If you are backing up a file system for which you have a driver, use that instead. You will save room on the backup media. If you are backing up an Oracle raw partition, you may be better off dumping the data and backing that up. There may also be transaction integrity issues with backing up Oracle raw partitions this way. I highly recommend W. Curtis Preston's excellent book Unix Backup & Recovery.
