In addition to getting the backup privilege an application would need to
specify the FILE_FLAG_BACKUP_SEMANTICS flag to the file open API
(CreatFile()). Otherwise the backup privilege would just have been a
synonym for "all access" on all operations.

Now how to get tar to set this flag on file/dir opens, I don't know.


so long, benny
