This is the case with ALL raw partition backups. A raw partition backup
basically dumps the disk to tape. There is no concept of files or space used
(unless you are using flashbackup(?)) so the dump does not know what is data
and what isn?t. That is why raw partition backups are so much faster than
file system backups. The down side is, as you have discovered, that it backs
up the entire disk and you have to restore the entire disk.
