Restore points deleted (yet again - sorry)

    Hello - All my restore points are getting deleted on every re-boot,
    accompanied by volsnap event ID 25 "The shadow copies... were deleted because
    the shadow copy storage could not grow in time." I have seen a few mentions
    of this problem elsewhere, but no fix. I have tried turning system restore on
    and off, with no effect. Restore points are created with no problems, but
    invariably deleted at the next boot.

    System is a rather odd dual-boot of Vista HP with XP: an Acer Aspire, which
    runs XP on a hidden partition exclusively to run Acer's own Arcade media
    application in an "instant-on" mode: on exiting this application, XP
    hibernates, then resumes when a special hotkey is pressed (as far as I can
    see it never reboots XP). But the Vista restore point deletions happen
    whether or not XP is actually run. So I can't apply any of the usual fixes.

    Can anyone suggest a fix and/or explain why this might, after all, be a
    symptom of the dual-boot problem even though XP is not actually running?

    Thanks and regards - Mike.

    I think what you are doing is the equivalent of booting to XP then back to
    Vista. The Vista restore points would be deleted "by design". Not that you
    have to like it. I don't.

    Hi Mike,
    I have no solution to your dual boot problem, other than to consider
    an alternative such as MS Virtual PC or other VM product. I run Vista
    as the host with an XP virtual machine using Virtual PC and am quite
    happy with the solution. Depending on your reasons for dual boot, you
    might be happy with the VM solution.

    It sounds like the obvious answer to your shadow copy storage problem
    is space, but you seem like someone that knows what they are doing and
    I figure you have already considered whether or not you have enough
    free space for the shadow copy feature of drive protection.

    XP is the one deleting your Restore Points. It does it with dual boot upon
    next restart.

    Hello - Thanks to all who replied to this. It turns out that the problem has
    to do with the hibernation file.

    I believe the shadow copy system may be getting "confused" by the
    hibernation (not booting) of XP in the Acer "instant on" partition though I
    am not sure how, so that on every Vista re-boot a changed hiberfil.sys is
    detected and the system attempts to shadow it in its entirety. This
    effectively overloads the shadowing system leading to the event id 25 (which
    is not a symptom of the well-known dual-boot issue).

    In any case, turning off hibernation in Vista then back on again allows the
    shadow copies to survive re-boot and the system returns to correct operation

    Regards - Mike
