Backup server spec

Posted on 2005-04-26

Hi All,

To use a utility such as symantec live state recovery or to restore a backup server to your main servers state using a backup tape, does the backup server has to have the same spec as the original. i.e. does it have to be exactly the same make, model, ram, harddrive size etc..

Help much appreciated.

    No it does not. The trick is how you bring the server back into Active Directory. You have to be careful not to do an authoratative restore otherwise you can mess up your time and have to call MS to fix (Expensive too) If you are standalone than you should be ok. Install OS configure services and restore systemstate. You will need to reinstall apps too. Only if you are trying to restore filesystem will you have issues.

    If you use the imaging part of Live State, your model of backup server should have the EXACT same disk controller.
    There also will be issues if you have a dual processor and restore to a single processor.
    The hard disk should be at least as large as the original.
    Failure to do so will give you the BSOD because of differences in the HAL.

    Restoring from an image is a faster and cleaner way than going from a tape backup.

    If you schedule incrementals during the day, then a restore from the image should be relatively painless.

    Accepted Solution

    You can restore system state to a machine with differing hardware.

    Just install a base OS onto the new server, to the same SP level. Then restore system state from backup media.

    When you get the BSOD - and you probably will as stated above because of HAL issues - boot from Win2k CD. Then choose INSTALL. When the install finds a copy of Windows then chose REPAIR. This is basically an in place repair of Windows and the HAL will be as per the new machine.
