Manual backups work fine on a W7 client whereas Automatic backups fail with errors 773, 770 RRS feed

  • Question

  • Hello guys,

    I've been running WHS on a custom-built machine for few months now. Recently, I installed PP3 Beta on my WHS as it better supports Windows 7; I run W7 on 2 machines, another two machines run Vista SP2 and XP Professional.

    WHS usually backs up all my machines automatically without any issues except for one of my W7 machines (which is my PVR) - it always fails with event IDs 773 and 770 when the backup is run automatically although manual backups complete successfully. Auto backup is set to wake the computer up.
    This particular W7 installation is fresh (4 days old) and auto backup worked fine only once. Before that, on the same hardware I had Vista SP2 installed which was running auto backup just fine.
    When I click the details... button on the failed backup task I see that the duration is 0 seconds. Does this make any sense?

    I used the connector troubleshooter from the WHS toolkit. Apart from a problem with uPnP I didn't see anything of interest. I have a box running pfSense (FreeBSD based router) on my home network and I know that uPnP is not completely supported in it so I don't care about this problem that much.

    I am going to run Chkdsk /R right now and see if this might help. If anyone have any idea please let me know.
    I also configured the NIC on this particular machine for 100/Full instead of Automatic negotiation, prehaps this will make a difference...



    Thanks in advance,

    Itay

  • Are there any other errors in event log (system and application)?

    Can you please post some details for event IDs 770 and 773?

  • I appreciate your effort to help.

    I pasted the details of events 773 and 770 from the Application event log below; the source for both events is HomeServer and the task category is HomeBackup. There are no other relevant errors or warnings in the Application or System event logs.

  • That's strange, network connection has been lost. And a manual backup is always running?
    Please report this to MS connect.
