Sorry, I forgot you needed renaming. So -I option to xargs may be
useful for you.

OK, try something like this:

  sh -c 'cp "$0" /tmp/data.backup/${HOSTNAME}".${0:2}"' {} \;

find /tmp/var -mmin -60 -a -iname '*.sql' -type f \
 | xargs -n 50 basename -a \
 | xargs -I NAME echo cp /tmp/data.backup/NAME \
 /tmp/var/$HOSTNAME.`date +%Y%m%d-%H.%M.%S.%N`.NAME.backup

You should be bonza, fab, good to go :)

Let us know if that does the trick,
