Home Server Backup Fails: Cannot backup volume {797...} because it does not exist RRS feed

  • Question

  • I am trying to back up my Dell XP Pro (SP3) computer using the Windows Home Server (SP1) connector software. At 47%, the "Backup Status" reads "The backup failed because the volume is currently missing. The event log on the server contains the volume name."

    Checking the event log on the client gives the following Application Errors:

        Date:    11/25/2008
        Time:    9:16:50 PM
        Type:    Error
        User:    N/A
        Computer:  [...]
        Source:       HomeServer
        Category:   HomeBackup
        Event ID:    776
        Description:
            Cannot back up volume {797e8aca-9bec-11dd-9294-001d6a17e589} because it does not exist.

    And ~10 minutes later:

        Date:    11/25/2008
        Time:    9:26:57 PM
        Type:    Error

    The DiskExt.exe utility from SysInternals.com does not show a {797e8aca-...} GUID volume:

    The interesting thing is that the WHS's event log seems to indicate a successful backup of C:\ and no backup errors. Only the connector client backup event log and UI show the error. This does not leave me with a lot of confidence in the backup.


    Any thoughts or ideas on how I can solve this backup problem?

    Thanks,
    Jim

  • Problem fixed. Thank you!

    I had pulled the 1 TB drive off this client computer to put on the server. The backup needed to be reconfigured in order to no longer be attempting to backup the 1 TB drive.
