How is WHS 2011 handling backups for a mirrored drive (RAID-1)? RRS feed

  • Question

  • I have Windows Home Server 2011 automatically backing up my PC.
    The relevant specifications are that my 500GB system drive is mirrored and my PC is running Windows 7 Ultimate SP1.
    I expected WHS to backup 500GB of data, but it is backing up 1TB of data. This is an image of what's going on.
    I am hoping to get the answers to the following questions:
    • Why is it doing this?
    • If I had to restore from a backup, would I need to first setup another RAID-1 mirror?
    • If I were to break the mirror, how would the backup feature react?
    Thank you for reading, and I look forward to your answers.

  • Are you using an on-board RAID controller?

  • No, I am using the software RAID built-in to Windows.

  • Somehow I am under the impression that only hardware raid can be used since this transparant to the WHS OS.

    But I cannot find anything from Microsoft on it. :|
