Hi all,

Is it possible to apply a backup image to differnt hardware, i.e. different raid controllers etc using the bare metal restore method....i.e. recovery partition, restore boot and system partions and then copy the registry to alternate "new" primary partition as i know this works on identical hardware. How would i load scsi contollers\drivers etc before os has been loaded for the first time. (in essence creating a dual boot system and them blowing away initial repair partition)

Thanks

It IS possible. And it'll be very easy if the hardware is recognised by NT4 already.

What I mean by that is that if NT4 can find the drivers by itself when it detects the hardware change, then you'll have no problem whatsoever.

Failing that, NT4 should detect new hardware and ask to load the drivers as it finds them with the new hardware wizard - which I'm sure you're familiar with.

I've done this myself.. A company shipped us a ghost image of an NT4 system/boot partition which we ghosted onto a laptop as a demo.

NT4 automatically decided there was new hardware left, right and centre and loaded the appropriate drivers for each.

We didn't have SCSI drivers when we did it, but I expect it should be exactly the same situation.
The other difference is the method of restore - backup for you... but again, the same logic should apply.

Cheers,
Tim.

NT 4.0 doesn't have plug-and-play, so I don't think that it'll automatically detect the new hardware after restoring. I think what you'll need to do is install your new machine from scratch. The device dection code that NT uses during an install should find the new RAID controller. Then restore the registry and data from the backup. Be sure both servers are NOT online at the same time, otherwise you might get name or TCP/IP conflicts.

I agree with the second answer. NT does not have the detection feature (plug-n-play). For NT you will either need to have the same hardware. You might be able to get away with a different nic card and video card if you set the drivers with the video to standard VGA for the image. The hard drive might be a different story. It might work sometimes and others it may night. I would suggest if you have different hardware for NT you will be better off in the long run to just build it from scratch.

It will not work with Windows NT 4.0, if windows doesn't have the drivers for it loaded, even if its on the windows CD (in most cases not even with Windows 2000, even though Win2K is Plug and Play, Plug and Play loads after the Hard Drives which means that the OS needs first to boot from the HardDrive).
To make sure that windows will boot to the new SCSI you will have to first install the driver for the new SCSI then backup and then you can restore to a computer that has a different SCSI. You can install as many drivers for SCSI devices even if they are not installed on your computer. You must however make sure that there is no conflict, and that the driver you are installing is not going to damage the SCSI device thats already in. The best way to do it whould be install the new driver DONT REBOOT SO IT DOESNT LOAD. Backup, UNINSTALL the new driver. Now your old system should work and when you restroe to the new system it will also work.
Another way that might work is restoring to the new system then if/when you get the blue screen error INACCESSABLE BOOT DEVICE. run the intallation from the WINDOWS NT CD and choose repair.
If you are using a Disaster Recovery option that comes with some Backup programs (like Veritas BackupExe) they have ways you can redirect a whole system to a new computer with different hardware.
Hope this helps.

To add an additional SCSI to a system go into Control Panel and choose SCSI Devices > Drivers and click on add.

The reason it worked for TimTheToolMan is because he was using an IDE HardDrive which Windows NT does't have a problem with.
It might work in any case since a lot of SCSI devices may work with other drivers.
