What happens with data files stored on external (USB) drives ( in shared folders ) if WHS crashes ? RRS feed

  • Question

  • WHS supports external drives. But when attaching these external drives for the first time all data on them are automatically deleted by WHS (!!). So , what happens in the following scenario:

    Let's assume that the local hard drive where WHS has been installed has crashed - for some reason - and I have to re-install WHS (or even to replace the complete pc). Can I then simply re-attach the external drives where all (or most of) the data is stored in shared folders - or will the new installation of WHS simple destroy all these external data when the external (USB) drive is attached (for the first time to this new installation) ?

    Or another question: is it possible to access the data in shared folders which are located on external (USB for example) drives from other computer environments, such as Windows XP - or do the external folders have a special (unreadable) file format or are they protected that other OS environments cannot access it?

    In general: WHS will save (backup) the data of attached local PCs ... but how to securely save (backup) the data stored on WHS itself ??

    Thanks.

    If you leave the USB drive attached and perform a "server reinstallation" then all of your data should be safe. You will need to recreate your users and re-permission any folders, but the data is kept. You should keep the usb drive connected all the time to stop data corruption.

     

    You should be able to plug the drive into another computer and read it - the file structure may look slightly different.

     

    Dont forget thought that WHS doesnt see seperate drives - it pools them all together so if you have multiple drives you may not have everything copied to that one USB drive.

    Klaus,

    External drives don't have the data deleted. You can have them attached, just so long as you don't add them to the data store.

    You have a couple of different scenarios in your question.

     

    1. If you have multiple hard drives in your Server store, failure of the System drive means that all you need to do, is replace the drive with a new one - same size or larger than the failed one and then, when you insert the DVD, select Re-Installation. It can take quite some time as the process will rebuild all the tombstones from your existing data. All you need to do then, is add your clients and Add_Ins etc and your good to go.

     

    2. Replace the complete PC. In this case, the scenario is that you build the new server and then attach the existing drives to the new server, but don't add them to the storage pool. As the drives are NTFS, you can then just copy any information you want to from your 'old' shared folders to your 'new' shared folders.
