    I recently built a small WHS server build, and I was just wondering, is it normal to have a backup time of more than 6 hours when I'm copying my hard drive for the first time? I am trying to back up 250gb from my home computer.

    The very first backup of any client in your LAN will take the longest amount of time (since there are no previous files stored in the backup database).  I could see 6 hours for your first backup.  I would be more concerned if it was 6 hours for each subsequent backup.

    All my WHS back ups seem to take a really long time since upgrading to Win7.  I'm on a 100Mbs network but while backing up it only ever gets to about 1.5 % network utilisation - I'm sure this used to be closer to 20-50% on XP.  Am I doing something wrong or do I have to put up with the backups taking several hours?

    Any help gratefully received as I've tried manually setting the 2 NICs to 100 duplex (no other settings options available on the WHS card settings page) - this seemed to make things worse if anything!  I've disabled MacAffee and that didn't help.  I have come to the end of my tech capability...

    Network behaves fine otherwise - iTunes and other streaming apps run data from WHS OK with network utilisation up in the 20s, normal network access to WHS for remote user folders etc also good - it just seems to be back up that's slow.

    (total backup is about 100Gb)

    Hi,
    high volume (100 GByte) backup volume and 100 MBit network do not match too well. To support Full Duplex, not only the NICs, but also the switch (hubs do not support Full Duplex at all) and the network cables must have adequate quality. And Gigabit equipment for the home network is not that expensive any more (although you will need an extra switch for the LAN, if you only used the router before, since most routers are still 100 MBit switches).

    Once a backup run through successfully, the volume is reduced, but it depends from what changes daily on the client. If you have a big amount of data changing daily or run a tool to defragment the client disk each day, backup will need much more time to save changed data or compare the content of the clusters to be backed up.

    Best greetings from Germany
    Olaf

    The answer?  Turn Jumbo Packets down to lowest setting on client - seems old Realtek card in WHS couldn't handle them.
