SYMPTOMS

If you use the Backup program (Ntbackup.exe) in Windows 2000 or Windows XP to restore or to catalog a tape backup that was created by using Microsoft Windows Server 2003, you may receive the following error message:
Backup Device Error

CAUSE

The Backup program in Windows Server 2003 can allocate and read tape block sizes up to 64 kilobytes (KB). However, the Backup program in Windows 2000 and Windows XP can allocate and read tape block sizes only up to 32 KB. Therefore, the Backup program in Windows 2000 and Windows XP cannot restore a tape that uses block sizes that are larger than 32 KB. The Backup program in Windows Server 2003 can restore tapes with block sizes up to 64 KB.

RESOLUTION

Windows XP
