Answer:
The Ntbackup.exe tool in previous versions of Windows has been replaced with the new Windows Server Backup tool in Windows Server 2008. If you've been using Ntbackup.exe and now plan to use the new Windows Server Backup that comes with Server 2008, there are several things that you need to keep in mind.

First, let me address your question. Windows Server 2008 does not support recovering from backups that were created with the old Ntbackup.exe. However, Microsoft is offering a new version of Ntbackup.exe for people who want to recover data from the old backups that were created using Ntbackup.exe. Keep in mind that this "special" version of Ntbackup.exe is only for recovering backups that you created with previous versions of Windows; you can't use them to create new backups in Windows Server 2008.

You can check out this link for more information on this special version of Ntbackup.exe called "Windows NT Backup - Restore Utility."

Here are some additional tips that you may find helpful when working with the Server 2008 Windows Server Backup utility.

1. The backups require NTFS-formatted volumes.
   
   
2. You can back up to hard disks (both internal and external) but the disks must be locally attached.
   
   
3. You can back up to DVDs and remote-shared folders in Windows Server 2008.
   
   
4. If you plan to use scheduled backups, then you'll need a separate, dedicated disk.
   
   
5. If you back up to an external disk, the disk will be dedicated to backups and you won't be able to see it in Windows Explorer. The idea is that you can remove the external disk for off-site storage.
   
   
6. Backing up to tape isn't supported in Windows Server 2008 but there is support for tape storage drivers.
   
   
7. You can't back up volumes larger than 2,043GB with the Windows Server Backup tool.
