Greetings
I've been backing up an Oracle database with tar and dd trough a shell
script in order to save time. First I bak up the datafiles with tar in
the filesystem with
tar cbf 126 PROD.tar /u04/oradata/PROD
and then I store it in tape using
dd if=PROD.tar of=/dev/rmt/0cn bs=63k
and it works really fast.

The problem is that when I need to restore the back up it just take tooo
long. As an example, it took almost 4 hours to unpack an archive from
tape to the filesystem ( I used tar xbf 126 /dev/rmt/0cn).
Is there a better way to do this? is the block size Im using to large?
