How can I exclude D: from image backup? RRS feed

  • Question

  • I was recently trying to do a Windows Backup but it failed with

    Volumes larger than 2088958 megabytes cannot be protected.

    The problem turns out my D: is larger than that. However, when you try to configure Windows Backup to do an image backup, it automatically includes D: whether you want it to or not, and there is no option in the UI to exclude D: I cannot state strongly enough how serious a UI design and/or implementation bug this is. Where is the best place to report this bug?

    Now if I change the letter from D: to Z:, there is no problem, the UI now gives me the choices of whether to include Z: or not. The problem is in order to do my software testing I need to use D: but I do not want it included in the backup. Is there some other way than the GUI to configure Windows Backup properly? Why is D: so special anyway?

    It’s probably a long shot, but does the BIOS boot sequence point to a secondary drive as the first boot device, rather than your Windows drive?

  • Hi Eric,

    I would contact your internal system administrator or licensing contact. You may get covered support incidents with Microsoft.

    Would you provide some more information about the system?

    Is a UEFI BIOS (firmware) based system?

    Are both drives dynamic?

    What is the configuration?

    EFI\UEFI backups and restores are not as simple as working with basic disks. Same for the dynamic disk in a non-UEFI system.

  • The system is a Dell 3500 workstation which boots from a RAID 0 Array using a Dell Factory Image.

    Currently the active partition is the Recovery partition, which presumably runs the O/S from the C: partition.

    The BIOS boot sequence boots from the RAID 0.

  • I am using Windows 7 Professional SP1 x64

    No, the system is not UEFI - it is a Dell Precision 3500 workstation, and Dell only uses UEFI on their server products.

    I did not think there were any dynamic drives because I thought you could only convert drives to dynamic with the server version of Windows. Is diskpart telling me they are dynamic, or does the Dyn column mean something different.

    I know that disks 1 through 8 are all GPT because I initialized them that way.

    Is there any other configuration information you need?

  • Well, that's an interesting way to do things.

    Disk 0, 1 & 2 may appear as dynamic if they are part of the RAID.

    Microsoft Connect is one location to send feedback. You can access it with your Windows Live sign-in you created for this forum.

    http://connect.microsoft.com/, although it doesn't appear that Windows 7 is open at this time.

    I cannot tell you why the backup utility wants D:\ to be another drive. After A< B< C there really is no convention that I could find for drive lettering.

    D should not be special.

    I still believe that you should initiate a Microsoft support incident for the backup. That would enable the support person to involve the appropriate resources to answer your question.

  • Actually there are no dynamic disks - the output from 'list disk' is terrible - the first three lines are skewed.

    It is impossible to create dynamic disks in Windows 7 - only the server versions of Windows support dynamic disks. The Disk Manager UI is very misleading and will walk you through creating an array, until the end when it errors out because you cannot create a dynamic disk. If you run diskpart from the command line and try to convert a disk to dynamic you get an error saying the O/S does not support it.

    Off hand I would say this looks like a defect in Windows backup. I was hoping someone would have a workaround for me - such as - is there some secret configuration file for Windows Backup somewhere?

    Cheers, Eric

  • Hi,

    You may try to use wbadmin to backup the system and exclude partition D..



    Also, can you manually create an System Image to exculde partition D?
