On our data server we backup disk to disk with robocopy.
In the error log there are some files with files-names with special characters which cannot be copied.
As i found out this happens if names break the 255 limit in dos-names (if you save with the notepad as ascii) or when there is no translation of special-characters from other international ansi-codes-names.
When i tried to delete or rename them windows cant find this files - they block the whole directory structure.

The only way to get rid of them would be a reformat of the file system - which is not simple for the main productive system.

Is there a way for windows 2000 to rename these hidden charcaters? (i tried zap but that didnt work - i tried renaming from command-prompt with batch file - also unsuccesfull)
And last not least is there a way for windows 2000 to disable these wrong ascii-signs?
regards
Sebastian

Which version of Robocopy are you using?

And would the Windows 2000 NTbackup not allow you a method getting around the issue, since Robocopy will not be able to get the system state of the Windows 2000 server.

robocopy version 1.96, but robocopy is just the way where the error appears.
the backup to tape is working- but the corruption of the file-system is done from windows2000 clients not from robocopy .
So its an issue of ntfs allowing to write dos-names which cant be accesed by windows2000.
