SYMPTOMS
After installing Service Pack 5 on Windows NT 3.51, you may start to see
verify errors in NTBackup. The errors you see, in either your NTbackup
screen or Backup.log, will have the following format:
*File information found on tape:
*%FileName% %Size% %Date% %Time%
*File information found on disk:
*%FileName% %Size% %Date% %Time%
*Difference encountered in alternate file data.
*The file %FileName% is different.
The problem seems to occur more frequently on Macintosh or large NTFS
volumes.
CAUSE
This is caused by NTBackup checking the stream size of the data which may
change every time you run backup.
RESOLUTION
This problem seems to be more of a nuisance than actual file problems, but
can cause NTBackup to degrade in performance, especially on large volumes.
So far, we have not seen any cases which actually showed file corruption.
You can simply choose not to verify after backup or apply the Hotfix
available as mentioned below.
STATUS
Microsoft has confirmed this to be a problem in Windows NT version 4.0.
This problem has been corrected in the latest U.S. Service Pack for Windows
NT version 4.0. For information on obtaining the Service Pack, query on the
