how does WHS handle pc backups after system drive failure RRS feed

  • Question

  • Hi

    i have a WHS installed and the sata port 0 went on my MB
    not knowing the port had gone i assumed the drive had gone - so i replaced it
    while trying to re-install WHS i kept getting errors which is when i discovered the sata port was causing the errors

    so i moved the drive to the next available port making sure it was recognized as drive 0 to do a re-install
    after the re-install the WHS did not recognize any of my pc backups

    which meant i had lost all my backups

    i just can't loose my backups just because the system drive fails
    everyone on the forum talks about loosing their media files (from what i understand from reading posts) and the re-install will discover the media files on the other drives in the WHS during installation but i am just concerned about my pc backups coz i can't find anyone who specifically says it will discover the pc backups on the other drives

    what is recommended to ensure the new WHS installation will recognize the pc backups?
    or will the re-installation recognize the PC backups and i just didn't understand the posts properly?

  • This question is a special case of "What happens to my data if a drive fails?" I should write a FAQ. :)

    Here's what happens (and it's true for any drive, not just your system drive):

    Shares: If all your shares were marked for duplication, you will lose no data from your shares. If a share didn't have duplication set, you will lose data if any files in that share were stored on the failed drive. Windows Home Server will normally help you through this somewhat, but you don't get a comprehensive list, I'm afraid.

    Backups: The backup database is not duplicated. If any component of the database was on the failed drive, you will lose some or all of your backups. What's lost will vary; use the database repair wizard and it will do what it can. This is by design; the database is huge and is usually the largest single consumer of disk space on your server. In addition, you still have your home PCs, so you can just back them up again. (While I agree with this philosophy, you may not.)

    Add-ins: Windows Home Server offers the ability for an add-in to store it's data in the storage pool, and in addition the add-in can set a flag that will enable duplicaiton on that stored data. So whether you will lose configuration/data from your add-ins depends on the add-in developer; if they didn't store configuration data in an appropriate location, or if they stored it without duplication, you may lose data here.

    System drive specific: You will have to reinstall add-ins. You will have to recreate users. You will have to re-join computers to your server, which may require you to uninstall the connector from one, then use the original connector CD (this is likely to be required if you have an OEM server, not if yours is home-built).

    Non-WHS data (such as applications you install using remote desktop): will be lost if it was stored by you or the applicaiton you installed on the failed drive. This includes OS customizations that Windows Home Server doesn't expose in the console, added software such as media or database servers, etc.

    I'm not on the WHS team, I just post a lot. :)
