Do you use logrotate?
Do you use logrotate's compression?
Maybe use some kind of snapshots, like:
#!/bin/bash
find /var -type f -printf "%k %p\n" > /tmp/usedspace.new
if [ -f /tmp/usedspace.old ]; then
cat /tmp/usedspace.old | while read LINE
do
set $LINE
OLDSIZE=$1
OLDFILE=$2
NEWSIZE=`grep "$OLDFILE\$" /tmp/usedspace.new | cut -d " " -f1`
if [ -n "$NEWSIZE" -a "$OLDSIZE" != "$NEWSIZE" ]; then
echo "$OLDFILE: $OLDSIZE => $NEWSIZE"
fi
done
fi
mv -f /tmp/usedspace.new /tmp/usedspace.old
