RE: Short 8.3 file names on restore from NTBackup

Hello,
Thank you for using newsgroup!
Based on my research, Ntbackup in Windows 2000 does not back up short file
names when you back up files. Only way to do this is to copy the files from
one place to another. There is not programmatically way to traverse through
all files, and add the short file attribute. This has been fixed in Windows
XP and Windows 2003 Server in which we added the function
SetFileShortName(). This allows applications (in this case NTBACKUP) to
explicitly set the short name on a file. In other words, we do backup up
the 8.3 short file names.
Besides the workarounds in KB814848, you could modify the registry entries
that use the 8.3 short file names to point to the new short file names. The
following registry keys may use the 8.3 short file names:
A default instance of SQL Server
- HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSSQLSERVER (value
ImagePath)
-
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSSQLSERVER\Performance
(value Library)
- HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\SQLSERVERAGENT
(value ImagePath)
A named instance of SQL Server
- HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSSQL$instance_name
(value ImagePath)
-
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSSQL$instance_name\Per
formance (value Library)
- HKEY_LOCAL_MACHINE\SYSTE

| I had to use NT Backup on an XP machine to back up and restore a large
amount
| of data on a Windows 2000 SP4 server. The user data on the server was
full
| of files with really long names with unusual characters. Upon restore I
got
| the following message in the restore log for many of the files:
| Warning: Unable to set the short 8.3 name for "<FILENAME>".
| Reason: The parameter is incorrect.
| I understand that this shouldn't be a problem as long as there are no 16
bit
| programs trying to access the files. Is that correct and should I be
| concerned?
|
| Thanks.
