxxx\$Secure:$SII:$Index_Allocation

    harddiskvolumeshadowcopyxxxxx\System Volume Information


    My Shadow Copy Storage association is

    For volume: (CShadow Copy lag issues :)\\?\Volume{95564550-02d1-4593-afdb-8ac81a1584c2}\
    Shadow Copy Storage volume: (CShadow Copy lag issues :)\\?\Volume{95564550-02d1-4593-afdb-8ac81a1584c2}\
    Used Shadow Copy Storage space: 1.68 GB (0%)
    Allocated Shadow Copy Storage space: 2.77 GB (1%)
    Maximum Shadow Copy Storage space: 22.3 GB (10%)


    I am running Windows 10 Pro, 64 bit. The hard drive is a SSD.

    Any other data you need?


    A couple of days ago, I resized to the current 10% max space and created a restore point. Originally I thought the lag was a conflict between VSS and Carbonite (it appeared that the two were in a continuous Do loop with each other). I limited the Carbonite back-up to only running in the middle of the night and to not do a continuous back-up.
    It fixed the issue for about a day.

    Going back in today, the huge number of shadowcopy instances is back. In addition, the manual restore point I created a couple of days ago is gone. There are no other restore points.
    Regarding the potential conflict with Carbonite: the Carbontie files that were present originally in Resource Monitor are not there today.


    I would like to keep shadowcopy running but it makes some applications extremely difficult to use due to the lag.

    How do I stop the constant read/write to disk? Better yet: how do I stop the frequent lag spikes?

    :)

    Shadow Copy lag issues

    VSS (Shadow Copy)

    We are using Windows 10 1703 with shadow copy enabled. For some reason on my own PC I am able to right click on a folder and see "Previous Versions" however for everyone else the list is empty. I can see the Volume Shadow Copy service does start up and run
    however still do not see any folders in previous versions. Has anyone come across this before? We are not blocking or hiding the list.

    On one of the computers the event log shows:

    General

    Volume Shadow Copy Service error: Unexpected error calling routine QueryFullProcessImageNameW. hr = 0x80070006, The handle is invalid.

    On other computers there are no errors but the previous versions list is still empty on those.
