Backups failing on one PC only...others successful RRS feed

  • Question

  • The failing PC has several larger drives, portions of each of which are set to backup. The backups worked flawlessly for a long period and continue to work well on lesser machines. The Event Viewer says;

    Backup set 1 on SLAYSERV failed: Microsoft.HomeServer.Backup.Protocol.ProtocolException: Client / Server connection lost

    at Microsoft.HomeServer.Backup.BackupOp.BackupSetOperation.RunWithoutCatch()

    at Microsoft.HomeServer.Backup.BackupOp.BackupSetOperation.Run()

    The Home server reports:

    Failure Details for Volume (Local Disk):

    An error occurred reading or writing from server storage. D:\folders\{00008086-058D-4C89-AB57-A7F909A47AB4}\Data.4096.72.dat 

    WriteFile 1117


    Does anyone have an idea of what might be wrong?

  • Usually indicates a problem with your one of your server hard drives.  Even though your other clients backup fine that particular cluster is probably unique to the machine having problems backing up. 

    I suggest running a full chkdsk on your servers disks in accordance with this FAQ:

  • The best application I've used to check and report on hard drive health is Hard Disk Sentinel, see http://www.hdsentinel.com/. this does not resolve the issue for you but you will know well ahead of failure and take corrective action.

    For me, I've given up on WHS until the next release. I ran into to many issues and just could not afford the time to resolve them. Also I just did not understand a number of the issues and don't have the time to become an expert. I went to Win7 and now have four Raid1 arrays. For now this solves my storage issue. I think the next step is to install another Win7 system and put 12 Raid1 arrays in it. When I reach the limits of this system I'll have a total of 30TB (today I use about 8TB) and I don't think I need 30TB but who knows. I never thought that I'd use 8TB.

  • Hi Jgt,

    You didn't reply to your own thread... perhaps someone could have helped you out:


    By the way SMART data is only advisory - SMART data may indicate a healthy drive when it fact it has faults.
