  • Win XP VolSnap Shadow Copy Error

    I have a Windows XP Pro SP2 computer that every so often gets the following event log when backing up using Retrospect. The issue will persist until the computer is rebooted and then will come back a few weeks later.

    Event Type: Error
    Event Source: VolSnap
    Event Category: None
    Event ID: 20
    Date: 27/05/2008
    Time: 11:00:25 PM
    User: N/A
    Computer: SERVER
    Description:
    The shadow copy of volume D: was aborted because of a failed free space computation.

    I have seen this error on Windows Server 2003 and I know there is a Microsoft KB out there for that error but it doesn't apply here.

    The error is coming up I believe because the backup software is trying to initialise the Open File part of windows (VSS) and it normally works but for some reason this comes up after a period of time. The backup software has error messages in its log with the following:

    Can't use Open File Backup option for Shared on DATA (D, error -1017 (insufficient permissions)

    Has anyone else encountered this issue?

    Thanks

    Re: Win XP VolSnap Shadow Copy Error

    I have exactly the same problem.

    I am using Windows XP SP3.

    I have just upgraded my system disk from 200GB to 1TB and cloned all the software to proportionately larger partitions.

    Retrospect 7.5 was working fine until then. Now this appears.

    A restart fixes the problem.

    It looks like it must have something to do with the large number of clusters.

    My error log event is identical:

    I'm looking for a solution.
