Does demigrator stop when there is network/disk traffic? RRS feed

  • Question

  • I'm interested in using WHS but I have one big concern...

    Let's say I just transferred 50 GB of data to my WHS.  The share I copied this data to has duplicated enabled.

    Five minutes pass and demigrator starts duplicating my data.

    I now start copying this same data from my WHS to a different machine.

    Will WHS stop the demigrator process or will my throughput be really horrible for a while?  This is important to me because I'm using my WHS to stream 1080p videos and I don't want demigrator copying data from the hard drives I'm currently streaming off of.

  • No. DEMigrator runs once per hour, or when you change duplication on a share. It won't stop due to network or disk activity; if it dis so in theory it might never finish duplicating files. 

    Basically, Microsoft has prioritized protecting your data above other activities.

    I'm not on the WHS team, I just post a lot. :)

  • Makes sense.

    Thanks.

  • I wish that was the case with my box, demigrator hogs the CPU and causes any video currently being streamed to stutter or stop until the CPU load drops again.  Are there any workarounds for this?  HP MediaSmart EX485 is fully up to date with patches.

  • No workarounds at all. Usually this is related to both demigrator.exe and qsm.exe. The stuttering is not seen in higher spec units, if the right motherboard and nic are used. Sorry.
